Vitamin D Booster: The biomimetic active ingredient that balances, strengthens, and revitalizes the skin

The Vitamin D Booster is an innovative active ingredient incorporated into SUNLIGHT SCREEN 50+. Inspired by skin physiology, it helps the skin reactivate its natural vitamin D production, even in the absence of UV exposure, while helping to preserve its balance, hydration, and vitality.

VITAMIN D, A KEY ELEMENT FOR SKIN BALANCE

Often associated with the sun, vitamin D plays an important role in several essential skin mechanisms, such as skin barrier balance, cellular cohesion, and hydration. Naturally produced by the skin under the action of UVB rays, it is essential for overall skin function. Over time, limited exposure or certain environmental factors such as pollution can weaken this balance.

Understanding the role of vitamin D also helps highlight the value of skincare designed to support its benefits for the skin.

This is precisely where the Vitamin D Booster comes in: helping the skin restore the conditions that support its balance and vitality.

THE VITAMIN D BOOSTER

The Vitamin D Booster is a biomimetic active ingredient inspired by the plant Lithops pseudotruncatella, a desert succulent from Africa known for its exceptional longevity.

Applied to the skin as part of the Vitamin D Booster, this biomimetic mechanism acts on the skin’s micro-environment to help the skin retain water more effectively, capture light more efficiently, and naturally promote vitamin D synthesis.

WHY USE THE VITAMIN D BOOSTER?

The skin’s natural vitamin D production can be influenced by various factors, such as lack of exposure or certain everyday environmental conditions.
The Vitamin D Booster therefore helps the skin support this production, even in the absence of UV exposure or when the skin is protected by sunscreen filters.
