HOME COSRX AHA 7 Whitehead Power Liquid

Are you looking for an AHA liquid with an exfoliating effect that counteracts impurities? The alcohol-free COSRX AHA 7 Whitehead Power Liquid is effective in combating acne thanks to 7% AHA (glycolic acid), but does not dry out the skin. Therefore, it is suitable for all skin types, including dry skin. The alpha hydroxy acid (AHA) used comes from Pyrus Malus water, which is extracted from malic acid instead of plain mineral water to maximize exfoliating and brightening benefits without any irritation. The exfoliating effect of AHA ensures that dead skin cells and excess sebum are gently removed. The result is a clear, radiant complexion. For use during the daytime, follow with a broad-spectrum sunscreen rated SPF 30 or higher.

  • Pyrus Malus (Apple) Fruit Water is high in antioxidants to protect the skin from free radicals, and to help it maintain its youthful elasticity.
  • Glycolic Acid has antibacterial and antioxidant effects, which help to improve the skin's appearance while stimulating collagen growth.
  • Niacinamide helps build skin cells while also protecting them from environmental stresses, such as sunlight, pollution, and toxins.
  • Panthenol helps to improve skin's hydration, elasticity, and smooth appearance.

    100 ml


    1. Spread some product on clean hands or cotton pad and apply on face, tapping softly with fingertips to absorb. 2. Only after FULL absorbing, use other essence and cream and the next morning do not forget to use sunscreen. * If you feel severe stimulation or your purpose is removal of whitehead and sebum, wash off the product after 4 to 5 minutes with lukewarm water.

    Very good product

    Very good! A bit tingling the first times i used it, so let your skin get used to it slowly, but now i use it 3 times a week and my skin feels much clear and even!

    Nice but takes tume to work

    For some reason my first review didn't make it. I like this product, it does what it says but it takes some time. I wouldn't recommend it for sensitive skin though. M,y skin reacted well but I only use it every other day. It finally made some deep under the skin pimples go away.

    Works, but takes time

    I bought this to combat some pimples deep under the skin that just won't dissappear. I have non-sensitive oily and acneprone skin. This works well for me, i use it every other day. I had no problems with skin irritations whatsoever but since my acne is not that bad, I don't want to use it too much. It takes a while to work though, so patience!

    DON'T RECOMMEND for sensitive skin

    I have dry, sensitive and acne prone skin. Since I have problems with whiteheads and acne, I wanted to give this product a chance. However, it did NOT work for me AT ALL. I started using it once a week. Immediately after putting it on with a cotton pad, my skin started to get irritated and VERY red, almost like I was sunburnt. But the worst thing about this is that my skin STAYED like that for about two days. I read online that this can happen with AHAs and the more you use it, the less irritated your skin will be. I have to say that this is true, as my skin calmed down quicker the more I used it. I also have to admit that my skin felt very nice the next day, it just lookt horrible, like it was burnt. I decided that this product is not for me and changed to another AHA that is less concentrated (by Whishtrend Mandelic Acid), which ended up working better for me. A lot of people seem to like this product, but if you have very sensitive skin, you might want to start with something less concentrated.

    J'utilise ce produit tous les soirs sur la totalité de mon visage et il a vraiment aidé à calmer mes imperfections et affiner mon grain de peau. Je n'oublie pas de mettre une protection solaire le lendemain pour protéger mon visage au maximum.

    Smoothest skin

    I noticed an instant difference the first few days I used this product. My pores have got a lot smaller and my skin over all super smooth. I apply about 3 pumps of this liquid with a cotton round every night. Make not to use your bare fingers to put it on because it might irritate them (they get flakey).

    Very Good Treatment

    Start slow since it may cause irritation if you never used it before. It helped to lighten pigments and overall improve texture.

    Nightly miracle worker

    I have been using this little gem for some time now and wow did it help clear up my skin, I don't get blemishes often now and when I do they heal up super fast. I like to use this at night only under a good sleeping pack or moisturizer.

    En alternance avec le BHA, ces deux produits font des p'tites merveilles pour moi. Je ne les utilisent pas chaque jour pour ne pas sensibiliser ma peau, mais en cure de temps à autre, ils sont top
