Vitamin C Serum Side Effects

It’s no secret that vitamin C is important to a healthy diet. It has plenty of benefits and generally, we think of vitamin C as something present in healthy fruits and vegetables like citrus fruits (oranges, lemon, kiwi), strawberries, tomatoes, broccoli, etc.

In the modern world though, it is easier than ever to get essential vitamins and minerals in other ways. We can shop online or go to just about any store and purchase a plethora of vitamin C products, including serums.

Vitamin C serum has plenty of benefits, and we’ll get into those later, but as with most products, you might be wondering, what are the Vitamin C serum side effects?

This guide will examine Vitamin C serum, what it is, what its side effects are, and how it can be beneficial for its users. So, settle in as we dive into the world of Vitamin C serum.

What Is Vitamin C Serum?

Have you ever had someone tell you that if you feel the common cold coming on, or if you’re feeling a little under the weather, you should take some Vitamin C?

That’s because Vitamin C is an incredibly powerful antioxidant that the body uses in fighting off infections. It is also prevalent in the manufacturing of collagen, which is a protein that helps make connective tissue found in the skin and other parts of the body.

In a similar manner, Vitamin C is a wonderful active ingredient in topical cosmetic products and serums due to its incredible benefits.

Vitamin C serum is a type of skincare product that has the consistency of a liquid or a gel and is generally thinner than creams or lotions. It has many redeeming qualities in that it does wonders for aging, helps target wrinkles and fine lines, fights off free radicals, and can even help with acne and hyperpigmentation.

While you’re likely getting Vitamin C from your diet, there’s no guarantee how much of it is being absorbed by the skin. As such, you would apply a Vitamin C serum directly to your skin, similar to a sunscreen or face cream. This application allows you to absorb more of it in your body, directly targeting the skin. 

Many places sell Vitamin C serums. You can find it in beauty stores, drug stores, online; really anywhere you’d otherwise purchase skin-care products. 

Because of the benefits and accessibility of the product, many consumers will incorporate Vitamin C serum into their everyday beauty routine in order to get the most of its healing properties.

But what are the side effects and is there any truth to the beneficial claims?

Are There Any Vitamin C Serum Side Effects?

So are there any potential side effects you should be aware of before using a topical Vitamin C serum?

While in rare cases some may experience minimal side effects, Vitamin C serum is one of the safer ingredients out there. Most users will not experience any side effects at all.

Side Effects

Those that do experience side effects might notice redness, skin irritation, itchiness, and a slight burning sensation. 

Rare Side Effects

In extremely rare cases, people have noticed their skin changing slightly yellow and becoming irritated, but this is infrequent, and very few people have reported this symptom. 

Those with sensitive skin are the ones most likely to have any reaction at all, but again, Vitamin C is typically a very well-received ingredient with little to no side effects experienced. When in doubt, perform a patch test before diving into full application.

How To Avoid Negative Side Effects When Using Vitamin C Serum

It’s important to be aware of the other ingredients included in the Vitamin C serum you’re considering. Different formulations of Vitamin C and different mixtures of products can have varied effects, so focus on serums where Vitamin C is the primary active ingredient and has a strength of 20% or less.

Do Other Products Make The Side Effects Worse?

Be mindful of using a Vitamin C serum in conjunction with a retinol product. The combination of these two can cause irritation, so it’s best to alternate their use (i.e., use the Vitamin C serum in the morning and the retinol product at night).

Additionally, as with most products, you need to be extra careful if you’re applying this serum near your eyes. If you get any of it into your eyes, you’ll want to wash it out with clean, cold water immediately. 

The Science Behind The Claims 

There are many forms of Vitamin C and there are plenty of ways to get it. As we said, fruits and vegetables like oranges, pineapples, brussel sprouts, and broccoli all provide a good source of Vitamin C. 

Vitamin C is important for our normal bodily growth and development. It also aids in helping to fight off illnesses like the common cold, repairing damaged bodily tissues, and acting as a defense mechanism against free radicals through its antioxidant properties.

Our bodies and skin have a natural amount of Vitamin C, and while we produce small amounts, it’s not always enough to reap the benefits we desire. Moreover, simply turning to these aforementioned fruits and vegetables for assistance won’t entirely solve your skincare needs.

Scientists suggest that we don’t absorb enough Vitamin C because our skin’s epidermis does not have enough blood vessels to transport it to our skin cells. This is where a topical product like a Vitamin C serum can really come in handy.

According to dermatologists, a topical Vitamin C serum can help in a number of ways, including reducing the visibility of fine lines and wrinkles and improving the overall appearance of your skin.

It’s also great for brightening the skin and reducing redness and dark spots (hyperpigmentation) by limiting the amount of pigment in the skin. Similarly, it can help with acne because of its anti-inflammatory properties. 

Lastly, Vitamin C serum can be a useful protector of UV rays when used in conjunction with sunscreens and other topical products including the ingredients Vitamin E and ferulic acid. These combos can help reduce the redness from sunburn and protect against long-term skin damage and sunspots.

Who Is Vitamin C Serum Best For?

As we’ve noted, implementing a Vitamin C serum into your daily regimen can have a number of positive benefits. Vitamin C serum can help fight hyperpigmentation, wrinkles, sagging of the skin, dryness, redness, etc.

So for those experiencing any of these symptoms, it may be a good idea to add a Vitamin C serum to your skin-care routine.

It may also be smart to start using it even if you’re not immediately experiencing these symptoms. The best way to prevent aging, fine lines, and wrinkles, is to be proactive and target them before they start appearing.

Overall, Vitamin C serums can be used by pretty much any adult as they are well-tested and very safe. As we mentioned before, those with sensitive skin should be careful with any topical products, consulting their dermatologists or at least performing a patch test before full application.

How Do You Choose The Right Serum?

Choosing the right serum is essential when it comes to your skincare. Fortunately, there are plenty of Vitamin C serums on the market, and they’re easily sourced and even easier to buy. 

As we noted before, the Vitamin C concentration in the serum is important. Look for products that contain at least 10% concentration but not more than 20%. This is the most scientifically tested and trusted Vitamin C concentration range for getting the best results. 

The higher the concentration, the more potent the serum becomes, so be sure to implement it gradually when first starting out.

You can also look for Vitamin C serums that contain ferulic acid and Vitamin E. These ingredients work better together to create a more powerful and stabilized antioxidant.

How Do You Use Vitamin C Serum?

The best way to use this serum and reap all the benefits is to start by testing it out on a small area of skin, like your arm, to ensure you have no irritation or allergic reaction.

Assuming no reaction, you’ll want to first wash your hands and face thoroughly. Once dried, read the instructions on the label and apply a few drops directly on your face and neck and gently rub into the skin, ensuring you keep the serum out of your eyes. Based on your skin-care routine, you can follow it up with a moisturizer.

Because of its UV protection properties, it’s best to use a Vitamin C serum in the morning before applying sunscreen. 

It can also be helpful to introduce this serum gradually, applying first every other day, and then when comfortable and tolerable, begin applying once daily in the mornings.

It can take up to 2-3 months before seeing improvements, but with consistent application, the results will be worthwhile.

Also, make sure to store in a medicine cabinet or somewhere relatively cool and dark. Avoid storing in the heat and presence of light as Vitamin C can break down and be rendered useless.

Final Thoughts

Vitamin C serum is well-tested and overall, the large majority of users will not experience any side effects. Those with sensitive skin should test out the serum before working it into their daily routine so as to avoid allergic reaction and irritation.

Overall, using a Vitamin C serum consistently for at least 2-3 months can be a safe and effective way to combat aging, reduce redness, maintain moisture, and protect against free radicals and UV rays.
