Science

Mechanism of Action

This ingredient operates by scavenging free radicals, thereby protecting skin cells from oxidative stress and mitigating the visible signs of aging. It functions as a powerful anti-inflammatory and soothing agent, effectively calming irritations, reducing redness, and alleviating itchiness. For skin brightening, it inhibits tyrosinase, a key enzyme involved in melanin production, which helps to fade discolorations. Furthermore, Tetrahydrodiferuloylmethane supports a smooth, hydrated skin surface by helping to maintain hyaluronic acid content and can enhance collagen synthesis for a more youthful appearance.
