We all know vitamin C is beneficial for our bods and immune systems, but it also has a positive effect on our skin.

When it comes to complexions, it helps defend against pollution and cellular- oxidisation. The damage to cells by free radicals — triggered by the UV radiation in sunlight and pollution, among other things — causes signs of ageing, like lines and dehydrated skin.

As the body is unable to produce vitamin C itself, it relies on products, as well as food and drink, to keep quantities up.

Here’s our round-up of the best vit-c packed products to load up on for skin protection…

Vitamin C Paste, £32, LIXIRSKIN

A natty little product to work into your mindful morning routine; maybe let it do its work while you make your lemon water. With vit c in acid form, 10% L Ascorbic Acid, it brightens and tightens the skin by removing dead skin, targeting free radicals and boosting collagen. And bonus, it a provides a natural sunscreen against UVA and UVB rays.

Truth Serum, £42, Ole Henriksen

This hero product is a vit-packed must. The mini size (which is more ‘affordable’) is a ideal for holiday packing if you’re jetting off for some winter sun.

Though it has almost no scent, this serum packs a brightening punch and evens skin tone.

Vitamin C with Grape Seed Serum, £39, Alpha-H

A neat little bottle for Santa to pop in your stocking this Christmas, to boost skin protection with noticeable results.

Stabilised Vitamin C Serum, £45, The Organic Pharmacy

Part of The Organic Pharmacy’s specialised serum range, this neat little 15% Vitamin C formula brightens and evens skin tone, while combating signs of anti-ageing.
