When we are young we don’t pay too much attention to our skin as it’s quite flawless, plump and blemish free. Keeping it that way can be difficult, but there are many good inexpensive vitamin C serums that are able to improve complexion, fight dark spots and improve the skin’s firmness by helping boost collagen synthesis.

As we enter our teen years, damage starts to accumulate, we start getting acne, and if that wasn’t bad enough, signs of sun damage start to show with the development of fine lines, hyperpigmentation, and other skin problems.

It’s difficult to hold back the signs of aging but with proper sun protection and a good skin care regimen, it’s possible to maintain youthful-looking skin.

While there are amazing vitamin C serums available that have proven anti-aging effects, they can be very expensive due to patented formulas. For example, SkinCeuticals products are highly recommended by dermatologists because they have clinical evidence from patients which show their efficacy.

Thankfully, in recent years there have been many copies created which have similar ingredients as the high-end products. However, instead of using Ascorbic Acid, which is highly susceptible to oxidation, cheaper serums use a more stable form of Vitamin C.

This does mean that they aren’t as powerful as serums containing Ascorbic acid, but there is clinical evidence which shows that Ascorbyl Sodium Phosphate has many positive effects on the skin.

If you’re in a bit of a rush and can’t read the whole review, here are 4 great serums that you ought to check out!

Rank Vitamin C Serum Description
#1 Seoul Ceuticals – Korean Skin Care K Beauty Designed for people who want a high-quality but cheap serum that is suitable for all skin types.

Why should you use a Vitamin C serum?

Collagen is what keeps everything together! It is the foundation or matrix that keep holds the structure of the skin keeping it looking youthful.

It provides firmness to the skin, which is gradually lost over decades of sun exposure, stress, and other insults from the environment.

Vitamin C has been clinically proven to boost collagen synthesis for more younger looking skin even at just 5% concentration.

It can be used as both a corrective and preventative treatment to help the appearance of fine lines and wrinkles, but it can also help lighten hyperpigmentation, red marks, and improve skin tone.

Unlike retinoids, vitamin C is not harsh and there are little to no side effects from applying daily to the face.

What’s the difference between budget and high-end Vitamin C serums?

If you’re going for a cheap serum, you’ll normally see an ingredient called Sodium Ascorbyl Phosphate (SAP) which is a stabilized form of vitamin C.

L-Ascorbic acid (AA) is often used in more expensive products, but you can find them in cheaper versions as well. The problem with the cheaper versions is that it can become oxidized and do more harm than good unless properly stabilized.

For this reason, if you’re not going to spend a lot of money on a high-quality and clinically tested serum, I recommend products containing SAP instead.

Vitamin C serums can help block sunburn cell formation and help reverse photo-damage from the sun. However, it’s even more effective when combined with a good sunscreen.

Added Ingredients Make Vitamin C Even More Powerful

As already mentioned, the addition of vitamin E, Ferulic acid, and Phloretin can significantly improve the efficacy of these skin serums in treating a wide range of skin problems. Below I will briefly touch on each ingredient that is included in some of the vitamin C serums that I recommend in this article.

Ferulic Acid

Ferulic acid is found in many different places, it’s an organic compound that is in the cell wall of plants. You can find ferulic acid in the seeds of certain fruits like apples and oranges. You can also find it in certain vegetables and nuts. By itself, it is a very effective antioxidant.

It not only helps to stabilize vitamin C but also has the power to preserve the integrity of our skin by mitigation radiation damage from the sun.

Vitamin E

Vitamin E in serums is an important addition for several reasons. One reason is that it helps keep the skin moisturized and helps prevent inflammation and free radical damage. Vitamin E also helps stabilize the vitamin C. Vitamin E also allows the serum to be spread across the skin better.

Both of these ingredients also work synergistically through the donation of electrons, going through a process of “recycling” whereby Vitamin C donates an electron and causes vitamin E to become stable again.

Hyaluronic Acid

We naturally produce Hyaluronic acid, which basically allows us to hold more water in our skin making it look plumper. It has many benefits for improving the skin barrier as well as having a calming effect on the skin by reducing irritation from the environment. Hyaluronic acid also is good to reduce inflammation and improve the healing capacity of the skin.

Main Benefits of Using a Vitamin C Serum

There are many different benefits of using vitamin C to protect and improve overall skin health and function. Below are some of the main benefits you’ll notice if you use a serum every day.

Increased protection from sun damage.

Vitamin C is a powerful antioxidant that soaks up reactive oxygen species (ROS), which can be very damaging to the collagen that keeps our skin together.

When we are exposed to UV rays, pollution, and other environmental factors, the level of reactive oxygen species increases in the skin, leading to mitochondrial damage and up-regulation of enzymes which degrade our elastin and collagen.

Vitamin C serums have been shown to prevent dimer formation almost completely, thus lowering the risk of skin cancer.

When you combine sunscreen with vitamin C, you have even greater protection from skin cancer and slower skin aging.

Increases collagen synthesis in the skin and protects elastin

Vitamin C serums have been shown to affect the rate that we synthesis collagen in our skin. When we are young, collagen synthesis is at a high level, but as a person ages, the rate at which collagen is laid down becomes sluggish.

Not only that, the collagen tends to be laid down incorrectly and disorganized, which leads to the formation of the lines and wrinkles people see in their 20s and beyond.

By using a Vitamin C serum, you will protect the elastin that you have, so your skin will snap back into position more quickly, and keep your skin tight, while also improving collagen synthesis so fine lines and wrinkles are gradually filled in.

There are have been multiple long trials using Ascorbic acid for treating fine lines, wrinkles, and hyperpigmentation, but Sodium Ascorbyl Phosphate has only been tested in-vitro and in animals. And you need a higher concentration of SAP to have a similar effect of Ascorbic Acid.

Studies show a significant benefit after just 12 weeks. But improvements can continue up to a year and beyond.

The percentage of people who benefit from using these skin serums is thought to be about 80% in terms of increased collagen synthesis and objective improvement in lines and wrinkles. However, all people who use a vitamin C serum as a preventative should benefit from enhanced photoprotection of their skin.

Reduces redness, inflammation, and other common skin complaints such as acne

Vitamin C is also great for people who have inflammatory skin conditions like acne. It helps calm the skin, and improve overall skin redness over time. It also has antibacterial and anti-inflammatory benefits.

Any time there is inflammation of the skin, there is the potential for damage. By limiting the inflammatory reaction to bacteria and other skin problems, you also reduce damage and prevent age-related skin problems.

Improves the healing capacity of the skin

As you get older, the healing capacity of the skin is greatly reduced. If you’re old enough, you’re probably aware that as a kid you would heal very fast from little cuts and wounds, but when you’re older this is no longer the case.

By using vitamin C serum on your face, the everyday damage that is inflicted on your skin will not only be reduced but also the rate at which skin repairs itself will be increased.

Prevents sun spots, hyperpigmentation, and other skin discolorations

Every day living, just going out int he sun can cause things like liver spots or sun spots, hyperpigmentation from increased melanin production.

Vitamin C is able to decrease melanin production significantly, especially when combined with other ingredients such as ferulic acid and phloretin.

The main cause of much of the discoloration that people experience is either from acne or from the sun.

To get the biggest protection from skin discoloration, it’s recommended that you also use a high SPF sunscreen as well, especially in the summer.

They help reduce under-eye puffiness and under-eye circles

If you’re up all night and getting a bit older, you’ll start to notice that dark circles from under the eyes. Vitamin C can help by reducing inflammation, evening out skin tone and brightening up the skin.

Using vitamin C with a good Eye Balm would be even more effective because the eye area tends to be drier and more easily damaged than the rest of the face.

The first signs of aging usually appear around the eyes, even as early as late teens and early 20s. So it’s important to use skin serums under the eye from an early age to prevent the development of fine lines, crows feet, and under-eye circles.

Your skin glows

Anyone who has ever used a good vitamin C serum before knows that one of the first benefits you see is glowing skin. This effect can appear even within a few days of using the serum, and you’ll never want to go back to not using it.

You’ll look younger for longer

All of the above benefits culminate into one thing: you’ll probably end up looking a lot younger than your age and staying that way for a longer time than you would have if you hadn’t been using these skin serums.

Frequently asked questions about Vitamin C

Can vitamin C serum burn skin?

When applying L-Ascorbic acid, you might notice a slight stinging sensation. This is completely normal and after a few applications, the effect usually goes away. These products contain Sodium Ascorbyl Phosphate, which should not cause any irritation.

Does vitamin C serum lighten skin?

Vitamin C is known to inhibit an enzyme called tyrosinase, therefore it has the potential to lighten skin tone and lighten freckles and other marks on the skin. Please allow at least 3 months to see an effect.

Best time to use vitamin C serum?

Once you apply vitamin C it is absorbed and is effective for as many as three days. It acts as an antioxidant in the skin and mops up free radical damage, inhibits inflammation and increases collagen synthesis.

It also acts as a mild sunscreen by itself but is usually more effective when combined with other ingredients such as vitamin E and Ferulic Acid which the Seoul Ceuticals Korean Skin Care product contains.

Most people prefer to use these serums in the morning after washing.

Does vitamin C serum help acne?

Vitamin C serum can improve the healing time of acne marks as well as prevent acne from forming. It can also help reduce any inflammation and reduce the severity of breakouts if they do occur. By itself, vitamin C is unlikely to cure acne but may mitigate the damage that acne can cause to the skin like hyperpigmentation and scarring.

You might also want to go with Sodium Ascorbyl Phosphate instead of L-Ascorbic acid, as this is less irritating on the skin, and has some clinical research on its positive effects on people who have acne.

How long to wait for results?

You should give it a few months to some improvement. Many people notice a glow the first time they use a vitamin C serum, and this can appear just days after using it. Over time you’ll gradually notice changes in how your skin looks and feels.

To see faster improvements, you can also make sure that you are protecting your skin in other ways like using a powerful sunscreen and also use a good moisturizer at night.

You also want to make sure that you are using the serum correctly (see the video below).

Ways to improve your results

  • Use sunscreen every day and limit sun exposure
  • Make sure that the serum has not been oxidized (it’s not dark yellow)
  • Make sure that you apply the serum every day
  • Make sure that you spread the serum evenly over the entire face, but avoiding the eyes

Note: Over time vitamin C will change color and will lose its potency. I have found that storing it in a cold place will slow down this oxidation process and it will barely change from the moment I open it to the last drop.

Will taking Vitamin C supplements to improve my skin help?

Many people believe that taking vitamin C orally will help improve their skin, but unfortunately, the concentration needed to have any effect is much higher than what you will obtain with supplements.

Will applying citrus fruits to my face help the same as a vitamin c serum?

Applying a citrus fruit to the face will not give you the same benefits as using a concentrated vitamin C that is specifically designed to penetrate into the dermal layer at effective concentrations. Also, applying citrus fruit can be generally irritating to the skin because of the pH level and other ingredients.

Can you use vitamin C after having laser treatment?

These serums are suitable for people who’ve had laser treatment. Although you should always consult with your physician beforehand.

How To Use Vitamin C Serum On Your Face

To make vitamin C serum more effective you want to make sure that you wash your face and exfoliate occasionally to remove dead skin. You want to go from using the lightest product first, to the heaviest and thickest.

So after you clean your face with your cleanser, you should then use the dropper and use a small amount and rub in gently (see video below).

Wait until the product dries and then use sunscreen for added photoprotection. The best results will be seen when you are also using sunscreen.
