Continue your journey to a youthful future with The CSA Kit Retinal Edition. It is the perfect stepup for those looking to upgrade their anti-ageing results with next-generation vitamin A technology.
Featuring Surface Radiance Cleanse™, C-Tetra, Advanced Day Total Protect, Crystal Retinal 3.

Surface Radiance Cleanse - Infused with an exfoliating blend of mandelic, lactic and salicylic acid. This uplifting citrus cleanser gently renews and purifies to uncover a visibly smooth, radiant complexion.

C-Tetra - Restore radiance and fight visible signs of ageing. Utilising the antioxidant power of tetrahexyldecyl ascorbate (stabilised vitamin C) and vitamin E, the hydrating serum visibly brightens and smooths the complexion, while fighting free radicals to reduce visible signs of ageing.

Crystal Retinal 3 - Formulated with stabilised retinal, a powerful derivative of vitamin A with next-generation anti-ageing results. Unmatched in its age-defying power, Crystal Retinal 3 works to visibly minimise fine lines and wrinkles; firming, resurfacing, decongesting and softening the appearance of skin.

Advanced Day Total Protect - A lightweight day cream that boasts a range of protective technologies and helps to replenish skin’s hydration levels to promote a supple and youthful appearance. With sunscreen protection, this daily moisturiser is lightweight and perfect for wear under makeup.

Exfoliating Acids (Surface Radiance Cleanse)
AHAs l-mandelic acid and l-lactic acid softly exfoliate the skin, while deeply hydrating for a nourished complexion. Mandelic acid, in particular, is able to work on both the surface of the skin and within pores for a thorough yet gentle cleanse. BHA salicylic acid can decongest and exfoliate from within the pore, helping to minimise the appearance of enlarged pores and blemishes.

Tetrahexyldecyl Ascorbate (C-Tetra)
A lipid-soluble form of vitamin C that provides exceptional antioxidant protection from harmful free radicals, for a youthful-looking complexion.

0.03% Retinaldehyde (Crystal Retinal)
Proven to work up to 11 times faster than retinol, retinaldehyde is a revolutionary form of vitamin A that targets the appearance of fine lines and wrinkles, hyperpigmentation and uneven skin texture.

Superior UV Filters (Advanced Day Total Protect)
A complex of sun filters carefully selected for their longevity, gentleness and power to protect the skin against harmful UVA and UVB rays.

Start your anti-ageing skincare ritual by cleansing with Surface Radiance Cleanse both morning and night. Massage into moistened face and neck. For sensitive or dry skin, use once a day or whenever a deeper cleanse is required. Gently remove by splashing with water and pat face dry.

2 C-Tetra

After cleansing in the morning, massage 6 drops of C-Tetra across the face, neck and décolletage. Leave to absorb before applying moisturiser.

3 Advanced Day Total Protect

Follow with Advanced Day Total Protect. Apply a liberal amount to face, neck and décolletage. Use light, upward strokes and allow to absorb. Reapply throughout the day as needed.

4 Crystal Retinal 3

Use in the evening. First cleanse, then apply Crystal Retinal 3 over face and neck. Allow to absorb then follow with a moisturiser. Gently squeeze the tube as you activate the pump to ensure every drop is dispensed.

Crystal Retinal 3 application should be phased in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night.
