The underestimated moisture booster: Anhydroxylitol explained
Modern skincare increasingly relies on highly effective ingredients that specifically improve skin health and strengthen the natural protective function. One such active ingredient is Anhydroxylitol – a moisturizing active substance that can have an excellent effect, especially in combination with hyaluronic acid. But what exactly is Anhydroxylitol, how does it work on your skin, and in which product from the KÖSMETIK range is it used?
What is anhydroxylitol?
Anhydroxylitol is a derivative of the sugar molecule xylitol and belongs to the group of sugar alcohols known for their moisturizing properties. In skincare, anhydroxylitol is especially valued for its ability to improve the skin's water-binding capacity and reduce moisture loss through the skin surface.
Together with xylitol and xylitylglucoside, it often forms a moisture-regulating active ingredient complex that replenishes the skin's water reserves, strengthens the barrier function, and promotes water transport between the skin layers. The result: your skin feels smoother, plumper, and visibly more hydrated.
The effect of anhydroxylitol on the skin
Anhydroxylitol acts on multiple levels:
ü Moisture retention: It supports the skin's ability to store moisture while simultaneously preventing excessive evaporation of water.
ü Strengthening the skin barrier: Through improved hydration, the skin barrier is strengthened – a crucial factor for healthy, resilient skin.
ü Optimization of skin appearance: Well-moisturized skin appears smoother, finer, and more radiant – dryness wrinkles can be visibly reduced.
ü Synergy effects with hyaluronic acid: In combination with hyaluronic acid, anhydroxylitol can unfold its effect even more efficiently, as both substances address different mechanisms for moisture binding.
How to sensibly integrate Anhydroxylitol into your care routine
Products containing Anhydroxylitol are suitable for all skin types, especially dry, sensitive, or mature skin. Pay attention to the following points when using:
1. Thoroughly cleanse your skin before applying a serum or care product with Anhydroxylitol.
2. Use the product daily, ideally morning and evening, to achieve a lasting care effect.
3. Combine it with a richer care product or sun protection if needed to optimally nourish and protect your skin.
