Oleoyl Serotonin is primarily used in the field of dermatology and skincare due to its ability to modulate serotonin receptors and influence lipid metabolism in the skin. It is commonly incorporated into cosmetic formulations to enhance skin barrier function, improve hydration, and reduce inflammation. The compound helps in maintaining skin elasticity and firmness by promoting the synthesis of essential lipids, making it effective in anti-aging products. Additionally, it has shown potential in alleviating symptoms of skin conditions like eczema and psoriasis by regulating immune responses and reducing irritation. Its soothing properties make it a valuable ingredient in products designed for sensitive or damaged skin.
