The Benefits of Vitamin C



Written by Skin Therapist Joanne Rendell


What Does Vitamin C Do?

Vitamin C is an essential vitamin, necessary for the growth, development and repair of our body’s tissue. A powerful antioxidant, it protects against free radical damage, helps the body to absorb iron, boosts the immune system and enhances wound healing and scar tissue.  

Bright and Beautiful

Although Vitamin C is great for addressing signs of ageing; it has potent skin-brightening benefits, too. So, it’s a great ingredient to look out for if you’re keen to turn dull into glowing. Vitamin C promotes healthy cell turnover, which means it can be very effective at diminishing the appearance of hyperpigmentation, and evening out red, blotchy skin and Rosacea. While Vitamin C isn’t a SPF per se, it does help to limit the damage caused by UV exposure, as it can significantly boost your SPF’s efficacy when layered underneath. 

Which one is right for me?

There are many ways to incorporate Vitamin C into your daily skincare routine. But it’s important to realise that not all Vitamin C products are created equal. Firstly, you need to choose the right concentration for your skin type, to avoid any potential irritationMedik8 C-Tetra is a perfect product for anyone that is new to Vitamin C. It is also worth knowing that sometimes, Vitamin C is in disguise if you’re checking ingredient lists, look out for common aliases such as L-ascorbic acid, ascorbic acid and L-ascorbate. 

Getting the most out of your Vitamin C

Things to consider when choosing a Vitamin C for your routine - Vitamin C is water-soluble, which can make penetration difficult, and it breaks down when exposed to oxygen. This means it loses its potency after contact with light, heat and air. So, its important to store your Vitamin C skincare products at room temperature and out of direct sunlight dark glass and opaque packaging helps, too. And do pay attention to your chosen products shelf life. Most formulations need to be used within three months of opening to ensure you are getting the best out of the product. 

How do I bring Vitamin C into my routine?

One of the easiest ways to introduce this wonder ingredient to your skincare routine is with a Vitamin C face serum. As with all serums, apply after cleansing and before moisturising. Most Vitamin C products are recommended for daytime use only and once moisturised always apply SPF.
