What it is
Healthy skin is moist, smooth, and less prone to problems like breakouts. This is due to an ideal balance of the microbiome (a diverse collection of resident bacteria on the skin). Enrich Bio Serum focuses on Staphylococcus epidermidis, a beneficial bacterium that keeps skin healthy. By supplementing with prebiotics, it boosts the skin's natural balance and aims to create healthy skin. Use it as a pre-serum immediately after washing your face. It has an elegant scent of geranium and Damask rose.

We're working on rolling out prepaid duties for more countries soon.
