So what does Vitamin C do for the skin and why is it used in serums?
Vitamin C is marketed as one of the best cures for acne scarring, hyperpigmentation - aka sun damage - and dull complexion.
As a serum ingredient, Vitamin C brightens skin and also acts as a natural exfoliant to brush away dead skin cells and boost collagen production, which is the key to youthful radiance!
Dr Joseph Hkeik of All Saints Skin Clinics in Sydney, says Vitamin C is so popular because of its anti-aging benefits.
“It’s a wonderful brightener...I think this is probably the reason why it’s been thrown into a lot of products,” he told Elle Australia.
What are the proven benefits of using Vitamin C on skin?
Vitamin C has been clinically proven to brighten and hydrate, reduce inflammation and hyperpigmentation, lessen the appearance of under eye circles, promote collagen production, improve elasticity and firmness and counteract the impact of sun damage.
Are there any potential side effects of using Vitamin C serum?
According to Healthline, irritation is unlikely but it’s still advisable to take a patch test before you apply serum all over the face or body.
Those with very sensitive skin should avoid products containing L-ascorbic acid.
How should Vitamin C be used and applied to skin?
Vitamin C can be infused into products in liquid, powder or crystal form.
Dermatologists advise gradually introducing Vitamin C infused serums into your beauty routine to avoid harsh reactions.
Multiple skincare tutorials suggest applying a tiny amount morning and night, increasing steadily as required or instructed.
Because Vitamin C contains active ingredients, it’s important to keep track of your products’ expiry dates.
Hint: Anything that lists ascorbic acid in its ingredients contains Vitamin C!
Dr Hkeik says the shelf life of most products is one year from opening as Vitamin C oxidises when exposed to air.

I have a lot of scarring and hyper-pigmentation on my cheeks, I'm 29 years old and have dealt with cystic acne since I was 11.
"This has really made a visible difference on my face. Get this if you're trying to clear up scarring and a few cystic pimples. I recommend a routine of African black soap, Apple cider Vinegar toner, this serum, shea butter+ tea tree oil, and benzoyl peroxide. That's my nightly routine and it's made my skin super soft, smooth, and less red. I don't get as many pimples and if I do it's one or two around my mouth. My cheeks have ice pick and box car scarring and I feel like they've been minimized with this serum.”

(I like this better than Drunk elephant C-firma, Sunday Riley CEO, and Hylamide C25 in terms of texture and finish) In the morning I layer Paula's choice 2% BHA then The Ordinary's niacinamide, then this vitamin C, then SPF and I'm done (leave a few mins between each layer.
