Good Genes 甘醇酸煥膚精華

Two weeks in and my forehead's texture has completely smoothed out—the glycolic acid really does cut through that congested, dull look. I only use it every other night and my skin's got this glow that wasn't there before.

My chin and jawline were covered in rough little bumps that no scrub could touch, and this glycolic acid is the only thing that’s smoothed them out in about three weeks. A tiny bit goes a long way, so the bottle feels like it’ll last forever for the price.

The first week my skin felt a bit tingly, but by the third use, that congestion and rough texture I've been dealing with finally started to smooth out. It's definitely a strong glycolic acid, so a little goes a long way, but the radiance it's brought back is worth it.
