C-Change: No7's New Vitamin C Serum Packs a Potent Punch

Glow baby, glow.

What's not to love about high-performing skincare at purse-friendly prices?

Vitamin C infused skincare has seen a 40 per cent increase in online searches recently.

And while we’re all probably familiar with its nutritional worth when it comes to fending off the dreaded flu (or the slightly more retro scurvy), it’s equally considered a veritable ‘cure-all’ by dermatologists; promising brighter, tighter, and better-looking overall skin. 

Vitamin C is naturally present in the skin’s upper layers, but as we age, these levels deplete, leaving skin looking dull, uneven and less firm. 

When added to your skincare routine (morning and/or night), the powerhouse ingredient neutralises free radicals created in the skin during oxidative stress (aka. sun damage and pollution), boosts healthy collagen production, aids in the skin's ability to heal itself and reduces inflammation. Fixing damage, as well as preventing it.

So, vitamin C sounds like a simple and essential addition to your routine, right? Well, it is. But there are a few things to bear in mind, before jumping face first, into a vat of the stuff. 


The Type Used

When it comes to looking for a suitable vitamin C product, it’s important to know that there are several different types available. Ascorbic Acid, or L-ascorbic acid, is the most common when it comes to skincare, as it absorbs quickly and has the highest potency when applied topically. But it’s also the most temperamental to formulate – it’s v. sensitive to external factors. Other popular and slightly more stable forms include Magnesium Ascorbyl Phosphate and Ester C.

The Concentration 

Vitamin C products are highly active and therefore, can cause irritation when applied at an overly high-concertation. As a general guideline, any potency between 3 and 20 per cent (latter being the highest percentage available OTC) will be the most effective. Those with sensitive skin should start low and slow but studies have shown that percentages too high can proves redundant in terms of actual skin-absorption. 


The Packaging 

As mentioned above, vitamin C is rather difficult to stabilise and tends to lose efficacy should it come in contact with light, air and/or water. The PH of the carrier substance needs to have a suitable PH too. See? We told you it was fussy. So, to get the most out of your product (and your money), buy small and also look for opaque glass or plastic containers with an air-restrictive pump. 

With all of that red tape (or maybe, orange in this particular case) out of the way, here are our most loved products containing the hero anti-ageing ingredient.
