Carter ★★★★★ Oct 22, 2026

I’ve had this dark spot on my cheek for months, and after using this serum for a little over a week, it’s noticeably lighter. The fact that it calms my breakouts while firming my skin makes it an effortless part of my evening routine. Definitely seeing smoother texture and a more even tone.

Lucy ★★★★★ Oct 21, 2026

After just two weeks, those stubborn post-acne marks on my chin are noticeably lighter. The serum absorbs quickly without feeling sticky, so it fits perfectly into my nighttime routine.

Abigail Z. ★★★★★ Oct 20, 2026

Used this serum for about three weeks and the texture around my chin feels noticeably smoother. The tranexamic acid seems to be really helping with the dark spots from old breakouts too, and my skin looks firmer in the morning.
