Hydra Synol® DOI

A Smart Lipophilic Skin Hydrator & Barrier Builder

Hydra Synol® DOI is a smart skin hydrator and barrier builder that intelligently provides optimum hydration based on skin moisture content/deficit. It works by stimulating Aquaporin-3, Tight Junction, Desmosomes and Epidermal Differentiating genes/proteins.

Isosorbied Dicaprylate clinically shown to be very effective in providing long-lasting (>48 hrs.) and controlled skin hydration.

Hydra Synol® DOI can also be used as a natural and biodegradable alternative to phenyltrimethicone to maximize hair shine.
