Meet Dr.Althea 15% Niacinamide Purity Serum

Dr.Althea 15% Niacinamide Purity Serum offers a clean, vegan formula inspired by Korean skincare. It combines 15% Niacinamide with Zinc PCA and the MELACUT Complex to support brightness, moisture, and a balanced feel for daily use.

Its lightweight, fast-absorbing texture layers smoothly under moisturizers and sunscreen, delivering a refreshing finish without the stickiness that can come with richer serums. The vegan formula uses only EWG Green Grade ingredients and is free from artificial colors and scents, appealing to those who prioritize cleaner formulations.
