Cosmedix Define Age-Defying Treatment


Size: 45g

Every great skincare journey starts with a vitamin A and AHA exfoliating acids to resurface, hydrate and restore skin health. This gentle, multi tasking retinol complex reduces excess oils in skin prone to breakouts and targets premature ageing all at the same time!

A perfect choice for anyone wanting to introduce a Vitamin A to their evening skincare ritual, infused with skin-soothing botanicals to help improve your complexion without sacrificing hydration or inflaming your skin. Its micro-encapsulated technology ensures the vitamin A causes minimal irritation while maximising its absorption into the skin where it’s most effective.

How do I use this in my skincare ritual?


Apply a pea size amount to your freshly cleansed face and neck (excluding your eyes and lips). It may initially have a very mild tingling sensation on the skin which will subside within seconds and disappear altogether once your skin has become accustomed to it. Start usage every 3rd night, working up to nightly use. Use as tolerated in conjunction with your evening skin ritual. *We do not recommend this product to be used in your daytime ritual, as it may cause sensitivity to sun exposed skin. Protect your results with Extreme B17 Serum and one of our skin loving sunscreens during the daytime.


Want to give your skin an extra kick? Clear Skin Boosting Pads are perfect for skins needing an added exfoliating and deep cleansing treatment 1-2 times weekly (do not use these on the same evening you are using your Define).
