Mandelic Topical Acid 12%

The niacinamide in this formula really pulls its weight—my post-blemish marks are visibly lighter after three weeks of nightly use. It’s gentle enough that I don’t get that stinging sensation like with other acids, which is a huge win for my sensitive skin.

Dark spots on my chin have faded noticeably after three weeks of nightly use, and the texture feels smoother without any irritation. The mandelic acid plus niacinamide combo is doing exactly what it claims—gentle enough for my sensitive skin but actually effective.

I’ve been using this nightly for about three weeks and the dark spots from old breakouts are finally starting to fade, which nothing else has managed. The niacinamide keeps my skin from feeling stripped, even though it’s a 12% acid. Just wish the bottle were bigger.
