The Ordinary Lactic Acid 5% + HA 15 ingredients
Holy grail for real. This stuff works instantly overnight to sooth acne and balance skin tone/texture. Everytime I do some damage picking at my skin, this serum basically undoes it all. Fantastic for maintenance whilst purging acne, I use this in rotation with the inkey list BHA serum and they have resurfaced and evened out all my fungal acne, going to move onto the 10% for clearing up my scars Show more
🤍 been using this for 2 years now, and i've really seen significant changes in my skin—especially with hyperpigmentation and texture ♡ however, it can be a bit irritating since i have sensitive skin, and it feels a little harsh when i combine it with the niacinamide 10% + zinc from the ordinary too. so, on my heavier days where my skin is extra sensitive, i skip this serum and just use moisturizer Show more

This peeling is effective, but it is quite harsh and sometimes irritates the skin.
not sure it really works
the skin does feel fresh and clean afterwards, but it dried my skin very much.. im not really sure its a legit exfoliator. a lot of sketchy ingerdients...
