The Medik8 CSA Philosophy Kit Advanced Edition contains: 

Medik8 Surface Radiance Cleanse

Start your daily anti-ageing routine with this multi-tasking cleanser enriched with Mandelic, Lactic and Salicylic acids that refines, renews and purifies skin to remove dead skin cells and reveal a radiant and smooth complexion. 

Medik8 Surface Radiance Cleanse removes all dirt, oil and unwanted bacteria thoroughly from the skin, leaving luminous and clarified skin.

Medik8 C-Tetra+ Intense

Medik8's C-Tetra+ Intense is an extremely stable Vitamin C serum, which helps combat sun damage to the skin while triggering collagen synthesis and increasing the skin's elasticity and density.

It also improves the skin's texture and brightens the complexion. This formula is designed for those seeking a higher strength Vitamin C serum. 

Medik8 Advanced Day Total Protect

This rich and nourishing yet lightweight formula is designed to protect skin against UV damage and sun-induced skin ageing. The broad-spectrum sunscreen protects against free radical damage, while an effective blend of humectants known as Moisture Magnets ™ offer superior hydration.

Medik8 Crystal Retinal 6 

This groundbreaking cream-serum is formulated with 0.06% Retinaldehyde, a super-charged derivative of vitamin A, which works to promote the skins natural collagen production, rebuild lost collagen and increase cell turnover, promoting a smoother, brighter and healthier complexion.

By requiring only one conversion to retinoic acid, the Crystal Retinal™ works 11 x faster than other forms of retinol, delivering results comparable to clinical-grade vitamin A. Trials have shown that in as little as four weeks, users have seen a vast improvement in the appearance of pigmentation, fine lines, wrinkles and breakouts and have an overall improved complexion. With the innovative crystal encapsulation system, the Retinaldehyde is slowly time-released, helping to reduce irritation, making this suitable for all skin types, including those who have previously been sensitive to Retinol. 

With other key ingredients including Hyaluronic Acid and Vitamin E, the skin is hydrated at every level, leading to a plumper and smoother complexion and the skin barrier is strengthened, helping to lock in moisture. With a lightweight, silk-like texture that absorbs quickly into the skin, this powerful serum renews and resurfaces the skin, visibly minimises fine lines and wrinkles, reduces blemishes and pigmentation and delivers a healthier, brighter and more even-toned complexion.
