Pregnenolone is also thought to have antioxidant properties, which can help protect the skin from environmental damage and premature aging.

3. Usage Pregnenolone:

Pregnenolone is typically found in skincare products such as serums, creams, and lotions. It can be applied topically to the skin, either as a standalone ingredient or in combination with other anti-aging compounds.
