ERGOCALCIFEROL

Description

Ergocalciferol, also known as vitamin D2, is a crucial fat-soluble vitamin essential for calcium absorption and bone health. This compound is synthesized from ergosterol, a sterol found in plants and fungi, through exposure to ultraviolet light. In skincare and haircare formulations, ergocalciferol plays a vital role in maintaining skin barrier function and promoting hair follicle health.

When applied topically, ergocalciferol can help regulate cell growth and differentiation in the epidermis, potentially improving skin texture and reducing signs of aging. It also exhibits anti-inflammatory properties, making it beneficial for conditions such as psoriasis and eczema. In haircare products, ergocalciferol may stimulate hair growth by activating hair follicle stem cells and extending the anagen phase of the hair growth cycle.

Ergocalciferol is typically used in concentrations ranging from 0.005% to 0.1% in skincare and haircare formulations. It is often combined with other vitamins and antioxidants for synergistic effects. However, it's important to note that ergocalciferol is sensitive to light and oxygen, requiring careful formulation and packaging to maintain stability and efficacy in finished products.
