Great serum for sensitive acne prone skin
I used this serum daily in the am followed by 50spf sunscreen. I noticed a visible reduction in my acne scars and fewer breakouts from week 2. I cant recommend this enough for my fellow acne prone girls.
Verified Purchase
I'd recommend anyone to give it a try
Has really helped my acne! Pleasantly suprised. Didn't make it ALL go away but probably 50-60% so far. Having such a high concentration, idk how sensitive skin would react since my skin is weirdly tolerant to literally everything and anything I put on it, so probably beware if you have sensitive skin because even on my skin it stung slightly (but that's it).
It burned a little bit
[This review was collected as part of a promotion.] It burned a little bit at first but that went away with a few uses. I use it at night and put Cosrx hyaluronic acid cream on top of it. my skin wakes up clearer with a more even skin tone. I'm very happy with this product.
