HYDROLYZED CAMELLIA JAPONICA SEED OIL EXTRACT.

Engineered through hydrolysis, this ingredient cleaves larger lipid structures into smaller, more skin-permeable essential fatty acids (e.g., oleic, linoleic), polypeptides, and amino acids. This optimized molecular size facilitates deeper absorption, providing intense hydration and reinforcing the skin's natural barrier. It functions as a potent emollient, delivering nourishment without a heavy feel. Furthermore, it exhibits significant antioxidant capabilities, actively neutralizing oxidative stress. Research on its non-hydrolyzed counterparts suggests a broader spectrum of action, potentially encompassing the stimulation of type I procollagen synthesis, inhibition of MMP-1 activity, and stimulation of fibroblasts to enhance collagen production and improve elasticity. It also aids in reducing transepidermal water loss (TEWL) and boosting hyaluronic acid synthesis. Its anti-inflammatory properties are demonstrated by suppressing pro-inflammatory gene expression and inhibiting key inflammatory mediators like nitric oxide (NO), prostaglandin E2 (PGE2), and TNF-α.
