Your definitive guide to the most effective products for brighter, more radiant skin

A vitamin C serum should feature in everyone’s skincare routine; this wonder ingredient has the ability to protect skin, improve elasticity and visibly brighten the complexion. Vitamin C boosts collagen production – in fact, it is essential to collagen synthesis – which is vital in preventing the fine lines and wrinkles associated with the loss of this structural protein.

What is the most effective vitamin C serum?

While almost any vitamin C serum will benefit your skin, in order to get the best results it’s important to find the most effective formula for you.

If you’re new to vitamin C serums, look for a low concentration of L-ascorbic acid (or other type of vitamin C) of around 10 per cent, or mix it with some moisturiser to ease yourself in before gradually building up. If you’re looking for advice for your particular skin type or needs, why not book a free in-store consultation with one of our experts.

In the meantime, here are our picks for the best vitamin C serums to give your skin the ultimate glow.
