SKINĒDIT PARIS · Food supplements for skin and hair
Skin losing firmness, persistent dark spots or hair that feels less dense? Discover three French-made oral formulas, each developed around a different concern.
Choose your formula, then your supply duration.

A softer contour, a mark that lingers, hair that feels less dense: these changes are personal long before they become measurements. SKINĒDIT starts with what you actually notice, then looks deeper for the biology that can help explain it.
Beauty becomes more useful when desire and understanding can live together.

The SKINĒDIT system
AGELESS addresses structural longevity. RADIANCE is devoted to complexion clarity. REVIVAL explores follicular longevity. Three formulas remain distinct, even when brought together in one daily ritual.
An evaluation of a complete formula is different from a study of one ingredient. Here is the evidence behind each protocol, with its scope kept clear.
Of the 32 women who completed the independent AGELESS evaluation, 96.9% reported firmer or more elastic skin at day 90. Participant-reported outcome; individual results vary.
BELIGHT³™ has human ingredient evidence including two randomized trials read at 12 weeks. This is ingredient-level evidence, not a finished-product RADIANCE trial.
Cynatine® HNS has a 90-day randomized, double-blind, placebo-controlled oral ingredient study in 50 women. This is not a finished-product REVIVAL trial.
Study summaries are intentionally concise here. Methods, evidence levels and limitations are developed in the protocol pages and Intelligence.

Why stop at the surface when a face, a complexion and hair are shaped by deeper biology and by time? SKINĒDIT was created to follow those questions with precision — and to formulate only when the science gives us a reason to.
