Vitamin B12

What Does Vitamin B12 Do For Your Skin?

Vitamin B12 is often overlooked in skincare, it actually plays an important part in speeding up cell regeneration.

Bring on the science!

'Vitamin B12 works by binding to enzymes to help with chemical reactions in the body and the skin,' he says. 'When B12 is absorbed into the skin, it boosts metabolism in the skin cells and this energy speeds up cell recovery and regeneration. In turn, fatigued skin is improved.'

And according to experts, topical use of B12 delivers even better results than oral supplements.

It just passes through your body, but continued use of topical vitamin B12 leads to thicker, firmer skin.

According to skin experts, if you're going to incorporate any vitamin into your skincare arsenal, it should be vitamin C, as it's ability to protect and strengthen the skin is second to none.

'Vitamin C is one of the most important skincare ingredients,and it should be included in everyone's regime, from teens just starting out with skincare to those after strong anti-ageing benefits.

'It's one of the most potent antioxidants around, which means it not only helps shield the skin from free radical damage caused by environmental aggressors, but it increases protection against sun damage. In fact, a vitamin C-based serum with SPF50 is the foundation of all of my clients' day-time regimes.'

And even though we can easily get vitamin C from various fruits, vegetables and supplements, it's especially important that your skincare boasts a dose of the all-rounder, too.

Vitamin E is a hero ingredient in the beauty sphere, especially for those who suffer with ultra-dry and sensitive skin, but it's also one of the best antioxidants out there.

Vitamin E never fails to deliver softer, more hydrated skin. It's so intensely moisturising and this keeps the skin looking and feeling plump and smooth, but the best part is that it also contains effective antioxidants which are known for protecting against pollution and other environmental stressors.

Vitamin E works with vitamin C to neutralise these free radicals,and this prevents the tissue damage that leads to premature ageing.

Your current moisturiser or serum is doing nothing to quench your parched patches, or you're looking to pollution-proof your skincare kit.

Vitamin E acts like armour against those pesky free radicals that embed themselves in your skin and work to dull your youthful glow.
