Vitamin C serum Buying Guide

Questions to Ask When Shopping for Vitamin C serums:

Vitamin C serums are the latest buzz in the skincare world. The benefits of this serum are well documented.

 But not every vitamin C serum is formulated well. This potent powerhouse of serum has many sensitive ingredients that must be balanced and combined well to achieve the right results.

 In this section, we look at factors that make up the right vitamin c serum for you. Hopefully, these will help you pick the best serum for you

1- What Do You Need The Vitamin C serum For?

  • Aging skin:

Vitamin C is a powerful antioxidant that helps fight free-radicals. Free radicals are created by unstable oxygen molecules that bear an uneven number of electrons, so it goes stealing electrons from other healthy molecules, causing your skin damage.

This process is what is known as oxidative stress, it leads to premature skin aging and can lead to conditions such as skin cancer.

 Vitamin C is a stable molecule that lends it’s electrons to unstable oxygen molecules, therefore, neutralizing free radicals.

Vitamin C also boosts collagen production, which helps keep your skin looking supple and young.


  • Oily Skin:

Vitamin C is vital for healing damaged skin. It fights acne and helps reduce inflammation caused by acne.

Vitamin C also helps speed up the exfoliation rate, giving you a youthful complexion. One of the greatest benefits of Vitamin C serum is its ability to control hyperpigmentation and produce a balanced skin tone.

 It fights this problem and also helps curb its future development. When looking for C serums, look for something non-greasy, which also contains Hyaluronic acid for the best results.

  • Acne Scars:

Vitamin C serum is essential at removing acne scars. It helps increase fibroblast cells that produce collagen. Increased collagen fills up depressed skin caused by acne scars. Hence repairing the skin and making it look more youthful and fresh.

At the same time, vitamin C helps brighten up dark spots caused by a previous acne bout.

 You want to look for vitamin C serums that are light, non-greasy, and which contain acne-fighting ingredients such as retinol or niacinamide. 

Note, however, that niacinamide deactivates vitamin C in its pure form, so it might make your C serum less effective.

  • Fine lines and wrinkles:

By stimulating the production of collagen, vitamin C helps firm up and smooth out fine lines that appear on the face, especially around the eye. Vitamin C also reduces redness, therefore improving discoloration often experienced under the eye. 

Vitamin C also helps reduce the appearance of wrinkles caused by premature aging of the skin due to sun damage. The boost in collagen helps plump up the skin.

  • Dark Spots:

Vitamin C is best known for brightening the skin up. It fades dark spots by inhibiting the excess production of melanin. It also helps heal acne scars, reducing dark spots.

  • Sun Damage

Vitamin C helps fight free radicals which cause skin inflammation resulting in skin damage. While you should still use sunscreen, vitamin C also helps fight against sun damage. If you already have sun damage, nothing will undo it better than a vitamin C serum

  • Dry skin 

Antioxidants help with hydration. They increase moisture retention and help brighten up dull-looking skin. Vitamin C serums, also boost the production of collagen which helps firm up the skin.

 If you have dry skin, you are looking for a vitamin C serum that has moisture increasing ingredients.

2- What Are The Ingredients?

There are various ingredients used to form Vitamin C serums, but the most important ones are the forms of vitamin c and the balancing agents. Here is a list of different ingredients:

  • L-ascorbic acid :

is a form of vitamin C that is highly absorbent. A study done to compare different forms of vitamin c shows that L-ascorbic acid had more absorption rate. When looking for a good vitamin c serum, you want to make sure that this is among the first five ingredients.

  • Concentration level:

Another thing to check is the concentration level of whatever form of vitamin C in your serum. Beginners and people with sensitive skin should use anything between 5 to 8 % of L-ascorbic acid concentration until the skin gets acclimated. However, higher concentrations of 10%-20% give better results.

  • Forms of Vitamin C :

Vitamin C can also come in tetrahexyldecyl ascorbate, sodium ascorbyl phosphate, and ascorbyl palmitate. However, when it comes to skin products, you want the best-formulated treatment. 

Most of these other forms of vitamin C are not stable enough and neither do they have as great an absorption rate as L-ascorbic acid.

With that said, however, some experts seem to believe that tetrahexyldecyl ascorbate is just as good as L-ascorbic acid if not better.

  • Natural vitamin C:

Other forms of vitamin C are sourced from botanical extracts. So, if you can’t find the chemical names mentioned above in the ingredients list, look for vitamin C producing botanicals. These include rosehip, pomegranate seeds, citrus fruits, sea buckthorn, and amla berries. 

  • Other ingredients:

Vitamin C serums are also combined with other ingredients that help stabilize it and add extra antioxidant power to the serum.

  • Vitamin E:

Vitamin E helps balance vitamin C. It is a powerful antioxidant that helps fight free radicals and has great anti-inflammatory properties. It’s an essential ingredient in cell health and ultimately skin health.

This aids in the maintenance of the skin barrier by strengthening it.

  • Ferulic Acid:

FA helps increase the effectiveness of vitamin C and E in the serum. It is an antioxidant derived from plants and food like oats, rice, and bran. It’s great at scavenging free radicals and helps decrease signs of aging, like fine lines.

Ferulic acid also helps lower Vitamin C’s PH to make it more skin-friendly.

  • Glutathione:

This is another powerful antioxidant that works well with Vitamin C. Lately, it has been gaining momentum for its antioxidant benefits and will soon be in many skincare products.

  • Ingredients to avoid:

Avoid fillers such as propylene and butylene glycol which are classified skin irritants. Avoid alcohol and harsh preservatives such as phenoxyethanol which can enhance eczema.

3- What Do Other People Think Of This Vitamin C serum?

Most C serums are sold online, this creates benefits like the ease of comparison and a wide range of products.

However, when purchasing things online you seldom get to test them before buying. Therefore, the best way to find out if a serum is effective or not is through other user’s feedback.

Check for product reviews to tell whether the C serum you are interested in will perform as advertised or not. 

Reviews vary, and if you are keen enough, you will get reviews that highlight your needs such as how suitable the serum is for particular skin types.

How To Properly Use a Vitamin C serum?

  • Test before use:

As with all other skincare products, it’s prudent to perform a skin test before using any Vitamin C Serum. 

Look for an easily concealable region of the skin to perform a patch test on. Select a small area, apply the serum, and wait for 24 hours to see if it reacts.

  • When to apply:

Vitamin C Serum is best applied after cleansing and setting the face before applying moisturizer.

 The rule of thumb when applying skincare products is to start with the lightest to the heaviest product. Serums with heavier textures can be used to spot treat as opposed to wearing all over the face.

  • Morning or evening or both?

There is an ongoing debate on whether to use Vitamin C serum both in the morning and evening. Some skincare experts recommend using it in the morning, or once a day, especially if it has a higher concentration like 15% or more. 

When starting out it’s best to use your serum fewer times to allow your skin to become acclimated to it. With that said, there are gentle serums that you can use both in the day and at night.

  • Packaging and storage

When purchasing Vitamin C Serum, ensure you check the packaging. Vitamin C degrades upon exposure to light, water, and air. As such, it’s often packaged in airtight tinted or opaque glass bottles.

 If it’s made out of ascorbic acid then it has to come in a dark-tinted glass bottle, plastic bottles can’t hold acids, because they will react. 

Depending on the company, C serums come in dropper, pumps, tubes, and, bottles. Pumps are more sanitary and less time consuming to operate. 

The color of the C serum is very important. C serums come in bright yellow and orange colors, if these colors turn dark orange, golden, or brown, then your C serum has gone bad. 

This happens because of poor storage. When vitamin C comes into contact with air, it oxidizes and turns a darker color, makes sure you store your C serum according to the manufacturer’s instructions.

Benefits Of Vitamin C serum?

  • Promotes Collagen Production :

    Collagen is the main structural protein in various connective tissues in the body. It plays a big role in strengthening the skin, providing hydration, and elasticity for the skin. 

    As we age, the body reduces the production of this important protein. Which might lead to dry flaky skin with wrinkles and fine lines.  

    The collagen helps firm the skin to prevent it from sagging, boost wound healing, and reduce fine lines or wrinkles on the skin. 

  • Applying concentrated levels of antioxidant-rich vitamin C will significantly boost the production of collagen in the body which has great benefits for our skin. 

  • Protect the skin from sun damage: 

Vitamin C is an antioxidant meaning that it naturally helps fight against free radicals. Free radicals are unstable oxygen molecules in the body that can damage cells causing aging and illnesses like cancer, heart disease, and dangerous other diseases in the body. 

Free radicals can be stimulated by ultraviolet light.

 The Antioxidants rich vitamin C protects the skin by neutralizing these free radicals. This helps protect your skin from harm caused by the sun. It also eliminates premature aging caused by exposure to UV lights. 

  • Fastens healing of sunburns:

    In addition to protecting your face from sun damage, Vitamin C also boosts the healing of sunburns. This is made possible because of the production of Collagen which stimulates wound healing and soothes your sensitive skin by reducing any redness, itching or burning, and other symptoms associated with sunburn.

  • Reduces inflammation:

    Vitamin C causes an anti-inflammatory response in your body and skin.  Preventing redness and sensitivity on the skin. 

    Vitamin C serums can be infused with other formulas to help boost this property.

  •  Agents like Salicylic Acid and Tea Tree Essential Oil are some of the ingredients used commonly to help fight the effects of acne, irritation, and redness. 

  • Speeds up healing :

    This is all thanks to the boost in collagen production that works to fasten the healing of wounds and the production of new skin cells for vibrant young-looking skin. 

  • Evens the skin tone:

    If you suffer from hyperpigmentation, skin blemishes from acne, sunburns, or an overall uneven skin tone then you might want to start using a Vitamin C serum.

    It helps to inhibit the enzyme tyrosinase, which catalyzes melanin production hence helps control pigmentation on the skin. 

    Using a vitamin C serum will definitely improve your skin’s overall complexion, brightening dull skin for a healthy, and more vibrant skin

    Vitamin C does this by brightening hyperpigmentation without interfering with normal skin pigmentation. 

  • Boosts Hydration:

    This is another benefit you stand to gain when using vitamin C. One of the main derivatives of this powerful antioxidant is Magnesium ascorbyl phosphate which has proven to have great hydrating effects on the skin. 

    This agent reduces transepidermal water loss and allows your skin to retain moisture for long periods. 

  • RetainYouthful skin:

    You’re guaranteed to retain youthful skin when using vitamin C. The regeneration of new skin cells helps your skin to always look young and revitalized. 

    It also aids in preventing aging signs like wrinkles and fine lines through the tightening and hydration of the skin.


Now that you know what to look for in a vitamin C serum, it’s benefits, and how to use it, ensure that you take your time to find the best product. 

If you are having trouble deciding on a product, you can check out the list of the best vitamin C serum’s reviewed at the beginning of this guide. This will help point you in the right direction.

One, more thing to note is that although vitamin C is naturally found in some plants and foods that we eat, it’s not advisable to apply pure vitamin C directly on the skin. 

While you might be tempted to do this, remember that Vitamin C or ascorbic acid is an acid and you need a measured concentration to add to the skin. In it’s purest form, the concentration of this acid is 100% and very harsh to the skin. 

That being said, you can use vitamin c powder to create your own homemade serum if you have to absolutely do it.
