Skin and Scalp Health Benefits of a Specific Botanical Extract Blend: Results from a Double-Blind Placebo-Controlled Study in Urban Outdoor Workers

A 12-week double-blind, placebo-controlled study involving 66 women working outdoors in urban areas demonstrated that a daily 250 mg oral supplementation of a botanical extract blend significantly improved skin and scalp health. The blend, containing extracts from Rosmarinus officinalis, Lippia citriodora, Olea europaea leaf, and Sophora japonica, enhanced skin antioxidant status, moisturization, radiance, and reduced wrinkle depth, dark spot pigmentation, and oiliness. For the scalp, there was increased moisturization, decreased transepidermal water loss, and reduced sebum content. Additionally, 71% of participants with sensitive scalps reported reduced redness. The study concluded that the botanical blend effectively mitigates skin and scalp damage caused by environmental pollution, with no adverse reactions reported.
