Product Summary
"COSRX - AHA 7 Whitehead Power Liquid - Best Korean Beauty Store" is effective for: Anti-aging, Exfoliation, Anti-blemish, Moisturizing and Evens skin tone
Ingredient callouts
- A good concentration of Niacinamide (2.30% - 3.50%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
- Exfoliating acids (glycolic acid 4.70% - 7.10%). 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.
- An effective concentration of Panthenol (pro-vitamin B5) - about 0.50% - 1.10%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
- Humectants (sodium hyaluronate 0.35% - 0.80% and panthenol 0.50% - 1.10%). 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, niacinamide.
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
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production

Exfoliation
What does the product description say?
Cosrx AHA 7 Whitehead Power Liquid helps to rid the skin of whiteheads while working to improve skin complexion.

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: glycolic acid.

Moisturizing
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": sodium hyaluronate, butylene glycol.
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: niacinamide, panthenol
