Vitamin C serum works by going into the deepest layers of your skin to supply your skin with a high dose of vitamin C and other skincare ingredients.

You’ve probably heard a lot of the buzz about vitamin C serums and want to know what they are and how they work.

Vitamin C is an important nutrient needed by your skin to maintain good health. It does so much for your skin, and it’s important to ensure you are getting enough.

A good diet is one way to do this, but unfortunately, you may not be getting enough of this vitamin from your diet alone. Luckily, you can always go the serum route.

In this article, we will discuss how vitamin C serum works, the benefits of using vitamin C serum, and how you can use it for maximum results. Keep reading to find out.

What is vitamin C?

Vitamin C is a nutrient that is necessary for daily skin health. It is an essential vitamin that the body needs to produce collagen, a protein that gives structure to skin, blood vessels, hair, bones, and other tissues.

“This nutrient plays an important role in the immune system, metabolism, and cellular functions. It also prevents UV damage, and has antioxidant properties to help fight free radicals,” Dr. Tsippora Shainhouse, a board-certified dermatologist, says.

Vitamin C is usually found naturally in fruit and vegetables. However, if you’re not eating enough of them or if you have certain medical conditions, you might need to get them from supplements or skincare products like serums.

How does vitamin C serum work?

Vitamin C serum is one of the most potent and effective skincare products you can use.

It works by supplying your skin with high concentrations of vitamin C and other ingredients that can work to treat different skin concerns.

“Vitamin C works by activating the skin’s defenses. Once inside the skin, it neutralizes free radicals and other reactive chemicals in the skin. It also boosts the production of collagen, a protein that keeps skin firm and elastic,” Shainhouse explains.

Vitamin C serum work to treat dark spots, acne scars, fine lines, wrinkles, and other signs of aging skin. Moreover, a good vitamin C serum should contain vitamin E or other ingredients that’ll deliver maximum benefits to your skin.

Benefits of using vitamin C serum

It lightens skin

If you want to get rid of the dark spots on your skin, try using vitamin C serum. What causes these dark spots is excessive exposure to ultraviolet rays; this causes your body to make more pigment than usual.

When UV rays from the sun reach your skin, they trigger a response in your skin cells. This response causes your cells to produce more melanin, which can darken your skin.

Studies have shown that vitamin C can prevent melanin production in skin cells and stimulate collagen production, resulting in skin lightening after application over time.

It protects the skin from free radicals

As stated earlier, vitamin C is an antioxidant that protects your skin from damage by free radicals, which are unstable molecules that can damage DNA.

Free radicals build up in your body when you are exposed to pollutants, radiation, or any other source of toxins. They are also produced naturally in your body during everyday cellular processes.

Vitamin C works with other antioxidants in your skin to get to these free radicals and destroy them before they cause damage to your skin.

Reduces signs of aging

Even though we all want to be young, beautiful, and wrinkle-free forever, the truth is that aging is inevitable. Still, there are ways to slow down aging and even reverse it.

One such way is vitamin C serum. It helps in the production of collagen, a protein that helps keep skin cells firm. With age, your body produces less collagen, which leads to different signs of aging.

By increasing collagen production, vitamin C serum work to improve skin texture, which in turn reduces wrinkles and other aging signs. It also has brightening effects that help to reduce age spots.

Prevents sun damage

According to the American Academy of Dermatology, sun exposure is the number one cause of premature skin aging. However, using a vitamin C serum can help to prevent harmful effects from the sun’s ultraviolet rays.

Studies have shown that vitamin C can help reduce the severity of sunburn. These studies report that people who take high doses of Vitamin C over a while may also be able to prevent sunburn.

That is because vitamin C’s antioxidant properties help reduce damage from free radicals caused by sunlight. It also plays a role in collagen production, which strengthens skin, thereby reducing sunburns.

Improves skin elasticity

Skin elasticity describes the flexibility of your skin. It’s an important factor in how youthful and healthy you appear.

You lose skin elasticity as you age, and this loss can be sped up by UV radiation and other factors. If you notice an increase in wrinkles or dryness, it is time to purchase a vitamin C serum.

Other ingredients to look for in vitamin C serum

When shopping for vitamin C serum, ensure to look beyond the price tag and check the label to know what it is formulated with. Here are some essential ingredients to look for before purchasing this type of serum:

L-ascorbic acid

When purchasing a vitamin C serum, the first thing you need to look for is l-ascorbic acid. L-ascorbic acid is the most potent and active form of vitamin C. For your serum to be as effective as you want it, it has to contain this ingredient.

Ferulic acid

Ferulic acid is an antioxidant found in plants. Like vitamin C, it also helps protect your skin against oxidative stress and the damaging effects of free radicals.

Studies show that ferulic can increase the strength of vitamin C by up to 90%. This helps to increase the effectiveness of vitamin C on your skin.

Vitamin E

Vitamin E is a powerful antioxidant that can help fight free radicals and protect your skin from various environmental aggressors. When combined with vitamin C, it helps to improve skin texture, making it softer and smoother.


Glutathione is a potent antioxidant crucial for skin health. It helps prevent damage caused by harmful UV rays, pollution, and free radicals. It also protects healthy skin cells while helping to remove dead skin cells, which can clog pores.

Should you use vitamin C serum?

The best way to know if you should use vitamin C serum is to take this quick quiz.

  •   Have you had any sunburns in the last year?
  •   Are you above 20 years of age?
  •   Have you been skipping out on foods rich in vitamin C?
  •   Are you taking any medications that might interfere with vitamin C function?
  •   Does your skin have redness or discoloration?
  •   Do you have noticeable signs of aging, such as wrinkles, sagging, dryness, or dark spots?

If you answered yes to any of these questions, then you’re a great candidate for vitamin C serum.

Some people find they need to use it more often than others, so it’s always best to talk with your doctor before using a vitamin C serum.

How to use vitamin C serum

  • Clean your face with a mild cleanser and apply a toner to get your skin ready.
  • Get your Vitamin C serum and squeeze 1 or 2 drops onto your fingertips (this allows for easy application).
  • Apply the serum in an upward motion on your face (apply to your neck if desired).
  • Leave it to sit for 10 minutes, and then apply a moisturizer to seal in moisture for prolonged hydration.
  • Apply your favorite sunscreen and other skincare products if desired.

Apply this serum after cleansing but before your moisturizer or sunscreen so that it has maximum penetration into your skin.

Side effects of vitamin C serum

There are many benefits to using a serum that contains this vitamin. However, it’s important to know that there are also side effects that you should be aware of before applying vitamin C serum.

For instance, an overdose of vitamin C serum can lead to dryness and inflammation. It can also cause sensitivity and contact dermatitis if not properly mixed with other skin ingredients.

“Vitamin C may cause skin sensitivity to sunlight when used with retinol, so it’s important to wear sunscreen when using this product. The lack of scientific evidence on how much vitamin C penetrates the skin also merits caution,” Dr. Shainhouse warns.
