Environ Vita-Antioxidant AVST Moisturiser is part of a progressive vitamin A step-up system designed to introduce and gradually increase vitamin A in the skin without irritation. Each level builds on the last with increasing concentrations of vitamin A alongside vitamin C and a powerful antioxidant complex, allowing skin to adapt safely while delivering meaningful anti-aging and skin-normalizing results over time.

Vitamin A is one of the most effective and well-researched ingredients in skincare, but introducing it too quickly or at too high a concentration is a common cause of irritation, redness, and peeling. The AVST system solves this by allowing skin to progressively acclimatise, starting at a lower concentration and increasing in strength as tolerance builds. This approach delivers the long-term benefits of vitamin A with significantly less risk of disruption to the skin barrier.

Vitamin A plays a central role in regulating how skin cells function, helping normalize oily, congested, and uneven skin while supporting smoother, healthier-looking texture over time. As the AVST level increases, this normalizing effect becomes more pronounced, helping the skin behave the way it did at a younger age. Consistent use supports steady improvement in clarity, tone, and surface quality.

As vitamin A concentration increases through the step-up levels, its role in supporting collagen and elastin production becomes more significant, helping skin maintain firmness and elasticity over time. This is paired with vitamin C, which works alongside vitamin A to further support collagen synthesis and protect the skin from oxidative stress that breaks down these structural proteins.
