Niacinamide-and-transexamic serum for dark spots; light, stackable, and under-makeup friendly.
What the community says
A light, slightly gel-like serum people stack with tret and sunscreen for dark spots, redness, and a bit of pore refinement. Redditors like the texture and layering, but pigmentation results are mixed and one user felt spots worsened.
