With the promise of brighter skin, additional environmental protection and anti-ageing properties, it’s no surprise Vitamin C is a popular part of many people’s skincare regimen.

Yes, the same vitamin advertised on orange juice bottles can really do wonders for your skin. While a balanced diet packed will undeniably contribute to a healthy complexion, only a fraction of vitamins ingested actually go to the skin, so sometimes it needs a little extra help (to be clear: we’re not advising you wash your face with OJ). That’s where serums come in!

By applying vitamin C topically, you can target areas of concern more effectively. Luckily, myriad beauty brands have bottled its power, with countless Vitamin C serums on the market that promise brighter, glowier skin .

But with so many to choose from it can be hard to know which will be the most effective. The Cosmopolitan Australia team have put a range to the test to round up our favourite options.

What Does Vitamin C Do For Your Skin?

The topical application of Vitamin C has many benefits for the skin, with its most significant being its skin-brightening effects. The vitamin helps even the skin’s tone and texture, and reduces the appearance of dark spots and hyperpigmentation. It also combats signs of ageing such as fine lines and wrinkles. 

Can I Use Vitamin C On My Face Every Day?

Many people can use Vitamin C daily. However, given it is an active ingredient, those with sensitive skin may want to be more conservative with usage. If you struggle with rosacea or sensitivity, perhaps start applying every other day and work their way up.

Vitamin C should be applied as part of your morning routine, after cleansing and before SPF and moisturiser.
