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

How C-Tetra Vitamin C Radiance Cream works on your skin
Your skin needs antioxidants to defend it against free radical damage from the environment. When environmental free radicals outweigh the antioxidants present in your skin from diet and nutrtion the skin can no longer protect itself. Free radicals create irreparable damage to our cells which leads to visible premature ageing of the skin - discolouration, sagging, wrinkles & malignant cell changes
C-Tetra Cream contains tetrahexyldecyl ascorbate, a stable form of vitamin C that boosts the antioxidant defence levels in the skin. Vitamin C stimulates collagen production to reduce the appearance of fine lines and wrinkles, leaving the complexion plump, radiant and youthful. As a lipid-soluble form of vitamin C, it is able to penetrate the skin’s defensive lipid barrier with ease, delivering benefits deep within the skin.
Vitamin C and vitamin E work together synergistically as 'network antioxidants', boosting the cream’s overall antioxidant effect.
C-Tetra Cream also harnesses superior hydration power by combining hyaluronic acid and glycerin with Medik8’s signature Moisture Magnets™. These draw water from the atmosphere and from lower layers of the skin to leave the complexion supple and moisturised.
Ingredients
Tetrahexyldecyl Ascorbate
A lipid-soluble form of vitamin C that provides exceptional antioxidant protection from harmful free radicals, while stimulating collagen production for a youthful looking.
Vitamin E
A lipid-soluble antioxidant that is naturally present in the skin. Vitamin E protects the skin from free radicals is regenerated by vitamin C for optimum power.
Hyaluronic Acid
With a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture from the surrounding atmosphere into the skin, leaving the complexion both nourished and supple.
Moisture Magnets
Medik8’s signature hydrators bind to skin cells and grab onto water to lock moisture in tight where it is needed the most.

Medik8 Press & Glow – Active Exfoliating Tonic for a Smooth, Radiant Complexion
Medik8 Press & Glow is an active, exfoliating toner that gives you a smooth, fresh, glowing complexion without flaking or irritation. Designed to deliver visible radiance while remaining gentle on the skin, this skincare tonic uses next-generation polyhydroxy acid (PHA) technology to offer effective exfoliation with minimal risk of sensitivity.
Why Choose Press & Glow?
The core exfoliating ingredient is gluconolactone (PHA 5.5%), a gentle but effective skin exfoliating acid—offering the benefits of surface cell renewal without the irritation commonly associated with more aggressive acids such as glycolic or salicylic.
Proven to be super hydrating—addressing flaky, sensitised skin that can occur after traditional exfoliating acids.
Press & Glow enables better penetration of active ingredients like vitamin C and A by gently exfoliating the surface of your skin.
With improved skin texture and enhanced radiance, make-up sits beautifully on the smoother skin surface.
Suitable for everyday use, twice a day—even for sensitive skins. No more worrying about daily irritation from your exfoliation tonic.
Key Benefits at a Glance
Gentle daily exfoliation: Uses PHA, not AHA/BHA (no glycolic or salicylic acid) – ideal for those looking for advanced exfoliation without irritation.
Smooths skin texture & brightens skin-tone: Clinically proven to improve skin glow by approximately 20 % in four weeks and deliver smoother, more even skin surface.
Hydration and barrier support: The PHA Gluconolactone also acts as a humectant, drawing in moisture rather than stripping the skin.
Enhances performance of other actives: Use in tandem with vitamin A or vitamin C serums for improved efficacy.
Ideal for sensitive skin: Clinically shown to be gentle, even on sensitive skin types—96 % of sensitive skin users agreed it was gentle with no stinging.
While this formula is designed for twice-daily use, if you are new to exfoliation consider starting once a day and building up as tolerated.

All skin types — including normal, dry, oily and combination.
Those with sensitive, easily irritated skin who still want the benefits of exfoliation.
Anyone looking to smooth skin texture, boost radiance and prepare skin for better absorption of active treatments.
