Vitamin D3

Vitamin D3 is the naturally occurring form of vitamin D used in skincare for its antioxidant and skin-conditioning properties. It helps support the skin's natural barrier, contributes to healthy skin function, and may help reduce the appearance of irritation caused by environmental stress. It is typically included in moisturisers, barrier repair creams, and products formulated for dry or sensitive skin. Although research into its topical benefits is ongoing, it is primarily used to support overall skin health rather than as a primary active ingredient.
