How do I use Vitamin C in my skin care routine

5 Mins Read

Vitamin C will very likely work wonders for your skin – it's anti-aging, helps treat hyperpigmentation and can brighten a dull complexion overnight. If you’ve got old ‘acne’ scars or redness, the right Vitamin C can probably help fade them, if you’ve been sun damaged and it left a pigmented imprint (your forehead, your cheeks, your hands) a bit of Vitamin C on rotation with some Retinol can deliver a difference that’s quite radical  –  in fact, there’s a perfect Vitamin C product for almost every skin type and complexion concern.

Now chances are, you already know what Vitamin C is and maybe even how Ascorbic Acid works on your skin. You might already be using what-according to dermatologists-  are the most effective Vitamin C formulations. But for most laypeople - those who don’t want to deep dive into the difference between L-Ascorbic Acid,  Sodium Ascorbyl Phosphate and Magnesium Ascorbyl Phosphate (we’ll stop there, because we could go on for hours), the really important question is: How do I use Vitamin C in my skincare routine? And what is the best Vitamin C serum for my skin type?

And at BEAUTY PIE, we work with the world’s best skincare chemists to ensure every mix of actives in our products really delivers, but we also love an expert dermatologist. We asked Consultant Dermatologist Dr. Andrew C Markey MD FRCP to give us his advice on how to make Vitamin C work its magic fastest.

How to use Vitamin C for Skin - Your Expert Guide

How often should I apply Vitamin C for optimum results?

Daily.

Dr. Markey says “Dermatologists often recommend Vitamin C as part of a morning routine because, unlike retinoids, it isn’t impacted by ultraviolet light and even helps to prevent UV damage during the day.

New data also suggests that using antioxidants, like Vitamin C, in the evening may help fight post-sun skin damage too.”

When do I use Vitamin C in my routine?

Vitamin C absorbs into skin most effectively after cleansing.

  • AM: after cleansing, allow to absorb before applying a moisture lotion/SPF.

  • PM: add a dose to your go-to night moisturizer, or layer a Vitamin C serum beneath it for a boost.

How do I use Vitamin C in my skincare routine?

“The benefits of using a Vit C serum can be extensive. Ascorbic Acid in high concentrations (15%+) will treat more persistent skin problems, but lower concentrations are also effective.  On rosacea and sensitive/dry skin where you’d want to avoid L-Ascorbic Acid you can use the gentler Vitamin C esters,“ says Dr. Markey. Research shows that even concentrations of 0.6% have antioxidant and reparative properties. Here’s how-to find the right one for you:

1. Identify your need

The best Vitamin C serum for anti-aging

“Vitamin C’s real strength is in anti-aging,“ says Dr Markey. “Pure Ascorbic Acid has consistently been proven to be the most effective form of Vitamin C but it needs to be made fairly acidic to penetrate the skin barrier, which can irritate some skin types.“ Its effectiveness increases further when combined with other antioxidants, such as Vitamin E and Ferulic Acid providing increased protection against free-radical damage.

The best Vitamin C serum for acne scars and acne-prone skin

“Vitamin C has anti-inflammatory effects so can also help with acne – and high concentrations of gold standard pure Vitamin C (15%) and Ferulic Acid (.5%) work to help reduce pigmentation marks (post inflammatory pigmentation) and post-breakout redness as well as calming skin.” says Dr Markey. Opt for a non-comedogenic serum to help soothe acne-induced inflammation.

The best Vitamin C serum for rosacea

Look for an anti-inflammatory Vitamin C serum that's specifically made for people with rosacea, this will likely contain an ester of Vitamin C such as Ascorbyl Glucoside. A fragrance-free, moisturizing topical serum designed to help soothe irritation and redness is your best bet.

The best Vitamin C serum for dark spots, hyperpigmentation and melasma

“As it is with anti-aging, Vitamin C is a ‘magic bullet’ when tackling pigmentation and dull skin. Consider it your morning skincare essential, applied before SPF,” says Dr. Markey. “With continued use Vit C can even prevent pigmentation from forming. Look for a formula that combines Vitamin C with fellow antioxidant Vitamin E to repair as well as brighten.”

“If you have melasma (a result of hormones, UV exposure and genetics) DO remember that even if pigmentation fades, without a broad spectrum SPF50 sunscreen it may return on reexposure to the sun.”

The best Vitamin C serum for brightening dull skin

Looking for a Vitamin C overall skin- brightening serum? Opt for a product with Vitamin C and Ferulic Acid – these two ‘super’ actives will brighten dull and uneven skin brilliantly.

The best Vitamin C serum for sensitive skin

Vitamin C shouldn’t cause skin irritation if used correctly but high concentrations of Ascorbic Acid can cause sensitivity. Vitamin C esters are less active and so less likely to cause irritation – aim for a maximum 10% concentration of Vitamin C and introduce the product gradually – if it’s recommended to use it twice a day, start off with one dose. If you suspect you need to replace Vitamin C with something more gentle, Niacinamide is a great alternative. Azelaic Acid and Bakuchiol are both anti-aging and suitable for sensitive skin while Tranexamic Acid/Arbutin or Liquorice will help with hyperpigmentation.

2. Check your routine

Is it safe to use Vitamin C under eyes?

Yes. Vitamin C can help reduce the appearance of dark circles, as can certain peptides and gentle retinols.

Can I use Vitamin C serum after derma-rolling?

“Yes - unlike retinoids, Vitamin C can be used just before and just after dermarolling to increase absorption, particularly if hyperpigmentation is an issue and you’re well versed in your Vit C usage!“ If you have very sensitive skin, check with your dermatologist first or opt for a soothing serum instead. After dermarolling, we’d suggest always having a tube of Super Healthy Skin Lotion on hand.

Is Vitamin C safe to use in pregnancy?

Yes! Many dermatologists also recommend using a daily Vitamin C serum during your pregnancy to help brighten dark spots and help prevent pigmentation (aka melasma or ‘pregnancy mask’).

Vitamin C: How long until I see results?

You’ll start to see significant changes in your skin after six to eight weeks.
