The main ingredient of this serum is retinol. Retinol is one of the powerful anti-aging compounds and one of the derivatives of vitamin A. This substance increases the metabolism and production of new skin cells, and this increases the level of collagen in the skin. For this reason, it reduces skin wrinkles. Increasing collagen will also prevent sagging and aging of your skin and increase its strength. Retinoids can make the skin more sensitive to UV rays, so be sure to use sunscreens with spf 30 or higher while using this product. It is not recommended during pregnancy and breastfeeding.
