Science
Mechanism of Action
This extract exerts its dermatological benefits through a high concentration of polyphenols, particularly ellagitannins like roburins, which provide robust antioxidant protection. It actively neutralizes reactive oxygen species (ROS) to prevent oxidative stress-induced damage, thereby safeguarding essential skin components such as collagen and elastase from degradation. Crucially, a specific wood extract (Robuvit) has been shown to boost ribosomal biogenesis in keratinocyte cells, leading to increased cellular energy production and accelerated synthesis of vital skin peptides.

Safety Profile
Dermal toxicity tests conducted on Robuvit (Quercus robur wood extract) indicate it is neither an irritant, corrosive, nor a sensitizer upon topical application. While no specific Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) assessment exists for its cosmetic use, Robuvit has attained self-affirmed Generally Recognized as Safe (GRAS) status for oral consumption in conventional food in the United States since 2017, with oral dosages exceeding 700mg/day considered safe. It is important to note that historical contraindications for general oak extracts, particularly bark, relate to external use on significant skin surface damage or weeping eczema; these concerns may not directly apply to wood extract formulations.
