Skin Diligent was founded on a simple idea: to create skincare safe enough for our loved ones—and powerful enough to make a real difference.

Our skincare range, based on science, epigenetics, and biotechnological innovation, is designed to sustainably preserve the skin's health and youthfulness. Clinically proven, subject to advanced testing against endocrine disruptors, and designed to activate longevity genes, it combines technical sophistication, visible effectiveness, and absolute safety.

Co-developed with scientists, biologists and ethnobotanists, our formulas are based on discoveries validated by science to act directly at the heart of cellular mechanisms according to the skin's needs.

Rooted in science and epigenetics, our treatments teach skin to better defend itself, slow aging, and sustainably preserve its youthful appearance. This is what we call the Cellular Fitness Program.

Skin Diligent is the first skincare brand to systematically test all of its formulas for estrogen-like endocrine disruptors, setting a new global standard for efficacy and safety.
