I almost didn’t buy this because my skin is ridiculously sensitive and anything with lactic acid has historically been a hard no for me. I have a history of rosacea, and exfoliating products usually make my skin very angry but I’m so glad I gave this a try!
I honestly don’t know how to explain it other than this stuff feels like magic. I put it on at night and wake up with noticeably different skin. Smoother, brighter, more even, and just healthier-looking overall. I know “I woke up with different skin” sounds dramatic, but that’s genuinely been my experience. Every. Single. Time.
If you’re someone with sensitive skin who has been hesitant to try something like this with lactic acid, I was right there with you…but this has been one of the most pleasant skincare surprises I’ve had in a long time. This product is absolutely amazing.

I’ve tried a lot of vitamin C’s. I swear by this one. Every time people talk about skincare I recommend this. It’s gotten rid of my dark hyper pigmentation spots on my cheeks.
