- Water-free, 100% stable formula – ensures long-lasting potency from the first drop to the last

How It Works
Your skin naturally contains antioxidants that protect against environmental free radicals. However, when free radicals overwhelm your skin’s defences, they cause damage that accelerates premature ageing.
Medik8 C-Tetra and C-Tetra Luxe serums are formulated with Tetrahexyldecyl Ascorbate, a powerful and stable form of vitamin C. This supercharged antioxidant not only neutralises free radicals but also stimulates collagen synthesis to reduce fine lines and promote a firmer, more youthful look.
Together with vitamin E, these serums form a “network antioxidant” system, offering enhanced protection and a healthy, glowing complexion throughout the day.
Why Choose Medik8 C-Tetra Serums?
- Advanced formulas for daily radiance and long-term skin health
- Perfect for all skin types, including sensitive skin
- Non-irritating, lightweight, and easy to layer under moisturiser or sunscreen
- Scientifically backed, dermatologist-recommended
Restore your skin’s youthful glow and shield against environmental stress with Medik8 C-Tetra and C-Tetra Luxe – the ultimate vitamin C serums for healthy, radiant skin.

Our Midnight Antioxidant Complex, consisting of a cell repairing peptide, dragon fruit extract, and saskatoon berry, caters to your skin’s need for overnight repair after exposure to environmental free radicals. The result? A visibly healthy, youthful glow by morning.
To further enhance its effectiveness, N-acetyl glucosamine works in synergy with retinol to boost the production of hyaluronic acid, helping to firm, plump, and encourage a youthful-looking complexion.

Medik8 Pore Refining Scrub (75ml)
Medik8 have discontinued Pore Refining Scrub
I recommend;
Image Ageless Total Resurfacing Masque
Image Vital C Hydrating Enzyme Mask
Skinceuticals Clarifying Clay Masque | Deep pore cleansing skin-refining masque
This creamy facial scrub uses the powerful complex of chemical and physical exfoliants.
Salicylic and mandelic acid dissolve impurities & oil to decongest and tighten pores, whilst natural jojoba grains gently exfoliate away dead skin cells.
Pores are left virtually undetectable and skin feels soft, smooth and supple.
DIANE'S TIP: Use 2/3 times a week after cleansing
Massage into damp skin for 5 mins - can be left on skin for a further 5-10 mins where you have lots of blackheads, blocked pores, bumps under the skin or ingrown hairs
Don't exfoliate everyday as this strips away the healthy oils.
