The one condition vitamin C can definitely treat is vitamin C deficiency.

Those with a severe dietary deficiency of vitamin C can develop scurvy, characterized by bruising, bleeding gums, weakness, fatigue, and rash.

Outside of a known deficiency, vitamin C is believed by some to aid in the treatment or prevention of numerous diseases, including colds, asthma, bronchitis, cancer, chronic pain, cataracts, gastritis, glaucoma, heart disease, high blood pressure, osteoarthritis, and Parkinson’s disease.

Although the evidence supporting these claims is generally weak, there have been several promising findings in recent years.

Can They Be Combined

Theres a big difference between using retinol and vitamin C concurrently, and combining the two for use simultaneously. In addition to the irritation risks of starting two different skin treatments at the same time, there are also potential problems from applying them at the same time.

Conventionally, this has been advised against for a few reasons. First of all, vitamin C and retinol have different solubility requirements. Vitamin C is soluble in water, whereas vitamin A compounds are soluble in oil.

Used separately, topical creams and serums dont cause each other problems, but if youre layering the two, it can make both treatments less effective.

In the past, there were also assumptions about the efficacy of these treatments that had to do with pH levelsthey were more effective at conflicting pH levels, and combining two treatments could make for a less effective experience.

These days, pre-combined cosmetic formulations have been shown in limited studies to offer a stable, effective solution for using both vitamin C and retinol at the same time.

A 2012 study noted some promising results, though it noted a lack of data or explanation as to how stability is achieved in these cases. In other words, research is ongoing as to whether combinations are an alternative to two separate treatments.

What Does Vitamin C Serum Do

Vitamin C serum is touted to be one of the best anti-ageing ingredients. Safe for all skin types, Vitamin C serum has several benefits. It hydrates the skin, brightens the complexion, treats inflammatory skin conditions, fades hyperpigmentation, reduces the appearance of dark circles, promotes collagen production, prevents the skin from sagging, protects it against sun damage, soothes sunburns and heals wounds. Phew! Now thats a long list of benefits.

Benefits Of Vitamin C For Skin

Vitamin C is an impressive skincare ingredient that is shown to be effective in the following areas:

  • Protects against environmental stressors: As an antioxidant, one of vitamin Cs main functions is protecting the skin. “Normal cellular processes, as well as environmental insults like ultraviolet light and pollution, create free radicals in the skin,” Herrmann explains. “Free radicals are inherently unstable molecules that damage cells, promoting skin dullness, wrinkles, and even cancers.” Guanche adds, “Vitamin C is an antioxidant, which means that it can protect to skin from damaging free radicals caused by UV exposure.” By scavenging these free radicals, vitamin C protects the skin, keeping it healthy and improving visible signs of aging.
  • Promotes collagen production: Vitamin C also plays an important role in collagen synthesis. “Collagen gives our skin support and structure, and as it degrades with age, we begin to notice wrinkles and lines,” Herrmann explains. “Vitamin C is a necessary cofactor for building collagen bundles, without which this process halts.”
  • Lightens brown spots: Vitamin C is also helpful in lightening unwanted brown spots and post-inflammatory hyperpigmentation, or decreasing brown discoloration by blocking the pathway of pigment synthesis, according to both Herrmann and Guanche.

How To Use A Vitamin C Serum And Reap Its Benefits

Saedi says to apply a few drops of serum to your face after you wash and dry it. A little bit goes a really long way, she says. She recommends putting it on every morning, all year round. It has some benefits with sun exposure so it helps to apply in the morning as the first layer of protection, she says. She says to then layer on your moisturizer and sunscreen. Serums are better than adding drops of vitamin C boosters to your moisturizer, Saedi says. They may not be as potent as serums themselves and mixing them with moisturizer may dilute the effects.

Store your bottle in a cool, dark place away from extreme heat, such as a bathroom cabinet as opposed to on your counter. Storing a vitamin C serum correctly is integral to its success, Schlessinger says. A good rule of thumb is to toss the serum six months after its been opened and to keep the serum in a cool, dark place. If youre using it according to the instructions, itll likely be gone before the six months is up. If not, youll want to throw it out. When vitamin C is used past its shelf life, it can actually have negative effects, Schlessinger says. More on that next.

Retinol And Vitamin C In Your Skincare Routine


While some skincare ingredients are better used in combination with others, some are powerful enough to benefit the skin on their own. Retinol and Vitamin C reside in both of these categories.

Retinol as a sole treatment is extremely effective for stimulating collagen production, treating acne, tightening the skin, softening skin texture and leveling skin pigment. Vitamin C can single-handedlybrighten the skin,shield the skin from pollutants andsun damage,treat hyperpigmentation, andreduce skin inflammation and redness.

Used separately, these two ingredients can target specific skin conditions but when used together, Retinol and Vitamin C create the ultimate skin-beautifying duo for any skin type. Before we divulge the benefits of using this powerful skincare combination in unison, it helps to understand why and how these two ingredients work so well individually.

What To Look For

You can maximize the benefits of vitamin C by combining it with other antioxidants. This works best with vitamin E and ferulic acid, says Chapas. Together, they have optimal absorption benefits when it comes to anti-aging, skin brightening, and protection against free radical damage.

It also plays well with vitamin B and hyaluronic acid. However, do not mix vitamin C with a retinol or niacinamide, because the pH levels are incompatible, says Wexler. If you want to use both, she suggests waiting half an hour between applications.

Also worth noting: Vitamin C is notoriously prone to oxidizing. It can break down when its exposed to light or air, says Chapas. Always check expiration dates on your products, and if you notice a sour smell or discoloration, its most likely breaking down.

What Effects Does Niacinamide Ascorbate Have On The Skin

How To Use a Vitamin C Face Serum

Currently, the research that has been conducted on the dermatological effects of niacinamide ascorbate suggests that it is safe to use and still works to brighten the skin. Research has also shown that this complex is easily reversed and separated.

This is because niacinamide ascorbate forms most easily at a pH of 3.8. Although the surface of our skin is acidic, the pH becomes less and less acidic as you move to each deeper layer eventually reaching a neutral pH of 7. So, as niacinamide ascorbate penetrates the skin, the weak bond holding niacinamide and L-ascorbic acid together breaks and youre left with niacinamide and L-ascorbic acid again.
