A1 Vitamin A Power 1 offers an intelligent new approach to retinoids, supported by our exclusive TTS³ Technology.
This medium-strength serum has been specially developed for skin already accustomed to retinoids, harnessing the incredible benefits of retinol and retinal, while unleashing a powerful synergy between vitamin A and the EGF peptide growth factor. Through enhanced retinoid activity that 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 becomes smoother.
A1 is lightweight and absorbs quickly. It integrates seamlessly into any nightly routine and can be combined with other products.
2 forms of vitamin A, retinol and retinal, stimulate cell renewal and promote the production of collagen and elastin, resulting in plumper, smoother skin and a reduction in fine lines and wrinkles.
EGF peptide growth factor enhances vitamin A activity through synergistic effects while supporting the skin’s natural repair process.

How to use
Evening application: After cleansing, apply 1–2 pumps, avoiding the eye area. Then apply your eye cream and night-time moisturiser. Always wear sunscreen during the day while using this serum.
First-time use of vitamin A:
If you are using retinoids for the first time, we recommend a slow, gradual transition to A1. To build tolerance gradually, apply the serum twice weekly at first and monitor skin reactions before increasing use. If irritation or discomfort occurs, reduce the frequency of application.
Regular vitamin A users:
If your skin is already accustomed to the effects of retinoids, you should use A1 every night to achieve optimal results. To minimise the risk of skin sensitisation, do not use multiple retinoids at the same time.
