Vitamin C for brighter glowing skin

When it comes to vitamin C, more often than not we tend to associate it with boosting our immune system and helping fend off colds and flu but if you didn’t know already, it also works wonders for our skin. Loved by pretty much every skincare expert, it’s renowned for its brightening and anti-ageing benefits as well as being one of the strongest protective antioxidants out there. Along with vitamin A (retinol) and ceramides, vitamin C is a key player in your skincare line-up.

A natural component of healthy skin, this water-soluble vitamin, is abundant in our skin when we’re young but as we age, our levels naturally deplete and unprotected sun exposure (UV damage) and pollution can further accelerate this decline, leading to uneven skin tone, rough texture, fine lines and general dullness. However, the good news is that this skin saving ingredient is incredibly easy to integrate into your skincare regime and will help fight free radical damage caused by the environment, boost collagen (making skin look firmer) fade pigmentation, repair tired, lacklustre skin and will put the glow back in your complexion. And in these unsettling circumstances we’re presently in, we could all do with a little brightening up!

For me, a vitamin C serum (serums are made of smaller molecules, so the skin absorbs them quickly and deeply) is a great place to start. Research also shows that high strengths of vitamin C (10 per cent and higher – typically found in targeted treatments or serums) are particularly effective.

When choosing the right one for you, it can be confusing as it comes in lots of different forms, but ascorbic acid is the one to look for (also known as L-ascorbic acid). This is the most stable and effective form of vitamin C in skincare, so if in doubt, that’s the one to look for. Also because of its ability to protect your skin from UV damage and environmental aggressors, vitamin C is best used as part of your morning skincare routine; that being said, you can use it at night too (especially higher percentages of vitamin C ). If you’re new to using vitamin C, you may experience a slight tingling on first using, if this is the case, start slowly, perhaps three times a week and gradually build up to daily use. 

It’s also worth noting that vitamin C can be a tricky ingredient; keep in mind that it is extremely sensitive to air and light and will break down over time if routinely exposed to them. If you want to get the best possible results from your vitamin C serum it needs to be in an opaque, air-tight container to help ensure the ingredients remain stable; this is why you’ll often see vitamin C serums in dark bottles.
