Product Details

Ideal for sensitive skin types or those new to vitamin C antioxidant serum, Serum 10 AOX+ utilizes 10% pure vitamin C (l-ascorbic acid) and 0.2% ferulic acid to help neutralize damaging free radicals that contribute to atmospheric skin aging – environmental damage and premature signs of aging caused by free radicals from UVA/UVB radiation. In addition to providing the benefits of vitamin C, this antioxidant serum also helps improve the appearance of fine lines and wrinkles.

  • Neutralizes damaging free radicals caused by environmental aggressors
  • Reduces the appearance of fine lines and wrinkles and helps restore healthy-looking skin
  • Paraben-, fragrance-, alcohol-, and dye-free
  • Ideal as an introductory antioxidant serum for all skin types, including sensitive

How To Use


In the morning after cleansing, apply 4-5 drops of this antioxidant serum to a dry face, neck, and chest before other skincare products. May also be used on backs of the hands. It is normal for vitamin C products to darken after opening due to air and light exposure. The formula will remain effective. Once opened, it is recommended to be used within 3 months of opening.

Complete your regimen with a SkinCeuticals sunscreen. When used together, SkinCeuticals antioxidants and broad spectrum sunscreens provide more comprehensive protection against visible aging caused by environmental aggressors.

  • Science & Proof

  • Science

    This lightweight antioxidant serum combines 0.2% ferulic acid with 10% pure vitamin C (l-ascorbic acid) for enhanced antioxidant performance.

    It is formulated under the Duke Antioxidant patent. Vitamin C is a highly-potent antioxidant that by its structure has difficultly being effectively absorbed by skin. The Duke Antioxidant patent outlines the formulation parameters required for effective delivery of vitamin C to skin: 1) pure l-ascorbic acid (vitamin C); 2) an acidic pH within the 2.0-3.5 pH range and; 3) a concentration between 10%-20%. SkinCeuticals is the only brand to formulate antioxidants according to these parameters.

Key Ingredients

  • 10% L-ascorbic acid
  • 0.2% ferulic acid

Lauded for its superior antioxidant benefits, this highly potent form of pure vitamin C helps neutralize free radicals and protect against oxidative stress while providing visible anti-aging benefits.

Rated 5 out of 5 by from Let me prface this by saying CE Ferulic lives up to the hype, but when you have sensitive and rosacea prone skin, it's just a bit too much. Enter Serum 10 AOX, which has the same ingredients but in lower concentrations. This is a holy grail Vitamin C product if you have sensitive skin and can't tolerate CE Ferulic.

Rated 2 out of 5 by from As soon as I opened it I saw it was oxidizes I purchased this product from one of the authorised retailers in Germany, Munchen. When I opened it I saw it was already oxidized, and I don’t even know if it’s safe to use it. At this price point you would expect more. It has a really sticky consistence. I cannot support it on my skin. I saw on my bottle it’s written only serum 10 but without AOX... i don’t even know the difference between them

Rated 5 out of 5 by from Great serum I have been using this for about a month and have noticed it helps with the fine facial lines to minimize them. It does have a bit of a smell to it and you do get used to it. Works great on my very sensitive skin!

Rated 5 out of 5 by from Serum 10 sensitive/reactive skin I would classify my skin as very sensitive & acne prone (with some Areas of dryness & oiliness). After Much trial and error with the various vitamins C products in the skinceuticals line, I have decided upon serum 10. I use a prescription tretinoin cream every night, so introducing any new skin care products into my regimen can be a challenge. This serum was the only one that did not burn or irritate my skin- in fact, it felt soothing! I currently use a gentle cleanser, serum 10, followed by b5 gel and a light moisturizer each morning and tretinoin followed by moisturizer at night. Love love love this and b5 gel by skinceuticals!

Rated 5 out of 5 by from I cannot say enough about this brand! You wouldn’t believe the changes in how your skin feel. This serum is great for someone who is just getting into using vitamin c, or someone who has very sensitive skin as it’s sooooo gentle! This was one of the first products I ever used and I was blown away after the first month. Being someone who has always struggled with my skin, I’m so happy to have found SkinCeuticles.

Rated 4 out of 5 by from Pleasantly Surprised I have very sensitive/reactive skin so I was a little worried about this product but all of my worrying was for nothing. I’ve had no issues and my skin seems to be brighter with more even tone after just a few weeks. The scent isn’t great, but I’d rather a natural scent compared to a bunch of fragrance/perfume additives.

Rated 4 out of 5 by from Great for Sensitive Skin I've been using for about a month. Serum 10 is good for sensitive skin, the CE Ferluic broke me out and had a stronger scent. This Serum 10 have a faint scent (to me it smells like coffee?) but it is not too strong. I have had no problems with new blemishes in using this product. I like that this can be an added layer of sun/environmental protection. I haven't yet seen results related to improving aging or fine lines.

Rated 5 out of 5 by from Smooth, younger looking skin My skin is very sensitive so I cannot tolerate the other retinol formula. This has been great. It does not dry out my skin or cause peeling.

Rated 5 out of 5 by from My new go-to! I just discovered this brand~ after a million years of using another high end brand. I wish I started earlier! This serum is wonderful as a starter for me... under my moisturizer. I’m already seeing a difference after just 2 weeks.

Rated 4 out of 5 by from This is a great alternative to the CE Ferulic if you have sensitive skin. It has a lower percentage of ascorbic acid (vitamin c) and minimal ferulic acid. While this didn’t irritate my skin like the CE Ferulic, I can’t say that it did a lot either. If you really want a vitamin c antioxidant serum and have sensitive skin, this is great. The price is also much better -more affordable, and the packaging is great.

Rated 5 out of 5 by from Soft glowing skin I started using this product about 2 months ago when I was given a sample to try. I have noticed the way that my skin feels softer and brighter. Sometimes I wonder if I'm just making things up in my head, but since starting a new facial regime, I have received so many compliments on my face!

Rated 5 out of 5 by from A Morning Must Have I have been using SkinCeuticals Serums for 3 years and I find them to be the best around. I am in mid-30s and spent all of my 20s in the sun. I find this serum to really help protect my skin AND make it look beautiful, youthful and glowing all day long - even into the evening hours. I apply it once in the morning all over my face and then add my moisturizer and face base... it is amazing and worth the money. Also, once bottle will last me 3 months so it is a great value. I get compliments on my skin frequently - believe me I have just recently (in the last 5 or 6 years) starting investing in these products and they reversed the damage done in my 20s for sure!

Rated 5 out of 5 by from Great results I have used SO many products trying to make my skin look better. I have used the SkinCeuticals daily moisturizer for about a year now and it is really great for my sensitive skin. I started using this serum at the recommendation of my esthetician, and love it. I moisturize in the morning after cleansing and use the serum at night after cleansing. I love the way it makes my face look and feel. I have acne prone skin and this product does not bother my skin in the slightest. I have had so many problems over the years with other products. Happy to have this product and I will continue to purchase this.

Rated 5 out of 5 by from Genie in a bottle This product is simply amazing. It works! I've been using it for 4 years now and the results now are as good as ever. When I first started using this produce, within a couple of weeks people noticed the glow in my face and I did too. Years later, people still raise a brow when I tell them my age. Highly recommend this product to everyone.

Rated 5 out of 5 by from Great product! I hope I don't jinks myself after writing this review because I tend to get jinks every time I think a product is the one. But wow...this product works wonders! This is my first time using skinceuticals. I just started using this product 1 wk ago and I must say I have never seen a product that works so well and fast in diminishing fine lines/wrinkles, smoothing skin texture, roughness, fading discolorations etc. I have tried all kinds of product in the past from the most expensive to the cheap over the counter and nothing has worked as good as skinceuticals. I was amazed in how fast this product actually works! I'm always in search of new and best products out there because every product I've come across and tried has disappoint and doesn't live up to what they claim. So I was a little disappointed in myself why I haven't found this product sooner until now! But I'm grateful I did find this product one night searching on youtube. My skinceutical regimen is using the serum 10 +AOX along w/ the Emollience cream and the Sheer physical UV sunscreen 50spf and it does wonders for my skin! No other product on the market come close to skinceutical and I'm proud to acknowledge that! I can't wait to try their other lines such as the Phloretin CF, Hydrating B5 gel, toners, scrubs, mask etc. I'm sure I'll be using these products as my holey grail now! Finally my skin can rest in peace, no more searching for that miracle cream! Thanks skinceuticals!!!!!!!!!!!!!!!!!!
