What it is: High-level vitamin A & peptide moisturiser
- Part of the Skin EssentiA® range, this advanced moisturiser is formulated with a high concentration of vitamin A (Retinyl Acetate) and Matrixyl® 3000 peptides to assist in wrinkle smoothing and improving skin tone and elasticity.
- It helps significantly repair the visible signs of photo-ageing and environmental damage while shielding the skin with a "full brigade" of antioxidants. It is the fourth step in the Vitamin Step-Up System™, designed for skin that has already been acclimatised to high levels of vitamins.
Best for: Advanced Environ users who have successfully completed at least 2 bottles of AVST 3, and those with mature or photo-damaged skin.
What it does: Normalises, firms, protects, and targets deep lines and wrinkles.
