Vitamin C is much more than a boost to your immune system during cold and flu season. This antioxidant, like so many others, is a powerhouse skincare ingredient that rejuvenates your skin.

 

It tackles everything from hyperpigmentation and breakouts to free radical damage and scarring. Regardless of your skin concern (or even your skin type), Vitamin C is a safe ingredient that’s proven to improve your complexion and help stave away the visible signs of aging.

 

Though you can get Vitamin C through many of the foods you eat, using a topical Vitamin C serum is one of the most effective approaches to maximize all of its benefits.

 

 

VITAMIN C SERUM 101

So, what is a Vitamin C serum?

 

Put simply, it’s a serum wherein Vitamin C is the active ingredient. Kind of self-explanatory, no?

 

These serums usually combine Vitamin C with other skin-beneficial ingredients to fight free radicals, calm inflammation, soothe irritation, boost the production of collagen, brighten and even skin tone, and protect against harmful UV rays.

 

We’ll get into all of the benefits of the best Vitamin C serums a little later but, for now, let’s talk abou the five most common forms of Vitamin C found in cosmetic products: L-Ascorbic acid, Magnesium Ascorbyl Phosphate, Sodium Ascorbyl Phosphate, Calcium Ascorbate, and Ascorbyl Palmitate.

 

 

L-ASCORBIC ACID

This derivative of Vitamin C is the most common form you’ll find in skincare products and it also has the most research behind it. L-ascorbic acid is prized for its ability to protect against UV rays, increase collagen and elastin levels, improve skin tone and texture, and reduce dark spots and discoloration.

 

On the downside, L-Ascorbic acid oxidizes quickly when it’s exposed to air and light. Meaning, it has to be stored with utmost care. It can also cause irritation and redness at high concentrations. If you have sensitive skin, look for formulas with 10-15%.

 

 

MAGNESIUM ASCORBYL PHOSPHATE

This form of Vitamin C will also boost collagen and elastin, brighten and even skin tone, and has positive effects on hyperpigmentation. Although less is known about it, we do know that it’s more stable than L-Ascorbic acid and won’t rapidly oxidize when exposed to light and air. It’s also gentler on your skin and can be used in concentrations ranging anywhere from 1-20%.

 

 

SODIUM ASCORBYL PHOSPHATE

A combination of ascorbic acid, phosphate, and salt, this is a less-active form of ascorbic acid that’s perfect for those with sensitive skin. Like Magnesium Ascorbyl Phosphate, it’s also more stable for use in skincare. It’s a great antioxidant that improves your skin’s defence against environmental stressors and it also boosts collagen production, evens skin tone, and caries antimicrobial benefits.

 

 

CALCIUM ASCORBATE

Because it’s got calcium in it, this form of Vitamin C has benefits for bones, cartilage, and tissue that you just won’t find in the others. Besides that superpower, it’s also a formidable antioxidant that promotes the production of collagen to reduce the appearance of fine lines and wrinkles as well as eliminate dark spots. This is an excellent option for mature skin.

 

 

ASCORBYL PALMITATE

One of the mildest forms of Vitamin C, it still packs an anti-aging punch – and it does so without irritating sensitive skin. Ascorbyl palmitate is able to penetrate the deepest layers of skin tissue to stimulate collagen synthesis, and that provides visible improvements to skin texture and tone.

 

However, like ascorbic acid, this form of Vitamin C can break down when it’s exposed to heat and oxygen. So it’s imperative that it’s packaged and stored correctly.

 

 

 

WHAT DO VITAMIN C SERUMS TREAT?

Vitamin C Serums treat a variety of skin concerns, but here are the main ones:

 

 

VITAMIN C FOR ACNE

Vitamin C doesn’t treat acne directly, but it does remedy the consequences of this skin concern. In fact, there are a couple of ways Vitamin C for acne works. Mainly, it reduces redness and inflammation as well as helps fade post-breakout scarring.

 

 

EFFECTS ON REDNESS

Your immune system has its own ways of dealing with acne – the problem is, sometimes this process results in redness that can make your skin look just as bad as it does during a breakout.

 

Leukotrienes are the inflammatory chemicals produced by your immune system to kill acne-causing bacteria. But acne-causing bacteria have a decoy system that causes those chemicals to redirect towards the skin, causing it to turn red.

 

Vitamin C works to calm the immune system rather than stimulate it, preventing the destruction of healthy skin and redirecting its efforts toward the bacteria in your pores. In addition, Vitamin C strengthens the lining of your capillaries (microscopic blood vessels that bring oxygen and nutrients to your skin). The redness of breakouts is usually generated at this layer of the dermis. So, by strengthening your capillaries with Vitamin C for acne, you minimize leaks of bright red blood vessels.

 

 

EFFECTS ON SCARRING

Luckily enough, many of us grow out of our acne stage. But that doesn’t help the scars that it tends to leave behind. Vitamin C helps with the body’s natural healing process, so it can boost the healing process for acne scars and other blemishes quickly and effectively. It also boosts cell regeneration and the formation of new skin, which will reduce the appearance of any scars.

 

 

VITAMIN C FOR FREE RADICAL PROTECTION

Free radicals are molecules produced by your body as it breaks down food, but they’re also triggered by things in our environment such as UV rays, pollution, and tobacco smoke. When you don’t have a good balance between antioxidants and free radicals, the latter can attack your skin and cause fine lines, wrinkles, dark spots, sagging skin, dullness, and uneven skin tone.

 

Vitamin C is one of the best antioxidants there is. It breaks down free radicals, converting them into harmless compounds and also clears toxins from your skin.

 

 

VITAMIN C FOR HYPERPIGMENTATION

Hyperpigmentation comes in many forms: sun spots, age spots, brown-ish marks or ‘the mask of pregnancy’. All of these manifestations are caused by accumulations of melanin and they make you look older because your skin tone and texture appear (and in some cases are) uneven and dull.

 

UV exposure is the most common cause of discoloration. UV rays stimulate pigment cells in our skin and cause our bodies to produce melanin. But there are, of course, other reasons as well. Heat, hormones from birth control or during pregnancy, and injury to the skin are all contributors to dark spots. And, while all skin tones can experience hyperpigmentation in its various forms, people of Asian, Mediterranean, and African descent tend to be more sensitive to developing discoloration.

 

Vitamin C gently exfoliates your skin and encourages cell regeneration. By allowing dead skin to shed and be replaced by new skin, hyperpigmentation tends to fade. Vitamin C also blocks the enzyme known as tyrosinase which is a key component in the production of melanin. By blocking tyrosinase you prevent discoloration from occurring, leading to a brighter and more even skin tone. As we’ve already mentioned, the best vitamin C serums will also help speed up the healing process, taking care of any injury-caused hyperpigmentation, and also treats redness that may be contributing to an uneven skin tone.

 

When using Vitamin C for hyperpigmentation, one must practice patience because most products will take at least 4 weeks to start working. You also can’t expect to use a vitamin C serum for hyperpigmentation while continuing to bask in the sun’s rays – you should be staying out of the sun and wearing a strong broad-spectrum sunscreen or you’ll be counteracting any benefits of the treatment.

 

 

VITAMIN C FOR FINE LINES & WRINKLES

Vitamin C serums have an answer for everything skin-related. By promoting the production of essential proteins like collagen and elastin, the building blocks of your skin, Vitamin C helps prevent and treat fine lines and wrinkles. As we all know by now, our body produces less and less of these proteins as we age, but boosting their levels helps treat their appearance and also prevents their formation.

 

 

VITAMIN C FOR UV DAMAGE

A topical Vitamin C serum is pretty effective for protecting your skin from harmful UVA and UVB rays. While it shouldn’t replace the regular use of a good broad-spectrum sunscreen, it is an antioxidant that strengthens your skin and its ability to repel damaging environmental factors. And if you’re one of us “day-walkers” (aka pale people), Vitamin C can also help heal sunburns as part of its healing properties.

 

 

Vitamin C isn’t the only vitamin with skin-beneficial properties. Check out our guide on the most effective topical vitamins to learn about other antioxidants that can help strengthen and protect your skin.

 

 

WHAT INGREDIENTS WORK WELL WITH VITAMIN C?

Two heads are better than one and that’s true in skincare, too. Combining Vitamin C with other skin-beneficial ingredients can increase its efficacy and help you target more than one skin concern at a time. Below we’ve outlined two things you should consider adding to your Vitamin C treatment.

 

 

VITAMIN E

Like Vitamin C, this vitamin is an antioxidant. It increases the protective properties of vitamin C because it too fights free radicals and protects against harmful UV rays. Vitamin E can also help balance the production of sebum, ensuring your skin is properly hydrated from the outside in. When combined with Vitamin C, it boosts your body’s ability to heal and fight inflammation. Look for formulas that contain 15% Vitamin C and 1% vitamin E for best results.

 

 

FERULIC ACID

Found in the seeds of fruits as well as in some vegetables, nuts, and grains, Ferulic Acid is a very powerful natural antioxidant. Ferulic acid fights free radicals to a greater degree than the aforementioned and is able to destroy several different types of free radicals: ‘superoxide’, ‘hydroxyl radical’, and ‘nitric oxide’. This is probably one of the best natural tools for fighting wrinkles, especially when used with Vitamin C and E. Combining 15% Vitamin C, 1% Vitamin E and 0.5% Ferulic Acid makes Vitamin C 8x more effective. Look for a serum with these concentrations, or close to, to get the most out of your Vitamin C treatment.

WHEN SHOULD YOU USE A VITAMIN C SERUM?

The best Vitamin C serums can be used twice per day. At the very least, we recommend applying it after your morning cleanser and wearing it throughout the day. It’s best to apply the serum underneath your broad-spectrum sunscreen because, as you now know, it boosts the power of the sun protection agents in your sunscreen and wards off the damaging effects of UV rays.

 

 

HOW TO STORE VITAMIN C SERUM

With Vitamin C serums, refrigeration is a MUST. These serums oxidize quickly when they’re exposed to both light and air. By keeping it in a cool, dark place (like a refrigerator), you’ll help extend the shelf life.

 

Disclaimer: oxidized vitamin C isn’t dangerous, it just won’t be effective.

 

 

 

CHECKING YOUR VITAMIN C SERUM FOR FRESHNESS

You can check the serum’s pH levels every few weeks to determine how fresh it is. This is especially important when making your own serum or when using L-Ascorbic acid.

 

You can check the pH with pH strips. For serums using L-Ascorbic acid, the pH should be between 2.5 and 3.5. For serums using Magnesium Ascorbyl Phosphate, the pH should fall between 6.0 and 7.0.

 

If you notice that the serum is yellow/brown (and it was originally clear), it’s already oxidizing. You can make the decision to keep or throw it out, but keep in mind the oxidized Vitamin C is not as effective.

 

 

 

PERIOD OF EFFECTIVENESS

Vitamin C isn’t supposed to oxidize when it’s well protected from the elements. As long as you’re not exposing the bottle to heat or sunlight, you can keep Vitamin C serums for between 3 and 6 months before they need to be discarded.

 

 

 

RESULTS

In terms of how long they take to work, you can see results as quickly as 4 weeks if you’re using a Vitamin C serum regularly, but you’re more than likely going to have to wait at least 12 to realize its full potential. Keep in mind that the period may be longer if you need to get your skin used to the serum first – Vitamin C can sensitize skin so you should take your time working up to a daily application.

 

 

 

OTHER EFFECTIVE SOLUTIONS FOR HYPERPIGMENTATION

Vitamin C is a natural solution to many of the most common skin concerns. It works well, especially when combined with other ingredients, but we’d be remiss not to mention that there are other effective solutions that target the same concerns, and we think they’re worth your consideration.

 

 

EXFOLIATE

We don’t recommend physical exfoliation (i.e. using a granular product to rub away and remove dead skin). Instead, look into chemical peels are chemical exfoliants. These treat hyperpigmentation as well as the visible signs of aging like fine lines and wrinkles.

A chemical peel will literally peel away and shed the top layers of the dermis. In so doing, these cosmetic procedures boost cell turnover, reveal fresh layers of skin and, in turn, help fade hyperpigmentation.  For all the rejuvenating benefits of chemical peels have a look at our in-depth article.

 

 

RETINOL

Retinol is a derivative of Vitamin A. It’s a topical solution for combating fine lines and wrinkles, improving skin texture and tone, increasing skin firmness and reducing breakouts. With minimal long-term side effects and fairly quick results, Retinol is a powerful antioxidant with a host of benefits for your skin.

 

There’s a lot to know about retinol and its different forms. Our guide on how retinol improves skin will help you navigate everything you need to know about this form of vitamin A and what it can do for your skin.

 

 

SUNSCREEN

The sun is one of the main contributors to premature aging. UV rays and the damage they cause manifest in uneven skin tone as well as fine lines and wrinkles. By protecting your skin with sunscreen, you create a barrier between your delicate skin and the sun, minimizing any prospective damage it can cause.

 

It’s not enough to pick up a sunscreen from the shelf and think you’re protected. There are good ingredients and bad sun protection ingredients.  We can help you figure all of that out with our guide to understanding your sunscreen.

 

 

 

FINAL THOUGHTS

Vitamin C serums are an excellent addition to your skincare routine on their own or, even more so, when combined with other powerful antioxidants. Not only does it act as a treatment for discoloration, acne, and the damage caused by free radicals, but it’s also a great preventative treatment so you can stop the signs of aging before they start. With Vitamin C in your arsenal, you can be sure your skin is protected and looks the best that it can be.
