LITCHI CHINENSIS PERICARP EXTRACT.

Valuable CAS 91722-81-5 / SKIN CONDITIONING

Litchi Chinensis Pericarp Extract, derived from the nutrient-rich peel of the litchi fruit, is a potent botanical ingredient acclaimed for its comprehensive skin benefits. Rich in protective polyphenols, it adeptly shields the skin from oxidative and UV-induced stress, actively combating photo-aging and promoting a more even, radiant complexion. It also significantly contributes to improved skin elasticity and reduced wrinkle appearance.

Science

Mechanism of Action

This extract operates as a powerful antioxidant, exhibiting an efficacy comparable to vitamin E in safeguarding the skin against environmental aggressors and UV-induced damage, thereby mitigating photo-aging and dehydration. Its rich composition of polyphenols, particularly procyanidins, provides robust antibacterial, antioxidant, and anti-aging capabilities. The ingredient effectively reduces malondialdehyde (MDA) levels in human fibroblasts exposed to UV-A radiation, directly indicating its capacity to counteract oxidative damage. Key active compounds, including rutin, ferulic acid, and epicatechin, further enhance its protective profile by suppressing inflammatory factor expressions (e.g., IL-1β, TNF-α, COX-2), thereby calming the skin, reducing redness, and assisting in the restoration of physiological pH.

Dusting Analysis

Not commonly dusted

Clinical efficacy observed at concentrations as low as 0.05% suggests that Litchi Chinensis Pericarp Extract is an active ingredient, not typically used solely for 'dusting' purposes.

Stability

Optimal extraction of active phenolic compounds and the highest antioxidant activity of its anthocyanins are achieved within a narrow pH range of 3.0 to 4.0. The inherent instability of the extract outside this range can limit its application and necessitate precise pH control during formulation.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Clinical investigations at 0.05% and 0.1% concentrations reported the litchi serums as stable and non-irritating. While formal safety assessments from CIR, SCCS, or FDA are not yet available, cosmetic products containing this ingredient are subject to rigorous safety evaluations under EU regulations.
