2.Skin-Brightening Function
This ingredient is commonly used in brightening and tone-correcting formulations. It may help reduce the appearance of uneven skin tone, dullness, and visible discoloration by supporting the regulation of melanin-related processes. It is suitable for facial serums, lotions, creams, masks, and other products designed to promote a clearer and more radiant-looking complexion.
3.Antioxidant Protection
As a vitamin C derivative, it provides antioxidant support against free radicals generated by environmental stressors such as pollution, ultraviolet exposure, and oxidative damage. Incorporating it into skincare formulas can help protect the appearance of skin from premature visible aging and support a healthier, fresher-looking complexion.
