There’s no doubt you’ve heard of Vitamin C Serum. whether in a conversation with your friend or read about it in one article, or even heard your dermatologist recommended it for being a magical product with miraculous effects on the skin.

What is Vitamin c serum? & What is it used for?. When should I use it & how?. We read all the questions whirling through your mind, And we are here with the answers.

What is Serum Vitamin C Serum?

Vitamin C Serum is one of the best antioxidants that fight skin aging, ensuring longer intervals and extended brightness for the skin cells.

Although sunblocks can indeed form a barrier isolating the skin from UV rays. However, it only blocks 55% of the harmful rays. This is why it’s crucial to include antioxidants, combined with sunblocks, to protect the skin.

Even though we can obtain Vitamin C from food intake, unfortunately, a minute amount only can reach the skin. That said, it is vital to directly apply it to your skin to promote collagen formation and lighten the skin faster.

Who should use Vitamin C Serum?

Vitamin C Serum is known for protecting the skin from many problems, such as sunburns, hyper-pigmentation, wrinkles, fine lines, dryness, and intoned skin. If you have any of the previous problems, think of Vitamin c serum as your magical solution. And if you don’t, experts still recommend using it as it has a fundamental role in fighting premature aging.

This is why it is important to understand vitamin c serum effects and benefits for the skin.

What are Vitamin c serum benefits for the skin?

It has three main benefits you can’t live without

1_ Antioxidant= younger skin

Each day your skin gets exposed to the sun, it takes a further step towards aging. UV rays (the harmful rays) form particles called “ free radicals” on the skin surface. These free radicals cause changes to cellular DNA and proteins. These changes destroy collagen.

Vitamin C is important in preventing premature aging for your skin cells and improving wrinkles, by boosting collagen formation and isolating your skin from UV rays.


Collagen is the responsible protein for giving your skin that tight look and maintaining its youth. It has an important role in preventing scarring and accelerating wound healing. If you suffer from old acne/ wound scars, it is important to include vitamin c serum in your skin routine.

3- Lessens Melanin formation - more toned skin

A lot of women suffer hyperpigmentation and uneven skin tone. Vitamin c serum has a major role in reducing melatonin production, which is the compound responsible for skin pigmentation. That is why vitamin c serum is efficient in the treatment of dark spots, sun spots, acne scars, and hyperpigmentation.

The best use for the best result

1- Can’t I apply the Serum during the daytime?

One of the biggest misconceptions regarding vitamin c serum is that we cannot apply it in the daytime for fear it would oxidize on our skin. This is not true. While you can use the serum twice a day, in the morning and in the evening, it is better to use it in the daytime. As it mainly works on combating the free radicals we previously discussed, these free radicals form in daylight, while being exposed to the sun.

Feel safe to use the serum in the morning without any concerns. As long as you are protecting your skin with a layer of sunblock before going out.

2- What is the ideal percentage of Vitamin C should be added to the serum?

One of the most confusing things when picking the right serum is vitamin C percentage. While countless people falsely believe that the higher vitamin c percentage a product contains, the more efficient it will be, it is apprehended that there is a limit for adding vitamin C; ranging from 8% to 20%. If higher than 20%, it will cause skin irritation. If lower than 8%, it won’t have any efficiency.

Always start with a low percentage to help your skin slowly grasping it without developing any allergic relapse.

3_ Does Vitamin c serum cause acne? Is it suitable for acne-prone skin?

Recent studies proved that Vitamin c serum has a therapeutic effect on acne as it reduces erythema (One of the factors behind the emergence of acne). It also targets free radicals, which are the main reason for acne appearance.

However, it is shown that some skin may develop acne in response to serum applications (especially combined and sensitive skin). If this happened to you, no need to worry. Just try to introduce the serum gradually to your skin by using it once a day, in minute doses, until your skin gets used to it.

4_ Why does Serum change its color and smell after a while?

Vitamin c serum is one of the most sensitive formulas that should be handled carefully. As it is highly oxidative, whether by air or sunlight exposure.

While most serums expiry date could last to three years. Most doctors advise you to get rid of your serum if it has been six months since opening the container.

The reason behind this is that any product has what is termed as “the shelf life”. Which starts from the day you use it. Since Vitamin C serum is a highly sensitive compound, it is familiar for its ingredients to start reacting gradually once the container is open.

If you’re intermittently using your serum, it is likely to notice a slight change in its color or odor after a while from buying it. Kindly know that this product isn’t designed for long shelf keeping without being used. 

If you’re about to try Vitamin C serum, you shall use it daily to ensure the ingredients are reacting on your skin surface, not inside the container. This way, you will avoid the risk of the color change since you will finish it in a few weeks anyway.

5- How to avoid color and odor change of the serum?

Store it properly, in a closed drawer away from heat and direct sunlight, you can keep it in your fridge and try not to leave it unused for long periods.

6- Is it suitable to use it around my eyes?

You can use it under your eyes with no fear (however, never put it above your eyes). Just keep in mind using few, very few amounts when dealing with this delicate super sensitive area of the face.

However, experts recommend choosing another product for such an area, look for a lighter, more hydrating product that contains some vitamin c in it.

7- When exactly should I be starting introducing vitamin c serum to my skincare routine?


Right now! Even if you’re still in your early twenties, there is no harm using the serum since its main objective is boosting collagen formation. You may have a soft, wrinkle-free skin now, but soon enough, before even noticing, they will start invading your skin. Remember, the best way to fight wrinkles is by preventing them from the first place.

8- when should I expect to see results?

Vitamin C serum is one of the products that show a long term effect. This is why it is important to maintain regular use of it. Look At it as a favor you’re doing yourself in your twenties, only to gain results in your late thirties.

However, if your goal is to reduce pigmentation and to unify your skin tone, all results show that this effect starts yielding after 4 to 6 weeks of continued use.
