✓ 14% Stabilised Vitamin C | ✓ Visibly Brighter Skin in 1 Hour | ✓ Clinically Shown: Fewer Dark Spots in 4 Weeks

Medik8 C-Tetra Luxe is the richer, double-strength sibling of Medik8's original C-Tetra: a velvety 14% stabilised vitamin C serum blended with squalane, maracuja oil and optimised red ginseng. Clinically shown to reduce the appearance of wrinkles and dark spots in 4 weeks, it is the nourishing vitamin C serum for dry skin and the first signs of ageing.

Medik8 C-Tetra Luxe carries twice the tetrahexyldecyl ascorbate of the original C-Tetra, a low-irritation vitamin C that gives exceptional antioxidant protection while supporting collagen for a visibly even, more youthful-looking complexion. Around it sits a nourishing base: squalane, an almost skin-identical lipid that supports the natural barrier; maracuja oil, rich in nutrients and fatty acids for deep nourishment and extra antioxidant protection; optimised red ginseng, which boosts the serum's brightening power; and vitamin E. In Medik8's independent four-week clinical study on 36 participants, skin looked visibly brighter within 1 hour, 94% noticed smoother, softer skin after a single use, 81% agreed visible dark spots had reduced in 4 weeks and 86% said it was the best vitamin C serum they had ever used.

Anyone stepping up from C-Tetra

Choose Medik8 C-Tetra Luxe if your skin is dry or you want more than C-Tetra's 7% in a nourishing oil; if you prefer a weightless gel and the highest C-Tetra strength, C-Tetra Advanced is the alternative.

With over 20 years in specialist skincare and medical aesthetics, Becci - an aesthetic nurse - sees a lot of dry, dull skin that has given up on vitamin C because every serum felt stripping. Clients trust her to recommend what suits their skin, not what is new, and Medik8 C-Tetra Luxe is her pick for dry complexions: double the original's strength in an oil that nourishes as it brightens.

FAQS

Is Medik8 C-Tetra Luxe the best vitamin C serum for dry skin? +

It is the one Medik8 built for dry skin: 14% stabilised vitamin C in a rich oil of squalane, maracuja and jojoba. In the brand's independent four-week clinical study, 94% noticed smoother, softer skin after one use and 81% saw fewer visible dark spots in 4 weeks. Every skin is different, but for dry, dull complexions it is the C-Tetra Becci recommends most.

What is the difference between C-Tetra, C-Tetra Luxe and C-Tetra Advanced? +

All three use the same gentle, stabilised vitamin C (tetrahexyldecyl ascorbate); they differ in strength and texture. C-Tetra is the original: 7% in a lightweight oil, for sensitive skin and anyone new to vitamin C. C-Tetra Luxe doubles that to 14% in a rich, nourishing oil with squalane and maracuja oil, for all skin types, first signs of ageing and especially dry skin. C-Tetra Advanced is the newest and strongest of the three at 20%, in a lightweight gel-serum with phyto exosomes, for visible signs of ageing on normal, combination or oily skin. Above them sits Super C Ferulic, 30% ethylated L-ascorbic acid for advanced sun-induced ageing, and the technology also comes as C-Tetra Cream (3%) and Daily Radiance Vitamin C (7% with SPF 30) for anyone who prefers a cream.

What did the clinical study on C-Tetra Luxe show? +

In Medik8's independent four-week clinical study on 36 participants: visibly brighter, more youthful-looking skin in 1 hour; improved radiance in 7 days; 94% noticed smoother and softer skin after one use; 81% agreed visible dark spots had reduced in 4 weeks; and 86% reported it was the best vitamin C serum they had ever used.

Can I use Medik8 C-Tetra Luxe with Crystal Retinal or retinol? +

Absolutely. Medik8 recommends it as part of its CSA Philosophy: vitamin C plus sunscreen by day, vitamin A by night. C-Tetra Luxe in the morning, Crystal Retinal in the evening.

Is C-Tetra Luxe suitable for oily skin? +

Medik8 lists it for all skin types but describes the texture as a rich oil and highlights it for dry skin. If your skin is oily or combination, the original C-Tetra (lightweight oil) or C-Tetra Advanced (weightless gel-serum) will feel more comfortable.

Do I need a moisturiser on top of C-Tetra Luxe? +

Medik8's directions go from C-Tetra Luxe straight to sunscreen, because the squalane and maracuja oil base is nourishing in itself. Very dry skin can add a light moisturiser in between if it wants one.

Does C-Tetra Luxe contain fragrance? +

Medik8 states it contains no artificial fragrance. The formula does include grapefruit peel oil, which gives a light natural citrus scent; if your skin reacts to essential oils, patch test first.

How many drops should I use and how long does a bottle last? +

Medik8 recommends 6 drops each morning across the face, neck and décolletage and counts around 200 uses per 30ml bottle, so expect roughly six months from one bottle.

Can I use Medik8 C-Tetra Luxe during pregnancy or while breastfeeding? +

It contains no vitamin A, which is the ingredient most people are asked to avoid. Medik8 does not publish formal pregnancy or breastfeeding guidance: as a cosmetics company it says it cannot advise on medical conditions and asks customers to discuss the full ingredient list with their midwife or GP before use. Its only general note is that the formula contains no ingredients it would recommend avoiding in pregnancy unless your doctor advises otherwise. Please check with your midwife or GP first.
