Active ingredient
Zinc PCA
INCI · Zinc PCA
Zinc PCA pairs the humectant PCA backbone with zinc, giving it a dual surface-balancing and moisture-attracting character. It is a useful choice in formulas for combination or shine-prone skin, where a balanced, comfortable surface is the goal.
Mechanism in detail
What Zinc PCA does
Its PCA fraction attracts water while zinc contributes a surface-balancing role for a more comfortable finish.
Where it helps
Concerns Zinc PCA 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.
