Ingredient breakdown

INGREDIENTS

Glycolic Acid 0.1%Proven

The most researched and well-known AHA exfoliant. At this low concentration, it works as a gentle exfoliant and pH adjuster rather than an intensive peel.

  • Function: Breaks down bonds between dead skin cells for gentle exfoliation
  • pH Dependent: Works best at pH 3-4 (this product: 3.85-4.0)
  • Molecular Size: Smallest AHA molecule for better penetration
Low concentration (0.1%) makes this suitable for daily use and beginners, but won't provide strong exfoliation effects.

Betaine Salicylate 0.1%Promising

A gentle BHA alternative combining salicylic acid with moisturizing betaine. Popular in K-beauty due to South Korean regulations limiting pure salicylic acid use.

  • Function: Oil-soluble exfoliant that penetrates pores to remove sebum
  • Optimal pH: Most effective at pH 3.8-4.2 (matches this formula)
  • Gentleness: Less irritating than pure salicylic acid, ideal for sensitive skin
Gentler than pure salicylic acid, making it suitable for sensitive skin types.

Pyrus Malus (Apple) Fruit Water 10%Natural

Natural source of alpha hydroxy acids derived from apples. Provides gentle exfoliation while delivering vitamins and antioxidants.

  • Source: Natural fruit water containing malic acid (an AHA)
  • Benefits: Hydration, vitamins, and mild exfoliation
  • Skin Feel: Refreshing and non-irritating

Salix Alba (Willow) Bark Water 10%Natural

Natural extract rich in salicylates, the precursor to salicylic acid. Known for soothing and mild exfoliating properties.

  • Source: White willow bark, a natural salicin source
  • Properties: Anti-inflammatory, soothing, mild exfoliation
  • Traditional Use: Used for centuries for skin-soothing benefits

Panthenol (Pro-Vitamin B5)Proven

A well-researched moisturizing and skin-conditioning ingredient with wound-healing and anti-inflammatory properties.

  • Function: Humectant that attracts and retains moisture
  • Benefits: Soothes irritation, supports skin barrier repair
  • Safety: Extremely well-tolerated by all skin types

AllantoinProven

A super common soothing ingredient that helps calm and protect the skin. Often added to products with active ingredients to reduce potential irritation.

  • Function: Skin-soothing and protective agent
  • Benefits: Promotes wound healing, reduces irritation
  • Source: Found naturally in comfrey plant, usually synthetic in cosmetics

Frequently asked questions

FAQ

No. COSRX officially recommends avoiding this product during pregnancy and breastfeeding. While the AHA/BHA concentrations are very low (0.1% each), the brand takes a cautious approach. Consult your healthcare provider for personalized advice on safe skincare during pregnancy.

Yes! This toner is fungal acne safe. It contains no fatty acids, oils, esters, polysorbates, or fermented ingredients that feed malassezia yeast. The minimal 11-ingredient formula is free from common fungal acne triggers, making it an excellent choice for those prone to pityrosporum folliculitis.

COSRX recommends NOT using this toner simultaneously with other acids (AHAs, BHAs), retinols, or vitamin C to avoid over-exfoliation and irritation. Instead, alternate usage - for example, use this toner in the morning and retinol at night, or use vitamin C on different days. If you want to layer, wait at least 20-30 minutes between products.

This toner is excellent for oily, combination, and acne-prone skin types due to its oil-free, non-comedogenic formula. It's also suitable for sensitive skin beginners to chemical exfoliation thanks to the very low acid concentrations (0.1%). Those with very dry skin may find it slightly drying and should follow with hydrating products. Not ideal for mature skin seeking strong anti-aging effects.

Due to the gentle, low-concentration formula, results are subtle and gradual. Most users notice smoother skin texture within 1-2 weeks. Improved clarity and reduced congestion typically appear around weeks 3-4 with consistent daily use. Don't expect dramatic peeling or overnight transformation - this is a maintenance product, not an intensive treatment.

Apply immediately after cleansing (double cleanse if wearing makeup/sunscreen). This toner should be used before any other toners, essences, serums, or moisturizers. Its low pH (3.85-4.0) helps prep your skin for better absorption of subsequent products and makes pH-dependent actives work more effectively. Always finish with sunscreen in the morning.

No, this toner has a comedogenic rating of 0/5. It's oil-free, silicone-free, and contains no pore-clogging ingredients. In fact, it's designed to help prevent clogged pores by gently exfoliating dead skin cells and excess sebum. It's safe for acne-prone skin and won't cause breakouts.

The product has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight to maintain potency. The 150ml bottle typically lasts 2-3 months with twice-daily use. If you notice changes in color, smell, or texture before 12 months, discontinue use.

— Skincarisma verdict
4.2 / 5 ★★★★☆

Verdict: The COSRX AHA/BHA Clarifying Treatment Toner is an excellent entry-level exfoliating toner that prioritizes gentleness over dramatic results. With only 0.1% of each acid, it's more of a pH-adjusting prep toner than a true exfoliant. Perfect for beginners, sensitive skin, and those seeking a minimal, fungal acne-safe formula. However, if you want visible exfoliation, skin brightening, or anti-aging benefits, you'll likely need a product with higher acid concentrations. Best used as a daily maintenance step to keep pores clear and enhance the effectiveness of your other actives.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

question
lightbulb What is the Ingredient Safety Breakdown?

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.
