A step up from your entry-level vitamin A serum (Ultimate A), this powerful serum combines stable, controlled-release retinol and acid-free resurfacing peptide technology to amplify the skin's rejuvenating effects without adding acids. Delivering a potent dose of 0.4% encapsulated retinol, this formulation reduces the appearance of fine lines, minimises excess oil, balances uneven skin tone, and gently exfoliates to optimise skin cell turnover for clearer, smoother, and more youthful skin.
