Vitamin A

Vitamin A is vital for life and for healthy skin, but it needs to be re-introduced to the skin slowly. Retinol is used in specific intensive serums, and the AVST moisturisers use more gentle vitamin A derivatives like retinyl palmitate and retinyl propionate to build your skin's tolerance over time. 

• Environ's Vitamin A (Retinyl Esters) are: gentler forms of the vitamin that must be converted into retinoic acid by the skin. This slow-conversion process (STEP UP SYSTEM) makes them highly effective with minimal to no irritation. 
• Retinol: is a pure, highly active form of Vitamin A. It delivers powerful anti-aging and resurfacing results but can cause initial irritation if your skin isn't used to it.
