Best Vitamin C Serum – Detailed Reviews and Where To Buy

If you’re a beauty and skin care enthusiast, you have probably heard of vitamin C serums. Vitamin C is all the rage right now since it claims to have the ability to prevent and even reverse aging. These are just among the many other benefits of vitamin C serum for the face, and it has quickly gained superstar status over the past few years. This tidbit isn’t surprising at all - even before it garnered attention in the skin care world, everyone had already known that it is a powerful antioxidant.So in this article You will get to know about the best vitamin c serum you can go for.

What To Look For In A Vitamin C Serum

There are many forms of Vitamin C for the skin. You’ve got Ascorbyl Palmitate, Magnesium Ascorbyl Phosphate (MAP), and L-Ascorbic Acid (LAA). Among these most common types, the ingredient that you want to see in your serum is L-Ascorbic Acid.

This is because this absorbs better than others, therefore offering you better results. However, LAA can be finicky. It’s the most difficult to use because of its habit of oxidation (a chemical reaction from being exposed to oxygen), but is a powerful ingredient when formulated properly, especially when mixed together with other skin beneficial ingredients like vitamin E.

A well formulated vitamin C serum should be clear and pale yellow in color. If your serum is orange or a dark yellow, it means that it has already oxidized and is no longer safe for your skin.

It normally oxidize after a certain amount of time so you better use it up before it becomes practically useless! To delay its oxidation and prolong its usage, the serums ideally come in dark or opaque glass bottles to prevent exposure to air and sunlight, which promotes the process of darkening. Some users also store their bottle in the fridge, and that’s been proven to be helpful as well.

Although a little hard to manage, proper and regular use of vitamin C on your skin can do wonders. Aside from the benefits we’ve already mentioned, it also helps double up the sun protection that your daily sunscreen gives you.

Best Vitamin C Serum For Face - Reviews and Ratings

Here are our top picks that you may want to look into.

1. Skinceuticals C E Ferulic

The first vitamin C serum that we’re going to review is already winning in the ingredients department, considering its active ingredients are L-Ascorbic Acid, Alpha Tocopherol (vitamin E), and Ferulic acid. If you have no idea what Ferulic acid is, it’s another antioxidant naturally found in seeds of apples and oranges, and fights off free-radical damage that leads to visible aging of the skin.

It’s housed in a glass bottle and comes with a dropper so it’s easy to dispense. The product itself is a clear, pale yellow liquid that emits a slight odor because of its natural ingredients, but that fades pretty quickly once spread and massaged all over the face. Good news to those with sensitive noses. However, it leaves a slight sticky feel on your face which won’t be a problem if you apply a moisturizer or sunscreen afterward.

This serum is quite popular and is a favorite of many skin care enthusiasts and it’s not hard to see why. It has even won Allure Magazine’s Best of Beauty Award three times! The ingredients list is a winner, like we said, as it’s a combination of three of the most powerful antioxidants we know today. It also follows the packaging standard. It’s been proven to help prevent and smooth out wrinkles, fade dark spots and acne marks, and protect your skin from sun damage. Although it’s a little pricey but it’s totally worth it.

This best antioxidant serum by Skinceuticals is available on their website,, and on Amazon.

2. Kleem Organics Anti-Aging Vitamin C Serum for Face with Ferulic and Hyaluronic Acid

Looking at its ingredients list, Kleem Organics’ contribution to the vast range of options seems to have so much potential as well. Although the company doesn’t specify which form of vitamin C they are using in this formulation, the serum contains vitamin E and Ferulic acid, plus Hyaluronic acid. We’ve already gone over what Ferulic acid is, but here is a new term. For those who do not know, Hyaluronic acid is a molecule naturally occurring in the human body. It secures moisture in our skin and hair, giving the appearance of smooth and plump skin. Sounds good? Aside from these four powerhouses, it also boasts of jojoba oil, witch hazel, and Aloe Vera. This self-proclaimed best antioxidant serum is an organic vitamin C serum, and is proudly paraben-free and cruelty-free.

The packaging is also quite impressive - it is contained in a modern, air-tight bottle and is dispensed by a pump to completely avoid exposure from air and sunlight, therefore preventing oxidation until you use it all up!

Unlike Skinceuticals’ serum, Kleem Organics’ vitamin C serum has a natural citrusy scent that will please those of you who like fragrant skin care products, or just sensitive to weird odors. It also doesn’t leave any sticky residue on the skin.

This is reportedly the best vitamin C serum with hyaluronic acid, and is a favorite in the world of skin care addicts. Users say that it drastically reduced their acne, faded leftover hyperpigmentations, and significantly improved their skin’s hydration.

4. Cosmetic Skin Solutions Vitamin C + E Serum

This serum contains 15% L-Ascorbic Acid, 1% Vitamin E, and 0.5% Ferulic acid - the three antioxidants we all love and think we deserve. Just like any other vitamin C product, it promises to protect skin from free-radical and sun damage, improve the skin’s elasticity, and even out the skin tone. It’s oil-free, paraben-free, and cruelty-free. Sadly, it’s not free. That is not surprising since it claims to be of high quality and is the best vitamin C serum for acne-prone skin.

Like most serums, this comes in a standard dark-colored glass with a dropper to dispense the product. Here is our metaphorical seal of approval!

Many users have compared this serum to the Skinceuticals one, saying it is identical and works just as well for a fraction of the price. One reviewer even said that this easier to apply as it absorbs faster and better. Users noted that here have been a significant decrease in their fine lines and wrinkles, sun spots, and post-acne marks. However, there clearly have been mixed reviews, as some complained about it not absorbing, breaking them out, and/or making them look greasy.

Seeing the promising ingredients and its lower price point than Skinceuticals C E Ferulic Serum (which is supposed to be almost the same), it might be worth the gamble. Cosmetic Skin Solutions Vitamin C + E Serum can be purchased from

5. Vitamin C Serum 22 by Serumtologie

This serum boasts of its 22% vitamin C content. This ingredient is actually Sodium Ascorbyl Phosphate (SAP), an alternative to L-Ascorbic Acid, and is a fairly new formulation. Studies show that it has the potential to perform on a par with LAA, but that is yet to be proven. However, the rest of the active ingredients in this serum give us high hopes. Aside from vitamin C, it contains vitamin E, Ferulic acid, and Hyaluronic acid. It also has Aloe Vera (pretty high up on the list, so you can go use this on sunburns), witch hazel (good for acne ridden skin), and jojoba oil (is the closest to our skin’s natural sebum, so it balances the skin’s oil production). The formula is free of parabens, phthalates, artificial coloring, and fragrance. It’s also 100% vegan-friendly as it is cruelty-free!

The bottle is a dark-ish blue glass packaging and comes with a dropper. This makes for easy dispensing of a few drops to the palm of your hand. Typically, it would take 4-5 drops to cover an entire face.

This serum also shows to be a fan favorite as it does what it says it does. It helps moisturize the skin, reduces fine lines and wrinkles, fades dark spots, and evens out the skin tone. As with any other serum, you will benefit more with the use of daily sunscreen to protect you from the darkening and aging rays of the sun.

  • Is it good for wrinkles?

Wrinkles and other symptoms of skin aging are actually signs of skin damage from the sun’s harmful UV rays. UVA rays break down the naturally occurring collagen in our skin, making it lose its elasticity which leads to everyone’s greatest fear - wrinkles.
