The INKEY List Tranexamic Acid Serum ingredients: is it worth it?
A credible but modest dark-spot serum—not the powerhouse its brightening language suggests.

READ MORE
The 3.4/5 efficacy score comes mainly from disclosed 2% tranexamic acid in position five, with humectants high in the formula supporting hydration. Ascorbyl glucoside is a weaker, indirect vitamin C derivative than direct ascorbic acid, the product does not disclose pH, and the acai extract should not be treated as a clinically meaningful treatment driver. The uncomplicated gel-emulsion base is well designed for daily use, but the formula lacks the concentration and evidence profile needed for a top-tier pigment treatment.
