A1 Vitamin A Power 1 offers an intelligent, new approach to retinoids powered by our exclusive TTS³ technology. Specially formulated for skin already acclimatised to retinoids, this moderate-strength serum harnesses the incredible benefits of Retinol and Retinal while unlocking a powerful synergy between vitamin A and EGF Peptide Growth Factor. As a result of enhanced retinoid activity, which stimulates cell renewal and healthy collagen production, the complexion is transformed: fine lines and wrinkles are minimised, firmness is restored, pores are refined, and texture is smoother. Lightweight and readily absorbed, A1 can be seamlessly incorporated into any nighttime routine and used in tandem with other products.
