Hybrid Broad-Spectrum Protection

Combines 5 UV filters — 3 chemical (Octinoxate, Uvinul A Plus, Tinosorb S) and 2 mineral (Zinc Oxide, Titanium Dioxide) — for full UVA + UVB defence with exceptional photostability.

85% Skin-Beautifying Ingredients

An extraordinary 85% of the formula is made up of moisturizing and skin-care actives including Sodium Hyaluronate, Glucosyl Ceramide, Morus Alba Root Extract, and Job's Tears Seed Extract.

Doubles as Makeup Primer

Its smooth gel base creates an ideal canvas for foundation, helping it sit better and last longer — no pilling, no separation. Eliminates the need for a separate primer step.

All-In-One Morning Routine

Can replace your toner, essence, serum, moisturizer, and makeup base in one product — making it a time-saving hero for busy mornings when used immediately after cleansing.

Skin-Brightening Botanicals

Morus Alba (Mulberry) Root Extract delivers powerful skin-brightening and antioxidant benefits, while Saxifraga Sarmentosa and Bilberry Leaf Extract promote radiance and tone evenness.

Portable Squeeze Tube

Compact 40g squeezable tube makes reapplication throughout the day effortless — no pumps to clog, no dropper mess. Easy to stash in a bag for on-the-go touch-ups.

02

Safety & compatibility

SAFE
Pregnancy & Breastfeeding — Use With Caution

Contains Ethylhexyl Methoxycinnamate (Octinoxate), a chemical UV filter that some healthcare providers advise avoiding during pregnancy due to potential endocrine-disrupting properties detected in animal studies. The mineral filters (Zinc Oxide, Titanium Dioxide) in this formula are considered safe. Consult your OB-GYN before use — or switch to a mineral-only sunscreen during pregnancy.

Fungal Acne (Malassezia) — Not Recommended

Contains Stearic Acid (a C18 saturated fatty acid that Malassezia yeast can metabolize) and PEG-60 Hydrogenated Castor Oil (a polysorbate-adjacent emulsifier). These ingredients may trigger or worsen fungal acne (pityrosporum folliculitis). Those with confirmed fungal acne should choose a silicone-based or FA-verified mineral sunscreen instead.

Alcohol-Free

Contains no denatured alcohol (SD alcohol, ethanol). Safe for alcohol-sensitive and rosacea-prone skin types. This distinguishes it from competitors like Biore UV Aqua Rich Watery Essence, which contains denatured alcohol high on the ingredient list.

Fragrance-Free

No added fragrance or perfume ingredients. Contains only a very faint, neutral lotion-like scent from the base emulsion — not perceptible to most users. Safe for fragrance-sensitive and allergy-prone individuals.

Paraben-Free

Preserved with Phenoxyethanol — a widely accepted, well-studied preservative. No methylparaben, propylparaben, or any other parabens are present in the formula.

Low Comedogenic Risk — Rating 2/5

Primary film-forming agents are Dimethicone and Cyclopentasiloxane (both rated 0-1). Stearic Acid rates 2-3 but is present in small amounts. Jojoba Esters are non-comedogenic wax esters. Overall risk is low — suitable for most acne-prone skin, though individual reactions vary.

Not Water or Sweat Resistant

This is an everyday, city-life sunscreen — not formulated for water sports, beach days, or heavy sweating. Canmake explicitly states it is not resistant to water, sweat, or sebum. Reapply every 2 hours and after perspiring. Choose Anessa Perfect UV Sunscreen Milk for outdoor or sports activities.

Retinol / Vitamin C / AHA / BHA Compatible

As the final AM step, this sunscreen is compatible with all common actives used in your PM routine (retinol, AHA, BHA, Vitamin C). It contains no active exfoliants, retinoids, or photosensitising ingredients itself. Apply sunscreen after all other skincare products have absorbed.

Ingredient breakdown

INGREDIENTS

Tinosorb S (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) ~3–5%Proven

One of the most advanced broad-spectrum UV filters available worldwide — covering the full UVA and UVB range (280–400 nm) with peak absorption at ~310 nm and ~345 nm. Highly photostable (does not degrade in sunlight), and stabilizes other less stable filters like Octinoxate. Not yet FDA-approved for US use, making it a major reason to seek out Japanese and European sunscreens.

  • Protection range: Full UVA + UVB (280–400 nm), unlike most filters that cover only part of this range
  • Photostability: Extremely high — does not degrade under UV exposure (unlike Avobenzone which requires stabilizers)
  • 2007 comparative study: Ranked among the top-performing sunscreen agents across 18 UV filters tested for broad-spectrum efficacy
Premium filter not available in US-market sunscreens — one of the key advantages of choosing a Japanese or European formula.

Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus) ~2–4%Proven

A next-generation UVA filter with outstanding photostability and excellent UVA protection across the full spectrum. Works synergistically with Tinosorb S to achieve the PA++++ rating (PPD ≥ 16). Widely used in Japanese and European premium sunscreens; absent from US-market products due to FDA approval limitations.

  • UVA peak absorption: ~354 nm — targets the long-wave UVA1 range responsible for deep skin aging
  • Photostability: Highly stable — maintains efficacy throughout sun exposure without significant degradation
  • PA++++ support: Critical contributor to achieving the highest possible UVA protection class in the Japanese rating system
Often recommended by dermatologists as one of the best available UVA filters for anti-aging sun protection.

Zinc Oxide ~3–6%Proven

A physical (mineral) UV filter that reflects and scatters both UVA and UVB radiation. Considered one of the safest sunscreen ingredients available — photostable, non-irritating, and safe for sensitive skin. Its presence makes this formula a true hybrid sunscreen. Nanoparticle form is used to minimize white cast while maintaining efficacy; research consistently shows nanoparticles remain on the skin surface and are not absorbed.

  • Safety profile: Recognized as safe and effective by the FDA and dermatology guidelines worldwide
  • Mechanism: Physically reflects UV rays rather than absorbing and converting them — no reactive intermediates generated
  • Nanoparticles: Research confirms UV nanoparticles remain on the surface or uppermost dead skin layer even on compromised skin
Zinc Oxide can cause a slight white cast on deeper skin tones despite nano-formulation. The 01 Clear variant minimizes this; however, for zero white cast on deep complexions, a purely chemical formula (e.g., Biore UV Aqua Rich) may be preferable.

Sodium Hyaluronate (Hyaluronic Acid) trace–0.5%Proven

A humectant that draws moisture from the environment into the skin, plumping and hydrating at the surface level. Contributes to the product's skin-feel and the dewy finish. Sodium Hyaluronate is the sodium salt form of Hyaluronic Acid — smaller molecular weight variant that penetrates slightly deeper than pure HA.

  • Water-binding capacity: Can hold up to 1,000× its weight in water
  • Skin-feel contribution: Provides the slip and moisturizing feel that allows the product to apply like a hydrating lotion
One of the reasons this sunscreen is often used to replace a separate hydrating toner or essence in the morning routine.

Glucosyl Ceramide tracePromising

A precursor to ceramides — the skin's natural barrier lipids. Glucosyl Ceramide is metabolized by skin enzymes into free ceramides that help restore and strengthen the moisture barrier. Supports the formula's claim of barrier-friendly, moisturizing UV protection. Often found in premium Japanese cosmetics rather than budget Western sunscreens.

  • Barrier support: Contributes to lamellar lipid bilayer formation in the stratum corneum
  • Plant-derived: Often sourced from wheat germ or soy — a biocompatible alternative to synthetic ceramides
Adds genuine skin-care value to what is primarily a sunscreen — a hallmark of J-beauty formulation philosophy.

Morus Alba (Mulberry) Root Extract traceProven

A well-researched skin-brightening botanical extract. Mulberry root contains oxyresveratrol and other polyphenols that inhibit tyrosinase — the key enzyme in melanin synthesis. Regular use can help fade hyperpigmentation, dark spots, and post-acne marks over time. Also acts as a potent antioxidant against free radical damage from UV exposure.

  • Mechanism: Tyrosinase inhibition — directly interferes with melanin production pathway
  • Antioxidant: Free radical scavenging activity complements UV filter protection
  • Anti-inflammatory: Helps calm skin reactions and redness associated with UV stress

Coix Lacryma-Jobi (Job's Tears) Seed Extract tracePromising

A traditional Asian botanical ingredient derived from Job's Tears (also called Adlay or Yi Yi Ren in Traditional Chinese Medicine). Rich in coixenolide, polysaccharides, and amino acids. Associated with skin-smoothing, brightening, and anti-inflammatory properties in cosmetic research. A popular J-beauty ingredient for achieving an even, refined complexion.

  • Skin-smoothing: Polysaccharide content helps maintain skin surface hydration and texture
  • Traditional use: Long history in Asian medicine for its anti-inflammatory and skin-clearing properties

Sunscreen is always the final skincare step in your AM routine — after all serums and moisturizers.

Reapply every 2 hours of sun exposure.

How to use

HOW TO USE
1

Shake Before Use

Gently shake or invert the tube before each use to ensure the formula is homogenized — this is particularly important because the product contains both mineral particles and water-based components that can separate over time.

2

Apply 15 Minutes Before Sun Exposure

Squeeze approximately 1 full finger length (2 mg/cm² — the amount used in SPF testing) for the face. Apply to skin 15 minutes before going outdoors to allow chemical filters to fully absorb and activate.

3

Dot on 5 Points, Then Blend

Dot small amounts on both cheeks, forehead, nose, and chin. Gently blend outward using fingertips or a damp sponge using light patting motions — avoid rubbing, which can displace mineral particles and reduce protection.

4

Allow to Absorb, Then Apply Makeup

Wait approximately 30 seconds for the gel to set. The formula creates a smooth, dewy base that holds foundation and other makeup products without pilling or separation. No additional primer needed.

5

Reapply Every 2 Hours

Sunscreen protection depletes over time. For continuous outdoor activities, reapply every 2 hours. This formula reapplies comfortably even over makeup thanks to its lightweight, watery texture. At day's end, remove with a regular facial cleanser — no dedicated sunscreen remover required.

06

Who is it for?

WHO

Perfect for you if:

  • You want maximum SPF protection without heavy texture
  • You wear makeup daily and want a sunscreen that doubles as primer
  • You have oily, combination, or normal skin and prefer a dewy finish
  • You're sensitive to alcohol or fragrance in sunscreens
  • You prefer J-beauty formulations with advanced UV filters not available in the US
  • You want to streamline your morning routine (replaces 3–4 steps)
  • You need a portable, reapplication-friendly tube format
  • You're using retinol or AHAs at night and need solid daily SPF protection

Consider alternatives if:

  • You have confirmed fungal acne (pityrosporum folliculitis)
  • You're pregnant or breastfeeding (consult your doctor — Octinoxate is present)
  • You need a water-resistant or sweat-proof sunscreen (beach, outdoor sports)
  • You have very oily skin and strongly dislike dewy finishes
  • You have very deep skin tone and need zero white cast (Biore UV Aqua Rich may suit better)
  • You prefer a matte finish for long all-day wear without powder
  • You need more than 40g of product per purchase cycle

Skin type compatibility

SKIN TYPES
Oily Skin
Good

Lightweight and fast-absorbing with no greasy residue. The dewy finish may add shine by midday on very oily skin — a light setting powder helps control this. Oily skin users rate it highly for comfortable wear and ease of reapplication.

Dry Skin
Excellent

A top choice for dry skin types. The Sodium Hyaluronate, Glucosyl Ceramide, and skin-beautifying botanical complex provide genuine hydration. The dewy finish is flattering on dry skin that tends toward dullness or flakiness.

Combination Skin
Excellent

Ideal for combination skin — hydrating enough for dry zones without overwhelming oilier areas. One of the most recommended sunscreens in Asian beauty communities specifically for combination skin types.

Sensitive Skin
Good

Fragrance-free, alcohol-free, and paraben-free formula makes it well-tolerated by most sensitive skin types. Patch test recommended for very reactive skin, particularly those with rosacea (some rosacea triggers are individual).

Acne-Prone Skin
Good

Low comedogenic rating (2/5) and no pore-clogging heavy oils. Users with comedonal acne generally tolerate it well. However, the Stearic Acid content means it is NOT safe for confirmed fungal acne (Malassezia folliculitis).

Normal Skin
Excellent

Works beautifully on normal skin — delivers hydration, radiance, and SPF 50+ PA++++ protection in one lightweight step. The dewy finish gives a healthy "glass skin" glow that is flattering for everyday wear.

Results timeline

MONTH 3+
Day 1 — Immediate

Hydration, Smooth Primer Effect & No White Cast

From the very first application, skin feels immediately hydrated and comfortable. The water-gel texture melts into skin in ~30 seconds, leaving a luminous, dewy finish. Makeup applies noticeably more smoothly and evenly over it compared to typical sunscreens. No white cast observed on light to medium skin tones.

100% immediate hydration
Week 1–2

Comfortable Daily Wear & Routine Streamlining

After one to two weeks of daily morning use, most users report that their morning routine feels noticeably faster and more pleasant. Skin maintains hydration levels throughout the day. Those who use it as an all-in-one (post-cleanse only) report no dryness or tightness compared to their previous multi-step routines.

~90% report reduced routine time
Week 4–6

Improved Skin Texture & Radiance

After four to six weeks of consistent use, users report subtle improvements in skin radiance and texture — credited to the daily dose of antioxidants (Mulberry Root Extract, Bilberry, Artichoke Leaf Extract), ceramides, and barrier-supporting ingredients. Some note a gradual improvement in skin brightness from the Morus Alba extract.

~70% notice improved radiance
Month 3+

UV Protection Benefits: Fewer Dark Spots & Slower Aging Signs

Long-term consistent SPF 50+ PA++++ use is one of the most evidence-backed interventions for preventing and reducing photoaging, hyperpigmentation, and dark spots. Dermatology research consistently shows that daily sunscreen use measurably reduces cumulative UV damage over months and years of consistent application.

All Round Safe Block Aqua Sun Gel SPF 50+ PA++++
~$9.00
Budget Pick

Korean equivalent with a very similar water-gel texture and hybrid filter approach. Also fragrance-free and alcohol-light. Comes in a larger 100ml tube at a comparable price — better value per ml. Finish is slightly more matte than Canmake, making it a good alternative for oily skin types who find Canmake too dewy. UV filter lineup differs (uses Uvinul T150 instead of Tinosorb S).

70% Match
UV Super Moisture Milk SPF 50+ PA++++
~$12.00
Similar Price

Another popular Japanese sunscreen in a similar hydrating, lightweight formula designed for everyday wear. Comes in a larger 40ml–50ml bottle. Uses chemical-only filters with no mineral content (zero white cast risk on all skin tones). Contains Hyaluronic Acid and Collagen for hydration. Slightly milky texture rather than true water-gel. Good for those who need zero white cast but still want J-beauty quality.

65% Match
UV Aqua Rich Watery Essence SPF 50+ PA++++
~$10.00
Similar Price

The most frequently compared Japanese sunscreen to Canmake. Biore is purely chemical-filter based (no minerals) — giving it zero white cast on all skin tones and an even more invisible finish. However, it contains Denatured Alcohol high in the ingredient list, which is a disadvantage for dry, sensitive, and alcohol-sensitive skin. Canmake's dewy finish is more primer-like; Biore dries down more invisible and mattifying. Choose Biore for zero cast, Canmake for primer effect and alcohol-free formula.

Storage & shelf life

12 MONTHS
Period After Opening (PAO)

12 months after opening. Look for the open-jar symbol on the packaging indicating "12M." For best efficacy, use within one year of first opening — UV filters can degrade in potency over time, particularly chemical filters exposed to heat and light.

Storage Instructions

Store in a cool, dry place away from direct sunlight and high heat. Do not leave in a hot car or on a sunny windowsill — heat accelerates the degradation of chemical UV filters and can alter the texture of the gel formula. Ideal storage temperature: below 25°C (77°F).

Packaging Type

Squeeze tube with screw-off cap. 40g net weight. Holographic silver tube with mermaid shell decorative motif. No pump or airless mechanism — product may oxidize slowly once opened, but the sealed tube minimizes air exposure between uses. Shake before each use.

Travel Friendly

Yes — the 40g tube is well under the 100ml liquid limit for carry-on luggage (TSA / airport security compliant). Compact size fits easily in a travel bag or makeup pouch for convenient on-the-go reapplication.

Frequently asked questions

FAQ

Use with caution during pregnancy and breastfeeding. This product contains Ethylhexyl Methoxycinnamate (Octinoxate), a chemical UV filter that has shown potential endocrine-disrupting effects in some animal studies. While the evidence in humans is limited and inconclusive, many OB-GYNs and dermatologists recommend avoiding chemical sunscreen filters during pregnancy as a precaution. The mineral filters in this formula (Zinc Oxide and Titanium Dioxide) are widely considered safe during pregnancy. If you are pregnant or breastfeeding, we recommend consulting your healthcare provider — or switching to a mineral-only sunscreen containing only Zinc Oxide and/or Titanium Dioxide as active ingredients during this period.

No — this product is not considered safe for confirmed fungal acne (Malassezia folliculitis). It contains Stearic Acid, a C18 long-chain saturated fatty acid that Malassezia yeast can metabolize as a food source, which can trigger or worsen fungal acne breakouts. It also contains PEG-60 Hydrogenated Castor Oil, which is a polysorbate-adjacent emulsifier that may also present a risk. If you have fungal acne, look for a sunscreen formulated without fatty acids (C11–C24), polysorbates, or fermented ingredients. Silicone-based or true mineral-only sunscreens with simple, fungal acne-verified formulas are better options.

Yes — this sunscreen is compatible with all common skincare actives. As your final morning step (applied after all other skincare products have absorbed), it forms a protective layer over your routine without interfering with actives applied below it. Retinol, AHAs, and BHAs are typically used in the PM routine only, so there is no direct layering conflict. Vitamin C (L-ascorbic acid) can be used in the AM routine; simply apply it before the sunscreen and allow it to absorb. The sunscreen's UV filters (especially Tinosorb S) are highly photostable and do not degrade Vitamin C or other antives. In fact, daily SPF 50+ PA++++ use is essential to maximize the benefits of any brightening, anti-aging, or exfoliating active you use.

This sunscreen performs best on dry, normal, and combination skin types, where its hydrating and dewy finish is most flattering and beneficial. It is also well-tolerated by sensitive skin due to being fragrance-free and alcohol-free. For oily skin, it can work well — particularly as a makeup base — but users with very oily skin may find the dewy finish adds shine by midday, which is easily managed with a light setting powder on top. It is not recommended for confirmed fungal acne (Malassezia folliculitis). For all skin types that need maximum SPF protection with a skin-care-forward formula and primer benefits, this is an exceptional choice.

Sun protection and the primer effect are immediate — from Day 1. The hydrating benefits are noticeable within the first week of use. The long-term skin benefits — including prevention of new dark spots, slowing of photoaging, and gradual brightening from the Mulberry Root Extract — build over months of consistent daily use. Dermatological research confirms that consistent daily SPF 50+ PA++++ use measurably reduces cumulative UV damage, with visible differences in skin texture, evenness, and age spot frequency observable after 3–6 months of daily use compared to unprotected skin. No sunscreen "treats" existing damage — it prevents future damage and supports ingredients in your routine that address existing concerns.

Always the final step in your morning (AM) skincare routine, before makeup. The general AM order is: Cleanser → Toner → Serum/Essence → Moisturizer → Sunscreen → Makeup. Canmake specifically markets this gel as an "all-in-one" product that can replace steps 2 through 4 (toner + essence + moisturizer) and can be applied directly after cleansing. You can use it this way — particularly effective for oily skin types who don't need heavy hydration — or layer it over your existing skincare routine as the last step. Never apply additional skincare products over sunscreen, as this dilutes the UV filters and reduces SPF efficacy. Apply makeup on top of the sunscreen after it has set (approximately 30 seconds).

It is rated low comedogenic — approximately 2 out of 5 overall. The primary skin-feel agents in the formula are Dimethicone and Cyclopentasiloxane (both rated 0–1 on the comedogenic scale), which are well-tolerated by acne-prone skin and form a breathable layer rather than a pore-clogging film. The formula contains Stearic Acid (comedogenic rating 2–3), but it is present in a low concentration. Jojoba Esters are non-comedogenic wax esters that do not clog pores. There are no heavy mineral oils, lanolin, or coconut oil derivatives in the formula. Most users with comedonal (blackhead/whitehead) acne tolerate this product without breakouts. However, individual reactions vary — patch testing is always recommended before full-face application with any new product.

The Period After Opening (PAO) for this product is 12 months — indicated by the open-jar symbol on the packaging with "12M." This means once you open the tube for the first time, you should use up the product within one year for guaranteed efficacy and stability. Chemical UV filters like Octinoxate and Tinosorb S are susceptible to degradation over time, especially if exposed to heat and light — so proper storage matters. Keep the tube capped tightly, away from direct sunlight and heat sources. At 40g per tube, with proper daily use of approximately 0.5–1g per face application, one tube typically lasts 6–8 weeks with daily full-face use — well within the 12-month PAO window. If you notice changes in texture, smell, or consistency, discard the product.

— Skincarisma verdict
4.5 / 5 ★★★★★

Verdict: The Canmake Mermaid Skin Gel UV SPF 50+ PA++++ earns its legendary status in J-beauty circles. It delivers maximum-grade SPF 50+ PA++++ broad-spectrum protection through an unusually sophisticated 5-filter hybrid system — featuring premium UV filters like Tinosorb S and Uvinul A Plus that are simply unavailable in US-market sunscreens — at a price point that makes this genuinely accessible for daily use. The fragrance-free, alcohol-free water-gel formula feels like applying a hydrating lotion rather than sunscreen, dries down in seconds to a luminous, glass-skin finish, and doubles as an excellent makeup primer that truly eliminates the need for a separate base product. The 85% skin-beautifying formulation with Hyaluronic Acid, Glucosyl Ceramide, Mulberry Root Extract, and a comprehensive antioxidant botanical complex makes this more than a sunscreen — it's a skincare-first hybrid product in the best J-beauty tradition. The main limitations are the small 40g tube (stock up), the non-water-resistant formula (not for the beach or gym), and the FA-unsafe status. But as an everyday city sunscreen for dry, normal, combination, and sensitive skin types looking for maximum protection with skincare benefits and primer functionality, it remains one of the best-formulated, best-value sunscreens available worldwide.

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.

Awesome, I Understand!
