Science

Mechanism of Action

PRUNUS SERRULATA LEAF CELL EXTRACT delivers a comprehensive array of benefits through its rich composition of flavonoids and polyphenols. It functions as a powerful antioxidant, actively safeguarding skin cells from oxidative stress and environmental aggressors, including UV radiation. The extract further exhibits anti-inflammatory properties, effectively diminishing skin irritation and redness by modulating key inflammatory mediators such as nitric oxide, interleukin-6, and tumor necrosis factor-alpha. It enhances skin hydration, supports the natural cell renewal process for a smoother texture, and reinforces the skin's protective barrier. Moreover, it offers skin brightening by inhibiting tyrosinase, an enzyme critical for melanin synthesis, thereby reducing hyperpigmentation and promoting a more even tone. Its anti-aging potential is attributed to the inhibition of the glycation process, which is implicated in the degradation of collagen and elastin, thus aiding in the reduction of fine lines and wrinkles.

Stability

This extract exhibits optimal stability within a narrow acidic pH range of 4.2 to 4.5, with observed degradation of anthocyanins at neutral or basic pH levels. Its stability can be enhanced by the inclusion of organic acids such as citric, malic, tartaric, and succinic acids. Degradation may occur in the presence of certain metal ions (excluding tin and iron), ascorbic acid, and oxygen. The ingredient is also sensitive to light. For optimal preservation, store in a cool, dry place, shielded from direct sunlight.
