Vitamin D3 (Cholecalciferol)

Vitamin D3 is a fat-soluble active ingredient widely used in cosmetic formulations for skin conditioning and barrier-support applications. Known scientifically as Cholecalciferol, Vitamin D3 helps support skin health by improving moisture balance, promoting skin comfort, and reinforcing the skin’s natural protective function.

In skincare formulations, Vitamin D3 is incorporated at very low concentrations due to its potency. It is commonly used in facial oils, serums, creams, restorative treatments, and barrier-repair formulations designed for dry or stressed skin.

As a lipid-soluble vitamin, Vitamin D3 integrates easily into oil phases, enhancing nourishing formulations while contributing to improved skin feel and conditioning benefits.

Suitable for professional formulators developing advanced skincare products.
