COMPARISON: The best vitamin C serum

Vitamin C is an amazing skincare ingredient. Using it in your morning routine will help you achieve a brighter skin while reducing spots and fighting premature signs of aging. However, finding the right vitamin C serum isn’t easy, but this comparison (with products from NIOD, The Ordinary, La Roche-Posay…) is the solution you need.

Hi! You can finally read my vitamin C serums comparison! You know that vitamin C is one of my favorite ingredients in cosmetics, since it provides us with a huge dose of antioxidants and helps us to improve tone and texture, and to reduce blemishes, wrinkles and expression lines. However, it is not always easy to find the right product for our needs, especially considering that it is best to start using products with a lower concentration of ascorbic acid (as I explain in my guide on vitamin C, which you should read before starting incorporate this ingredient into your beauty routines).

Do you want to find out what is my favorite vitamin C serum and why? Keep reading!

Specifically, in this comparison I am going to talk about these products:

• The Ordinary Vitamin C Suspension 23% + HA Spheres 2%.
• NIOD Ethylated L-Ascorbic 30% Network (ELAN).
• La Roche-Posay Pure Vitamin C10.
• Skin Regimen 15.0 Vitamin C Booster.
• Jumiso All Day Brightening & Balancing Facial Serum.
• Kiehl’s Powerful Strength Line-Reducing Concentrate.

In addition, I will tell you about two other products that, although they do not contain vitamin C, help to improve the effectiveness of this, so they will be very good additions to all your routines when you use vitamin C. These products are:

• The Ordinary Resveratrol 3% + Ferulic Acid 3%.
• Klairs Freshly Juiced Vitamin E Mask.

1. THE ORDINARY VITAMIN C SUSPENSION 23% + HA SPHERES 2%.

This is undoubtedly one of my favorite vitamin C serums. If you want to know more about it, you can read its full review here. As its name indicates, this product has an ascorbic acid concentration of 23%, so I recommend it if your skin has already acquired a certain tolerance to vitamin C. Its texture is very light, creamy, with a slight sensation. gritty when applying the product that can be unpleasant at first (that’s why I usually recommend mixing it with a good hyaluronic acid serum like this one from The Ordinary).

Among the ingredients of this serum we find ascorbic acid, which is the purest form of vitamin C and that helps us to improve the tone and texture of the skin, in addition to reducing blemishes; squalane, which provides us with deep hydration, in addition to fatty acids; and hyaluronic acid, which helps us improve skin hydration and about which you can read more here https://imthemoisturizer.com/acido-hialuronico-beneficios-piel.

Regarding efficacy, this serum has given me very good results. Using it has greatly improved the texture of my skin and some small spots that I had have disappeared, making it a fantastic choice. However, remember that before starting to use such a powerful product, your skin must generate a certain tolerance, so I advise you to use another, milder product such as The Ordinary Ethylated Ascorbic Acid 15% Solution, which you can find on DECIEM (recommended).

2. NIOD ETHYLATED L-ASCORBIC 30% NETWORK (ELAN).

Those of you who follow me will know that NIOD is another of my reference brands. In previous posts I have told you about other brand serums such as CAIS 2 (an excellent solution to improve wrinkles and lines of expression) or the NAAP (a marvel in improving skin tone and texture).

In this case, they have developed a serum with a slightly oily texture and which incorporates 30% of vitamin C. Specifically, they have used a more stable form of vitamin C (ethyl ascorbic acid) than pure ascorbic acid. As you can see, the list of ingredients is very short, but not for that reason it is not very effective. In addition to ascorbic acid, they have also incorporated superoxide dismutase, a very powerful antioxidant that adds to the effects of vitamin C itself.

This serum is very comfortable to use, it is not uncomfortable despite the acidity of its concentration of vitamin C, so once your skin has a certain tolerance to this ingredient, I recommend it without a doubt. Your skin will love that you use this serum.

3. LA ROCHE-POSAY PURE VITAMIN C10.

A bit ago I shared the complete review of this serum from La Roche-Posay. As its name suggests, it contains a concentration of 10% of vitamin C, so it can be a good option when starting to incorporate this ingredient into our beauty routines.

It is a serum with a fantastic texture, it leaves the skin super soft. However, I think the brand could have dispensed with alcohol and perfume in the product’s formulation. After all, they are potentially irritating ingredients that can be replaced by others that are equally effective. On the other hand, the container is made of transparent glass (which facilitates the oxidation of a product that has a PAO of 2 months) and its dropper is not exactly comfortable.

I think if you are looking to start using vitamin C it is an acceptable option, although there are other, more inexpensive, products that will give you an equally effective result, such as The Ordinary Ethylated Ascorbic Acid 15% Solution, which you can find on DECIEM.

4. SKIN REGIMEN 15.0 VITAMIN C BOOSTER.

When they contacted me from Skin Regimen to try this serum (among other products from their range) I was very excited. In this case, we are dealing with a serum with 15% vitamin C, in this case in the form of pure ascorbic acid and sodium ascorbate (a derivative of vitamin C). Its intermediate concentration of ascorbic acid makes it a good transition product among others with a lower amount of vitamin C and other more powerful ones.

As for texture, in the first place it leaves a sticky sensation on the skin, although after a few seconds it becomes soft and very pleasant. Getting used to that transition is strange at first, but once you do it is a great feeling.

An aspect that I did not like about this product is its rapid expiration. Its PAO (Period After Opening, time that the product can be used once it is open) is only one month, so you must commit to using it daily if you do not want the product to lose its stability and, therefore, stop working as it should. Being a product that is not exactly cheap, I think that from the brand they should have opted for greater durability.

5. JUMISO ALL DAY BRIGHTENING & BALANCING FACIAL SERUM.

This is a somewhat particular product, since it is not a serum for the use of vitamin C. In addition to the ascorbic acid itself, this serum incorporates in its composition other ingredients rich in vitamins, as well as niacinamide (which helps us improve the skin texture and reduce redness), hyaluronic acid (which helps us improve skin hydration) and centella asiatica (with important soothing properties). However, its main component, of which it contains more than 86%, is sea buckthorn extract, which provides us with a large dose of antioxidants and vitamins A, B, C, D, E and K.

The main result that I have noticed when using this serum has been the improvement of the skin texture, for which I needed to use it for a couple of weeks. For its part, the texture of this serum is quite dense, although on the skin it is very light and comfortable to apply.

This is another good serum to start incorporating vitamin C into your beauty routines, since it provides us with antioxidants and helps us to improve the texture and tone while giving us the soothing properties of centella asiatica.

6. KIEHL’S POWERFUL STRENGTH LINE-REDUCING CONCENTRATE.

You may remember this serum from my review of the Vitamin C Suspension 23% + HA Spheres 2% from The Ordinary, as both of them have a very similar texture. However, I like the composition of this Kiehl’s serum less than that of The Ordinary, since it incorporates citrus essential oils, potentially very irritating ingredients for the skin and that are totally unnecessary in such a product.

In this case, Kiehl’s have developed a product with 12.5% ​​ascorbic acid and 2% ascorbyl glucoside, a derivative of vitamin C. To be a product with a relatively low concentration of ascorbic acid, I found it excessively irritating It gave me a first itchy sensation that needed a minute for it to subside.

Taking into account the price and composition of this product, I would opt for one of the others that I mentioned above before this one.

BONUS: The Ordinary Resveratrol 3% + Ferulic Acid 3%.

As I mentioned before, this product does not contain ascorbic acid (or any of its derivatives) in its composition, but when used in combination with your favorite vitamin C serum, it will help boost its results, creating a powerful network of antioxidants to help you. to prevent the effects of free radicals and, thus, progressively reduce wrinkles and expression lines.

This serum from The Ordinary has an oily texture that leaves a very comfortable feeling on the skin, without being heavy at all. Whenever I use a vitamin C serum I try to use it and I recognize that the difference is noticeable.

You can get the serum The Ordinary Resveratrol 3% + Ferulic Acid 3% on DECIEM (recommended) and on SkinStore.

BONUS: Klairs Freshly Juiced Vitamin E Mask.

You probably remember this Klairs mask from the full review I shared of it (https://imthemoisturizer.com/review-klairs-freshly-juiced-vitamin-e-mask-2). It is a very particular product, since it can be used as a mask or as a moisturizer at night.

It is a very, very hydrating product with a magnificent texture. In addition, among its ingredients it includes niacinamide (which helps us to improve skin texture and redness), hyaluronic acid (to improve skin hydration) and ceramides (which also improve hydration and help us to better protect the barrier). of the skin).

Without a doubt, I recommend this product to finish all the night routines in which you use vitamin C, you will notice the difference.
