As a core part of the Medik8 regimen, vitamin C is a must-have in any morning skincare routine. We are happy to tell you why this vitamin is so important.

There are many different forms of vitamin C. However, they all work towards the same end goal: radiant, youthful and protected skin. Vitamin C works with your skin cells to stimulate collagen production and also helps block the enzyme that causes pigmentation. Considered one of the best antioxidants in skin care, vitamin C is able to fight free radicals that can cause premature aging. Free radicals are highly reactive molecules with an unpaired electron. Since they don't have an electron, they try to complete their pair by stealing an electron from other molecules.

Our body has a natural defense system of antioxidants, which give the free radicals a spare electron to prevent them from damaging our skin cells. When there are more free radicals than antioxidants, the skin becomes overwhelmed in a process called oxidative stress. Then it can no longer fully protect itself against free radical damage. The radicals can attack collagen molecules, cellular DNA and cell membranes to weaken them. This impairs cellular regeneration leading to sagging and wrinkled skin.

Boost your antioxidant system

Vitamin C provides a boost to the body's natural antioxidant system to help it fight free radicals; protect the skin from their harmful effects. Antioxidants are exceptionally important in our morning routine to provide all-day protection from the environment, so include Vitamin C or Firewall®.

While vitamin C (L-ascorbic acid) is exceptional at targeting signs of aging, there is a bit of a challenge. Pure L-ascorbic acid is unstable in water-based formulations. In water it is oxidized and causes a cascade of reactions in which it loses its potency and can even become a pro-oxidant – meaning it can form free radicals itself. When vitamin C becomes unstable, products can often turn yellow, which is a sign that you should stop using the product. Medik8 believes you have to make a compromise – the perfect vitamin C serum is stable, feels great on the skin and provides exceptional skin antioxidant protection. We have therefore formulated serums with 3 different forms of vitamin C:

*L-ascorbic acid

This is the vitamin C for purists looking for results. We have taken exceptional measures to ensure that our Pure C15™, which contains 15% ascorbic acid, is highly stable before opening and has a minimum shelf life of 8 weeks once opened. Supplied in two separate bottles, you get 2 x 8 weeks supply making it excellent value for money.

We have optimized the pH of our formula to ensure that the ascorbic acid has the most effect, but with minimal irritation. We produce the formula in a room saturated with nitrogen, instead of air, to prevent ascorbic acid from coming into contact with oxygen and becoming unstable. Ascorbic acid is combined with vitamin E and glutathione, two other antioxidants found naturally in the body.

This antioxidant complex mimics the skin's natural defense system and forms a rechargeable network of antioxidants. The antioxidants work synergistically to boost their overall antioxidant power while regenerating each other for long-lasting potency. This means the vitamin C is on uninterrupted to stimulate collagen production and help inhibit the formation of hyperpigmentation, for brighter, younger-looking skin.

*Trahexyldecyl Ascorbate

An oil-soluble derivative of L-ascorbic acid, tetrahexyldecyl ascorbate. Tetrahexyldecyl ascorbate has a long name and a long shelf life. Super stable and ideal for penetrating deep into the skin's lipid barrier. This provides this derivative with easy access to the vitamin C range, with very little irritation. Included in our C-Tetra® range along with beneficial soothing oils. Tetrahexyldecyl ascorbate is perfect for tackling lines and wrinkles while nourishing and caring for the skin.

*Ethylated L-ascorbic acid

And last but not least: our most powerful form of vitamin C introduced in Super C30™ (Now with Ferulic Acid). The molecule is based on ascorbic acid, but has a carbon chain attached to the most reactive part of the molecule, preventing it from being oxidized. This means that ethylated ascorbic acid retains all the efficacy of PU L-ascorbic acid without any stability issues. Expect a slight tingling sensation when you apply this due to its potency, which will disappear within a few minutes. We use only chirally correct Vitamin C in all our products to ensure it reaches its full potential on the skin.
