Lily D. ★★★★★ Oct 21, 2026

Dark spots on my cheeks have faded noticeably after about three weeks, and my pores look smaller around my nose. The texture is light and absorbs fast, so it layers fine under moisturizer at night.

William O. ★★★★★ Oct 20, 2026

I've been using this every other night for about three weeks, and the texture of my skin is finally smoother with fewer clogged pores. The mandelic acid feels gentle enough that I don't get the redness I've had with other exfoliating serums.

The dark spots on my cheeks from old breakouts are finally fading after about three weeks of nightly use. I love that it doesn't make my skin feel stripped or tight like other acne treatments.
