Product Summary
"COSRX - Natural BHA Skin Returning A-Sol - Korean Beauty Store" is effective for: Exfoliation, Moisturizing, Evens skin tone and Anti-aging

Ingredient callouts
- Exfoliating acids (glycolic acid 1.40% - 2.00% and lactic acid 2.60% - 3.80%). In this concentration, they will have a noticeable exfoliating effect. They can also have an anti-aging effect and stimulate collagen production in a long-run. Lactic Acid can also help to attract water to the upper layer (works as a humectant).
- Panthenol (pro-vitamin B5) at about 0.50% - 1.20% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
- Humectants (panthenol 0.50% - 1.20%, sodium hyaluronate 0.80% - 1.25%, lactic acid 2.60% - 3.80% and sodium lactate 3.30% - 4.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains glycolic acid.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: lactic acid.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
An alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid
An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
Evens skin tone
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: betaine salicylate, glycolic acid, lactic acid
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: betaine salicylate, glycolic acid, lactic acid.

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": lactic acid, sodium hyaluronate.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
