Test on a small area first. Not suitable for sensitive, peeling, or compromised skin. Discontinue if irritation occurs.
Ingredient breakdown
INGREDIENTSLactic Acid 10%Proven
An alpha hydroxy acid (AHA) derived from milk that exfoliates by dissolving the bonds between dead skin cells. Gentler than glycolic acid due to its larger molecular size, making it ideal for sensitive or dry skin.
- Exfoliation: Removes dead skin cells to reveal brighter, smoother skin
- Hydration: Acts as a humectant, attracting moisture to the skin
- Barrier Support: Studies show lactic acid helps skin produce ceramides
- Microbiome: Research indicates support for beneficial skin bacteria
Sodium Hyaluronate Crosspolymer 2%Proven
A crosslinked form of hyaluronic acid that provides sustained moisture retention. Can hold up to 1000x its weight in water, keeping skin hydrated and plump.
- Hydration: Attracts and retains moisture in the skin's upper layers
- Extended Release: Crosspolymer form provides longer-lasting hydration
- Barrier Support: Helps prevent transepidermal water loss
Tasmannia Lanceolata Fruit/Leaf ExtractPromising
Tasmanian pepperberry extract contains polygodial, a compound with anti-inflammatory and antioxidant properties. Helps reduce irritation and redness associated with acid exfoliation.
- Anti-Inflammatory: Reduces visible signs of inflammation and sensitivity
- Antioxidant: Protects against environmental damage
- Natural Color: Gives the serum its slight amber tint (varies seasonally)
GlycerinProven
A powerful humectant naturally present in skin. Studies show glycerin is more effective than many other moisturizing ingredients at maintaining hydration.

Frequently asked questions
FAQYes, lactic acid is broadly considered safe during pregnancy and breastfeeding. Unlike retinoids or high-concentration salicylic acid, lactic acid has a larger molecular size that limits systemic absorption. Many dermatologists recommend lactic acid as a pregnancy-safe alternative for chemical exfoliation. However, always consult your healthcare provider before using any new skincare products during pregnancy.
Yes, this product is fungal acne safe. The formula is free from fatty acids, oils, esters, polysorbates, and fermented ingredients that can feed malassezia yeast. Multiple ingredient analyzers confirm it contains no fungal acne triggers, making it suitable for those prone to pityrosporum folliculitis.
Do not use lactic acid in the same routine as retinoids, pure/ethylated vitamin C, other direct acids (like glycolic or salicylic), peptides, or EUK 134. These combinations can cause irritation, compromised skin barrier, or reduced efficacy. You can alternate days (e.g., lactic acid one night, retinol the next) or use them at different times (vitamin C in AM, lactic acid in PM).
This product is particularly excellent for dry and combination skin types because lactic acid acts as a humectant while exfoliating. It's also great for acne-prone skin due to its non-comedogenic, fungal acne-safe formula. Those with sensitive skin may want to start with the 5% version first. Oily skin types can use it but may prefer stronger glycolic acid formulas for deeper exfoliation.
You may notice an instant glow after the first use. Texture improvements typically appear within 1-2 weeks. Visible brightening and fading of dark spots usually takes 4-6 weeks of consistent use. Maximum results for hyperpigmentation and fine lines are typically seen at 8-12 weeks. Consistency and daily sunscreen use are key for optimal results.
Apply in the PM only, after cleansing and toning (if using a water-based toner), but before serums, moisturizer, and facial oils. The order is: Cleanser → Toner → Lactic Acid → Serum → Moisturizer. Always follow with SPF 30+ the next morning, as AHAs increase sun sensitivity.
No, this product has a comedogenic rating of 0/5. It's water-based, oil-free, silicone-free, and contains no pore-clogging ingredients. In fact, by promoting cell turnover and clearing congestion, lactic acid can actually help minimize the appearance of pores and prevent clogged pores.
The Period After Opening (PAO) is 12 months. Once opened, use within one year for best efficacy. Unopened, The Ordinary products have a shelf life of 3 years from manufacture date. Store in a cool, dry place away from direct sunlight to maintain product integrity.
Verdict: The Ordinary Lactic Acid 10% + HA delivers exceptional value as an effective, gentle chemical exfoliant. At under $10, it rivals products costing 10x more (looking at you, Sunday Riley Good Genes). The hydrating formula makes it ideal for dry skin types, while its fungal acne-safe and non-comedogenic profile suits acne-prone skin. The Tasmanian pepperberry adds anti-inflammatory benefits that set it apart from basic lactic acid formulas. Minor drawbacks include the dropper design and watery texture, but these don't diminish its outstanding performance. For anyone seeking brighter, smoother, more even-toned skin without breaking the bank, this is a skincare staple worth having in your routine.

Understanding Simple Alcohols
Alcohol ingredients are widely used in cosmetics and come in different types. For the most part alcohols are not problematic at all. However one type of alcohols, simple alcohols can be quite drying to the skin because it evaporates very quickly. This can cause irritation which can also lead to other skin complications. These alcohols should never be used alone on your skin, but combined with other cosmetic ingredients, they are normally without issue.

Silicone-Free
Silicone-Free
Understanding Silicones
If you've ever used a skincare, makeup or beauty product that's made your skin look and feel smoother tempoarily - it's likely contained Silicone. They are a popular class of ingredients found in cosmetics due to their smooth, soft, easy-to-spread and smooth properties that help creates an artificial layer/barrier on top of skin or hair (commonly found in conditioners).
For the same reasons they are popularly used, they are also commonly avoided. Anecdotally, many individuals have reported that Silicones cause/excerbate breakouts, irritation, cause a feeling of skin being unable to breathe, cause clumping of cosmetic products and find it difficult to wash off. As a result, those who find them problematic are avoiding them and increasingly, cosmetic companies are avoiding them as well.
If you have had bad experiences with Silicones in the past, or suspect they are problematic then look out for the tick on the Silicone-free label.
Disclaimer
The Silicone-free label only includes the most common Silicone ingredients that have indentified been reported by individuals that could potentially cause issues.
These include: Amodimethicone, Behenoxy Dimethicone, Bis-Aminopropyl Dimethicone, Cetearyl Methicone, Cetyl Dimethicone, Cyclomethicone, Cyclopentasiloxane, Dimethicone, Dimethicone Copolyol, Dimethiconol, Methicone, Phenyl Trimethicone, Phenyl Trimethicone, Stearoxy Dimethicone, Stearyl Dimethicone, Trimethylsilylamodimethicone.
Note, that this does not include all ingredients part of the Silicone class of ingredients.
EU Allergen-Free
EU Allergen-Free
Understanding the Identified Contact Allergens
The EU's Scientific Committee on Consumer Safety (SCCS) has identified and established 26 cosmetic ingredients that are likely contact allergens (potential to cause skin allergies) as demonstrated in clinical or epidemiological studies. The EU's SCCS have recommend cosmetic companies to disclose them on the labels if used and in cases where the concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products, then they must be labelled.
Look out for the tick on the EU-Allergen free label to know your cosmetic is free from any of the 26 identified cosmetic ingredients.
For more information regarding the EU's Scientific Committee on Consumer Safety, please visit their official website.
Disclaimer
The EU Allergen Free label is for the 26 ingredients identified by the EU SCCS and products will be only flagged if a suspected ingredient is on it's ingredient list. It is possible for cosmetics to contain one of the suspect ingredients without it appearing on the ingredient list due to it not reaching the concentration threshold to disclose it and cosmetic manufacturers choice to not disclose it.
Also note, the EU Allergen Free label is not personalized for your own allergies you may have and it does not constitute as medical advice.

Fungal Acne (Molassezia) Safe
Understanding Fungal Acne (Pityrosporum Folliculitis/Malassezia Folliculitis)
Pityrosporum Folliculitis/Malassezia folliculitis or simply known as Fungal Acne is a persistent acne-like condition that commonly responds poorly to traditional acne-treating methods. Unlike most cases of Acne where bacteria is the culprit, Fungi is the culprit of Fungal Acne (Hence the name!). There are certain classes & groups of ingredients that have been shown to promote and feed the growth of the Fungal Acne, Fungi such as fatty acids, oils, esters, polysorbates and fermented ingredients.
For more information regarding Fungal Acne, please visit Simple Skincare Science (f.c) - #3 of our Recommend Skincare Resources for an amazing comprehensive guide!
Please Read: How to use the Fungal Acne (Malassezia) Label
At SkinCarisma, we've done our best to identify as many ingredients as possible but note the fungal-free label may not be 100% accurate due to the complexconditions and combination of ingredients that malezzeria can thrive on.
Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.
As a result, please note this is only an experimental label that can be best used to possible identify problematic products you have used in the past. It is in no way a perfect identifier nor a predictor in whether or not it will exacerbate or cause fungal acne. It will continue to be worked on as more information and research comes to light.
If you find any ingredients you believe should be included, please email us at snails@skincarisma.com.
Disclaimer
Due to the lack of substantial research into this area it is very likely there are other ingredients and class/groups of ingredients that could feed Fungal Acne which have not been indentified.
The Fungal-Safe label does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
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.
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.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

Pro Tip Alert!
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!

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.
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.
