If you're here, you already know that vitamin C is good for you. But what kind of good? Here's a list of things vitamin C can do for you.
Defends against free radicals
Vitamin C is an antioxidant, which is good news. To get sciencey about it, vitamin C can donate electrons in order to neutralize free radicals created in skin after oxidative stress. Oxidative stress = sun damage. So while vitamin C can't protect skin like an SPF can, it can minimize the damage you can't see.
Boosts collagen production
Very exciting news: Vitamin C is one of the factors in stabilizing and creating collagen molecules, meaning that it's one of the most reliable anti-aging ingredients on the market. Some research also shows that vitamin C can also increase the quality of the collagen created in the body. So while topical (and drinkable) collagen aren't necessarily doing you any good, your Amazon-sourced vitamin C serum's been pulling double duty.
Reduces brown spots
Because vitamin C can aid in skin's ability to heal itself, it should be your go-to when looking to reduce red and brown spots. Add to that its anti-inflammatory properties (of interest if you're struggling with acne or rosacea), and even-toned skin is in your very near future. You already knew you were preventing damage with it; but now you're also fixing it post facto.
