Science
Mechanism of Action
This ingredient operates by delivering a spectrum of bioactive compounds, predominantly polyphenols and powerful antioxidants such as catechins, particularly EGCG. These constituents are theorized to neutralize free radicals, thereby protecting the skin from premature aging and damage induced by environmental aggressors like UV radiation. Furthermore, it is believed to offer hydration, nourishment, and a soothing effect, potentially supporting skin regeneration and alleviating concerns such as dryness, sensitivity, and blemishes through its anti-inflammatory and potential antimicrobial actions.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded in 2014 that there was 'insufficient data' to ascertain the safety of Hydrolyzed Camellia Sinensis Seed Extract for use in cosmetic products. The panel specifically requested further data regarding its manufacturing method, full characterization, human sensitization potential, and typical concentration of use in formulations. As of the review, no new data has been submitted to address these critical information gaps.
