Tranexamic Topical Acid 5%

The texture is surprisingly light for a 5% acid serum, sinks in fast without any stickiness. Three weeks in and the stubborn sun spots on my cheekbones have definitely lightened, and the niacinamide in it seems to help with overall redness too.

I've been using this every night for about a month and the dark spots on my cheeks are noticeably lighter. The licorice root and niacinamide combo feels gentle, no stinging at all, and I love that the serum absorbs without leaving that sticky residue.

The dropper makes it easy to apply just a few drops on my sun spots, and after three weeks they're noticeably lighter. It's a bit sticky for a minute, but that fades once it sinks in.
