An anti-oxidant. Is also called 6-paradol. It might be able to neutralize free radicals in skin. The manufacturer claims that it is able to stimulate synthesis of hyaluronic acid in skin, but there is no evidence of effectiveness of this ingredient so far. The only evidence of efficacy for this ingredient so far come from small lab tests. This ingredient comes together with Caprylic/Capric Triglyceride as part of the complex called SymDecanox HA produced by a cosmetic ingredient supplier Symrise.
