For Skin's Sake - aiskinjourney review for Retinol Serum

I had extremely bad reaction and inflammatory acnes after using this (only use it 2x a week back then to avoid severe irritation). Like, my whole face was burning and I got cystic acnes all over. It might be because of the purging, but honestly it was tormenting me so I don’t use this anymore after using a third of the bottle.
