Only 3 days using it and I'm impressed, my skin barrier is stronger and my acne is starting to fade quicker than the other formulas l've tried. I have sensitive skin and my redness has improved, I'm starting to fall in love 😍
WORTH THE HYPE! I’ve been using azealic acid for since 2021 and I swear it’s the best acne, post acne scar, and dark spot treatment out there. When I saw Anua come out with this, I had to get my hands on it cause I’ve been using ANUA for quite a while and it was fungal acne safe which was a huge plus for me! I’ve had a huge breakout problem in December and I’ve been using this serum since then and Show more
