Share this:

Younger-looking skin, reduced fine lines and wrinkles, increased radiance… are you tempted? If so, you might want to consider vitamin C serum for your face.

Vitamin C serum is an effective facial product. It improves your skin’s elasticity, brightens skin tone, and helps prevent visible signs of aging. It can also protect your skin from sun damage and pollution by fighting free radicals.

Vitamin C serum can do wonders on your face and this article explains the benefits, side effects, and the right use of vitamin C serum for your face.

What Is Vitamin C Serum?

Vitamin C serum is a facial serum that exfoliates, moisturizes, and rejuvenates your skin. It is a powerful antioxidant that helps protect your skin from free radical damage caused by UV rays, pollution, and cigarette smoke.

The best vitamin C serums will help to improve the appearance of your skin by promoting collagen production. Vitamin C serums can also help minimize the appearance of age spots, balance moisture, and add a healthy glow to your complexion.

Many serums use a combination of vitamin C with other antioxidants, such as vitamin E, green tea extract, or aloe vera that work together to fight aging signs. These ingredients also help to protect the skin from sun damage and other environmental stressors.

In addition, some vitamin C serums contain hyaluronic acid, which is a great moisturizer and can hold up to 1000 times its water weight. Hyaluronic acid in a serum will help your skin retain moisture, thereby keeping your skin hydrated.

Vitamin C Serum for Face Benefits

1. Heals Damaged Skin

Vitamin C serum is an excellent remedy for dry, rough, wrinkled, and damaged skin. It not only treats these problems but also helps to prevent them from occurring again.

The application of vitamin C serum helps in maintaining the elasticity of damaged skin, making it look young and supple.

2. Increases Elasticity

This serum works by increasing the production of collagen in the skin, which increases skin elasticity. The increased elasticity makes the skin appear firmer. It also helps to firm up loose facial tissues like jowls, cheeks, and forehead.

3. Improves Blood Flow

Vitamin C serum also increases blood flow to the facial tissues. The flow of blood brings oxygen to cells that need more oxygen to heal faster and remain healthy. This improves circulation on a cellular level and results in a fresher-looking complexion.

4. Fights Against Free Radicals

Free radicals are damaging molecules produced by UV rays from sunlight and pollutants in the environment that cause premature signs of aging, such as wrinkles. Topical vitamin C serum can help neutralize these free radicals before they cause damage to your skin cells.

5. Treat Acne and Blemishes

Vitamin C has anti-inflammatory properties, which makes it an effective acne treatment. Vitamin C serum with a concentration of at least 5% can help fade blemishes and brighten skin. You can also use it on acne scars to help fade them faster.

6. Protect Against Sun Damage

Studies have shown that vitamin C may protect against sun damage, including damage caused by ultraviolet radiation (UVA) rays in particular. It’s not a replacement for sunscreens, but you can use it with your regular sunscreen to boost its effects.

7. It’s a Potent Anti-ager

As you age, the collagen and elastin in your skin break down and allow for wrinkles and fine lines to form. Also, there’s an increase in free radicals due to pollution and other external factors which can also damage your skin’s cells.

When you apply vitamin C serum, it helps restore collagen and elastin, which in turn reduces aging signs. And since vitamin C is a powerful antioxidant, it fights free radicals before they cause premature aging.

8. Lightens Pigmentation

The term ‘lightning’ is used to describe the treatment of hyperpigmentation; this includes melasma, freckles, age spots, and sun damage.

The vitamin C present in the vitamin C serum reduces pigmentation and also helps in toning up your skin. You can also use vitamin C serum with other skin-lightening ingredients like alpha-arbutin, and kojic acid to help brighten your skin further.

9. Reduces Scarring

Scarring on your face can be embarrassing and negatively affect your confidence level, making it hard for you to walk around with your head held high. Vitamin C serum can help reduce scarring by repairing skin tissues.

Apply a vitamin C serum twice daily to help reduce the appearance of these marks. Scars from surgery or other serious injuries may require a different type of scar treatment, but vitamin C serum can still fade these scars over time.

At what Age Should You Use Vitamin C Serum?

According to Dr. Tsippora Shainhouse, MD, a board-certified dermatologist, the best age for someone to use a serum is in their early twenties.

By this age, you will likely have noticed some changes in your skin such as fine lines, scarring, or dark spots, as these are all common signs of aging.

Also, you definitely want to get used to using your serums before you hit your thirties, so you’re not introducing something new into your skincare routine once wrinkles set in.

The earlier you start using vitamin C serum, the better chance you have at keeping your skin looking young for longer.

Vitamin C Serum Side Effects

The most common side effect of topical vitamin C is irritation in the treated area. This irritation may be mild to severe and may include redness, flaking, dryness, and itching.

To prevent irritation, test a small amount of vitamin C serum on your skin before applying it all over. If your skin is sensitive, avoid applying other ingredients to the area where you want to apply the vitamin C serum.

If vitamin C serum does not improve your skin after months of daily use, discontinue use and see a doctor.

How to Use Vitamin C Serum Correctly

  • Cleanse your face thoroughly with warm water and apply a toner.
  • Using clean fingers, apply a small amount of serum to your face and neck. Because vitamin C serum is so concentrated, you only need 2-3 drops at a time.
  • Allow the serum to penetrate your skin for about 10 minutes before applying your favorite moisturizer. This will give the serum a chance to penetrate deeply into your skin without having to compete for absorption with other products.
  • Follow up with sunscreen. This is extremely important because the sun can damage your skin and cause premature aging. Apply sunscreen for at least 20 minutes before going outside so that it has time to soak into your skin.

If you notice any irritation on your face, stop using vitamin C serum immediately and consult with a dermatologist to determine why you are having an adverse

Things to Keep In Mind Before Buying Vitamin C Serum

Choose L-ascorbic acid

When choosing your serum, be sure that you’re getting L-ascorbic acid (pure vitamin C). Other derivatives such as MAP are popular because they’re less expensive and more stable than L-Ascorbic Acid, but they can’t penetrate the skin as effectively.

Pure vitamin C should have an LAA number after it; i.e., L-Ascorbic Acid 15%.

Focus on the concentration

For the full benefits of vitamin C serum, make sure you’re getting a quality product with a high concentration of vitamin C. Most serums contain between 10 and 20 percent vitamin C, but some sell products containing much lower concentrations.

Check the label to find out how much vitamin C you’re actually getting before you buy.

Check out the ingredients list

When choosing a vitamin C serum, experts recommend that you check out the ingredients list and select one with ingredients that match the needs of your skin.

If you have oily or acne-prone skin, look for an oil-free product that won’t clog pores. If you have dry or sensitive skin, look for a product with hyaluronic acid and make sure it doesn’t contain alcohol or fragrance.

Check the expiration date

You should always check the expiration date on your vitamin C serum because chances are if it’s expired, then the vitamin C has broken down and is no longer effective for brightening your complexion or fighting signs of aging.

Store properly

Vitamin C is an unstable ingredient which means if it isn’t packaged properly and/or exposed to high temperatures, it will break down into a useless product.

Ensure to keep your serum away from heat or direct sunlight, as this can cause it to lose its potency over time and may reduce its effectiveness in reducing skin problems.

Who Should Use Vitamin C Serum?

Treat yourself to a vitamin C serum if:

  • You spend a lot of time in the sun: If you live in a sunny area or spend most of your time outside, consider using vitamin C serum on your face to protect it from the sun’s damaging rays.
  • Your skin is showing signs of aging: Even if you’re young, you should start using a vitamin C serum if you notice fine lines, wrinkles, or any signs of aging on your face.
  • You want to incorporate anti-aging products into your daily routine: By adding a vitamin C serum into your daily routine, you’ll be protecting your skin while reaping the benefits of an anti-aging product at the same time.


When is the best time to use vitamin C serum?

The best time to use vitamin C serum is in the morning and at night after a thorough cleansing of your skin and before applying other products. Apply it by lightly dabbing the product onto your face until it absorbs into the skin completely.

Just remember that you will achieve the best results if you apply a moisturizer on top of this serum. Also, ensure to apply sunscreen to protect your skin from the sun’s harmful rays during the day.

Can you use vitamin C serum every day?           

Yes, you can. Applying vitamin C serum every day has many benefits for your skin because it contains active ingredients that work together to keep your skin looking its best.

However, use vitamin C serum with caution if you have sensitive skin. A good rule of thumb for sensitive skin is to start slowly and increase the frequency of use if you don’t notice any negative reactions.

Is vitamin C serum good for face acne?

Yes, it is. Vitamin C serum promotes exfoliation, helping to sweep away dead skin cells and reduce inflammation. It also balances moisture in the s so your pores don’t get clogged.

However, you should know that it takes time before you see results from using vitamin C serum for acne. That is because it needs time to penetrate deep into your skin layers before you start seeing any positive results.


Vitamin C is an anti-aging powerhouse that helps protect your skin from pollution and other environmental stressors. It works by reducing the damage caused by UV rays from the sun and by neutralizing free radicals in your skin.

The benefits of vitamin C for the face also include healing damaged skin, evening out skin tone, and treating acne. Given such benefits, vitamin C serum can be a great addition to your facial routine.
