skin exfoliation | Skin Alphabet | 10% gluconolactone | acid-in-lecithin


I don’t know if this is a problem of the package itself or the shipping company is to blame, but my bottle had a leakage problem at first, so I lost part of the product. That’s why I give it 3 stars. But for the products itself, I think it is ok. At least it works.


My skin feels so soft after using this. It cleans it, refreshes it, and leaves it so dewy! This is a key part of my night routine. Everyone keeps complimenting my skin, so I spread the word about this amazing acid. I love it! 💗


None of the products I’ve used before has helped me get rid of my stubborn blackheads in a easiest way than this one, I’ve used it for less than a week and the fact that I was able to see the results so fast has made me confident about this brand! I’m obviously gonna try a bunch of skincare products from skin alphabet!


My skin has a lot of texture and hyperpigmentation, it is also sensitive, so you can tell I got the winning combo, lol. This chemical exfoliation does wonders. Is effective, but also gentle. I have seen my texture reduced, and also my hyperpigmentation, without making my sensitivity worse. I recommend its nightly use. And of course, start using it one time a week, and increase it if you don’t have any problem.


I bought a bottle of this for my mom, and another for my aunt. They love it! We use it for different purposes (me, to get rid of blackheads on my chin) and them to get rid of flakey skin, and it works perfectly good.
