Zinc Zinc PCA
Zinc PCA (the zinc ester of pyrrolidone carboxylic acid) is a versatile cosmetic ingredient combining the mineral zinc with the skin's natural moisturising factor (NMF). It works on multiple fronts for oily and problematic skin — it regulates sebaceous gland activity by inhibiting 5-alpha-reductase, the enzyme responsible for sebum overproduction. It has strong antibacterial and anti-inflammatory properties, helping heal acne lesions and prevent new ones from forming. It also supports epidermal regeneration and strengthens the skin's hydrolipid barrier. An ideal ingredient for caring for oily, combination and acne-prone skin, as well as skin with enlarged pores and a tendency to shine.
