Why do I need a vitamin c antioxidant serum?
Think of an apple, cut in half and exposed to the air.
It will quickly go brown and bad.
If you dipped it in lemon juice it wouldn't.
Lemon juice is rich in Vitamin C (Ascorbic Acid) which prevents oxidation thus stopping the apple from going bad.
Our faces are exposed to air, pollution, UV in day-light (not just sun-shine) and HEVL blue light from phone and computers and our own oxygen waste products from breathing and stress.
All of these factors conspire to turn skin "bad" and speed up our ageing process - think of it as human rust.
Antioxidant serums prevent this from happening.

Medik8 Press and Glow Tonic

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.
Suitable For
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.
Users who currently avoid acids due to dryness and flaking — Press & Glow offers a gentler alternative to glycolic or salicylic acid toners.
Active Ingredients in Press & Glow Tonic
5.5% Gluconolactone (PHA) – gently exfoliates and hydrates the skin surface.
Prickly Pear Extract – natural enzyme exfoliation for renewal of skin surface cells.
Acai Extract – helps calm the skin and protect against free-radical damage.
Aloe Vera Leaf Juice – soothes the skin and enhances moisture retention.
