Vitamin D3 is necessary for new skin cell production and complements the function of vitamins A and E in the regeneration process of the epidermis. Normally vitamin D3 is produced in the upper skin layers upon exposure to sunlight. However, with our modern live styles it is difficult to produce the amount of vitamin D needed.
When applied topically in high concentrations vitamin D3 also shows beneficial effects on cellular processes. This helps to increase the cellular activity around stretch marks and to rejuvenate skin.
