Exfoliating Vitamin A Resurfacing Night-Time Treatment

Cosmedix Define is a unique blend of three hydroxy acids and Retinol to smooth out skin tone. With a cream base, Cosmedix Define is a gentle formula for dry skins, sensitive skins or those new to Retinol, for resurfacing and age-defying benefits.

Restore smoothness back to dry, aging skin with Cosmedix Define. Formulated with a unique blend of three alpha hydroxy acids, this multitasking cream helps exfoliate the skin to refine texture, reduce the appearance of wrinkles and smooth imperfections. Skin-soothing botanicals help to improve the complexion without sacrificing hydration or inflaming the skin, allowing the 2% AGP Complex (Vitamin A) to penetrate multiple layers for enhanced results. Wrinkles are reduced and skin tone appears more even.

A rich yet mild exfoliating cream that resurfaces as it hydrates for smoother, softer-looking skin. This unique stimulant heightens the activity of the skin to an active yet well-tolerated level of remodelling. The key is utilising Retinol A which penetrates effectively using fruit acids in a cream base.

CosMedix Define helps reverse that damage with removing the dead, unhealthy accumulated layers on the surface, and healing the deeper cells below, stimulating new cells to come through faster. These cells will show you with a brighter, more radiant, clear skin.

CosMedix Define is also effective on oily, acne, congested skins of all ages. It contains effective, natural exfoliants and retinol, a form of Vitamin A. Combined, these will give you clearer, cleaner, younger-looking and feeling skin.

Define is mildly hydrating and suitable for most skin conditions. Define is a necessary part of Cosmedix pre-peel protocol to prepare the skin for peeling treatments.

We offer a comprehensive range of skin peel treatments to expedite your skin recovery.
