Vitamin B12: The unsung hero that takes care of your skin

We hear a lot about vitamin C, vitamin E, or retinol. But vitamin B12 in cosmetics? It's still a confidential active ingredient, little used in mainstream formulas — and that's precisely what attracted us. At Kosmorebi, we like ingredients that really do something, even when they're not yet making headlines.

What exactly is vitamin B12?

Vitamin B12, or cobalamin, is a water-soluble vitamin essential for the proper functioning of the body. We use cyanocobalamin, the most stable form of vitamin B12, which guarantees its effectiveness throughout the product's shelf life.

Applied to the skin, it acts on several levels:

Its benefits for the skin

• Soothing and anti-inflammatory: Vitamin B12 is known for its soothing properties. It helps reduce redness, irritation, and inflammatory reactions, making it a particularly interesting active ingredient for sensitive or reactive skin.
• Regenerating: It plays a role in cell renewal by supporting the synthesis of DNA in skin cells. Better skin renewal means smoother, more radiant, and younger-looking skin.
• Moisturizing: By strengthening the skin's barrier function, it helps limit transepidermal water loss and maintain good skin hydration.
• Antioxidant: It protects cells against oxidative stress, thus complementing the action of other antioxidant active ingredients present in our formulas.

Why did we choose it for our Damask Rose micellar foam?

Our Damask Rose micellar cleansing foam is designed for sensitive, reactive, or dull skin. Vitamin B12 fits perfectly into this philosophy: it enhances the soothing action of Damask rose and centifolia rose hydrolat, complements probiotic active ingredients that balance the microbiome, and amplifies the effect of Alpine rose extract.

This extract has a senolytic action: it eliminates zombie cells — these non-functional fibroblasts that, instead of being naturally eliminated and replaced, persist in the skin and clutter it. By eliminating them, it makes room for new young and functional fibroblasts, capable of producing collagen and elastin. It is a truly innovative approach to skin aging, which acts on the causes rather than on the symptoms.

The result: a cleanse that not only removes impurities but also takes care of your skin with every use.

The most effective active ingredients are not always the best known. At Kosmorebi, we choose them for what they do — not for what they sell. 🌿
