Science
Mechanism of Action
The efficacy of Quercus Suber Bark extract stems from its diverse array of bioactive molecules such as suberin, a hydroxycarboxylic acid, which directly contributes to a perceptible smoothing of the skin's surface and enhanced firmness. Its abundance of polyphenols and tannins acts as a powerful antioxidant system, effectively scavenging free radicals and protecting against oxidative damage, concurrently boosting skin elasticity. Beyond these, the extract helps form a protective barrier that supports moisture retention, exhibits anti-inflammatory properties, and contributes to an improved overall skin texture and appearance.

Safety
Safety Profile
While generally regarded as safe for topical use, there is currently insufficient data from the CIR. Uncommon potential side effects include mild skin irritation, redness, itching, or allergic reactions, thus patch testing is recommended. Data for use during pregnancy and breastfeeding is lacking, necessitating professional medical advice. More comprehensive toxicological studies are needed to substantiate specific claims under European Cosmetics Regulation.
