Panthenol (provitamin B5): the skin's restorative ally

Also known as provitamin B5, it has nevertheless been the subject of numerous studies, and its reputation as a ally for sensitive skin is well established.

Panthenol moisturizes, repairs, and soothes the skin: it is a skin-comforting active ingredient that is particularly beneficial for dry, sensitive, or stressed skin. Here's what it actually does, and who it's intended for.

What is panthenol?

Panthenol is the provitamin form of vitamin B5 (pantothenic acid). Once applied to the skin, it converts to vitamin B5, which plays a role in numerous cellular processes. It is a humectant—that is, a molecule capable of attracting and retaining water—and is known for its excellent tolerability.

This gentleness, combined with its proven effectiveness, explains why it is found in a wide variety of skincare products, from restorative creams to products designed for sensitive or irritated skin.

It repairs: scientific data show that it supports the repair of the skin barrier and aids in skin regeneration, making it an ideal active ingredient for damaged or fragile skin.

It also has soothing and anti-inflammatory properties: it helps reduce redness, irritation, and discomfort, and studies have shown that it improves barrier repair and reduces inflammation following skin damage. As an added bonus, it softens the skin and enhances the feeling of comfort.

Thanks to its remarkable tolerability, panthenol is suitable for all skin types and is particularly beneficial for dry, sensitive, reactive, or irritated skin. It is also an excellent choice for skin that is temporarily stressed, such as after exfoliation, sun exposure, or the introduction of a more potent active ingredient.

It is, of course, a key ingredient in skincare products designed to repair, soothe, and restore the skin's comfort, often working in synergy with other complementary active ingredients.
