This peel serum Is amazing! For this being at home peel, it is very gentle and has some very pure and simple ingredients. This serum contains retinol in addition to the AHA (glycolic acid), and also has cucumber, chamomile, green tea, and glycerin for hydration. I am obsessed and use this 1-2x a week for about 3-4 minutes. My skin is much more bright, and I noticed that some of my acne scars are beginning to fade. I have very sensitive skin, and really enjoy this at home peel serum. Oh, and this product is fragrance free, and is also cruelty free!
