Sesamoside is primarily used in cosmetic and skincare formulations for its antioxidant and skin-brightening properties. It helps in reducing the appearance of dark spots and hyperpigmentation by inhibiting melanin production, leading to a more even skin tone. Due to its anti-inflammatory effects, it is also beneficial in soothing irritated or sensitive skin. In hair care products, sesamoside supports scalp health and may promote stronger, healthier hair by protecting against oxidative stress. Its natural origin makes it a preferred ingredient in clean and plant-based beauty products.
