How to Use Vitamin C to Get The Skin You'll Ever Have

Curated by Claudia Shannon / Research Scientist / ishonest

When it comes to the vitamin that offers up the greatest body benefits, the one named “C” arguably takes the crown. And it’s not just your insides that are BFFs with vitamin C: this nutrient can also help transform the appearance of your skin.

“Vitamin C products are packed with antioxidants that are known for providing a brightening and “glowy” effect on our skin,” says dermatologist Dr. Kathy Taghipour. “It naturally improves the appearance of skin by fighting signs of aging and UV exposure, along with hyperpigmentation and dark patches.”

So hell yeah, add this to your beauty regimen — but before you buy the first thing you see, learn about what exactly makes vitamin C (aka L-ascorbic acid) so powerful so you can not only convince all your friends but also know which products work best for your skin.

When it comes to your skin, vitamin c has a truly noteworthy resume

1. Fights lines and wrinkles

When it comes to fine lines, wrinkles, and other signs of your skin’s wear and tear, vitamin C is a handy tool to have in your arsenal. Research shows this nutrient helps protect against damage and aids in skin regeneration, by neutralizing free radicals.

2. Revitalizes sun-damaged skin

Prolonged sun exposure does a number on the skin — flakiness, discolored patches (sunspots), rough areas, rosacea, etc. But topically applying a daily vitamin C dose may guard your skin from taking too much damage.

One study found people with mild to moderately photo-damaged skin experienced a significant improvement in skin appearance, including fine lines, roughness, and skin tone, after using a topical vitamin C treatment for 3 months.

3. Evens out tone and minimize redness

Blotchy, uneven skin can result from a number of factors, from sun exposure to hormones to medical conditions.

The good news is, vitamin C has proven itself a hearty warrior in the fight against redness, as it helps mend the damaged capillaries that cause this discoloration and strengthen them for the future.

4. Hydrates thirsty skin

With the average adult carrying 2 square metres of skin on their body, this organ is certainly thirsty — and we’re not talking about looking for attention.

Comprising 64 percent water, your skin needs to be kept hydrated, and your new chum vitamin C is here to bring the juice (or water, we should say). It also helps your skin retain water, preventing it from becoming too dry or oily.

5. Improves elasticity

Topical vitamin C has been shown to encourage collagen production, a naturally occurring protein in our body that helps give skin that tight, plump look.

Since the body naturally makes less and less collagen as it ages, using an ingredient like vitamin C can help slow down skin aging.

6. Helps reduce inflammation

If your skin is red, irritated and showing signs of a rash, there’s a good chance that an underlying immune response, infection, or allergic reaction is behind it.

While many causes require medication to ease their effects, studies show topical vitamin C to be effective in relieving signs associated with inflammatory skin conditions such as dermatitis, acne, and psoriasis.

7. Eases hyperpigmentation

Hyperpigmentation refers to dark patches of skin, caused when the body produces too much melanin (the pigment that gives your skin its color).

While generally not harmful, hyperpigmentation can prove distracting — but topically applying vitamin C has been shown to decrease its signs, as it inhibits production of tyrosinase, an enzyme that contributes to melanin production.

8. Calms down sunburn

While we’re certainly not suggesting vitamin C as an alternative to ditching the SPF, if you do have a sunburn mishap, it can help steer you away from Rudolph territory.

This clever nutrient helps speed up cell turnover, meaning sunburned skin is rejuvenated and heals faster.

9. Aids healing

As if it didn’t already boast enough superpowers, vitamin C has been proven beneficial in helping repair wounds.

This is thought to be as a result of its ability to increase the movement and number of fibroblasts in our skin — the connective tissue cells that are key to the healing process.

How to incorporate vit c into your routine

While this antioxidant is in many of our everyday foods (kale, broccoli, strawberries, and oranges, especially), you have to apply it topically for your skin to enjoy its full effects.

The good news is, whether your skin is dry, oily or some weird combo you’re still trying to figure out, vitamin C doesn’t play favorites — as long as you play nice and apply it correctly.

“Vitamin C is best implemented into your routine with a serum, as this allows the L-ascorbic acid to remain stable and more effective,” Dr. Taghipour explains. “It will also absorb into the skin better, as serum is a lighter formulation than moisturizer.”

In terms of when to use it, vitamin C should become a staple in your morning routine, as this allows it to do its work in protecting skin from free radicals during the day.

“You should cleanse and tone, then apply your vitamin C serum and follow with a moisturizer,” says Dr. Taghipour.

Don’t forget to apply sunscreen after moisturizing, in order for the two products to work well together to combat UV exposure, she adds.

Quick take: Apply a vitamin C serum once or twice a day, after toner and before your moisturizer. Always wear SPF with products that contain vitamin C.

How to shop for a vit c product

Once you start Googling you’ll realize just how many vitamin C products are out there. Keep these tips in mind.

1. Look for L-ascorbic acid

Lots of products claim to contain vitamin C, but for this antioxidant to be truly effective, you need to look for L-ascorbic acid in the ingredient list — as this is its most stable form.

2. Concentration is key

Dr. Taghipour recommends starting with a 10 percent concentration to see how it suits your skin. “You can then move to a product containing a higher concentration of 15 to 20 percent if you feel this is required and your skin can tolerate it,” she says.

Make sure the product has at least 10 percent, she adds, as any less than this won’t be effective.

3. The container shouldn’t let air or light in

Vitamin C is super-sensitive to light, so the sun’s rays will break it down faster if it’s in clear packaging. As such, you also want to keep it stashed away in a cool, dark space — such as the fridge — as heat exposure reduces its potency too.

Although vitamin C serums are often a yellowish color, if the tint turns darker or brownish, that’s a sign it’s turned and should be tossed.

4. It contains complementary ingredients

Your vitamin C product will be the most effective if it contains the following complementary ingredients:

  • Ferulic acid. It’s been proven to increase vitamin C’s stability by 90 percent.
  • Vitamin E. This antioxidant boosts UV protection.
  • Glutathione. This also has antioxidant properties.
