It promotes a soft, smooth surface feel and supports skin comfort while helping condition the upper layer.

Where it helps

Concerns Allantoin addresses

  • Hyperpigmentation

    Across Fitzpatrick III–V skin tones — the majority of darker skin tones — the most common consultation is the same: the patch on the cheekbone that did not fade. Melasma, post-inflammatory hyperpigmentation, the marks that follow acne and friction. The pattern is photoresponsive, the mechanism is mapped, and visible improvement is reachable with consistent care. The Whitepurity range is built for that work — Alpha-Arbutin for stable tyrosinase inhibition, Niacinamide-led brightening, and the SPF discipline that decides whether any of the rest will hold.

  • Sensitivity

    If you have sensitive skin, you have probably been told it is in your head — by a product that says "gentle" on the label, by a friend whose skin tolerates everything yours cannot, sometimes by a professional who could not find a visible cause for the symptoms. It is not in your head. The mechanisms are measurable, the biology is mapped, and the care that follows from understanding them is what the Sensimed range was built around.
