Review – SkinCeuticals Serum 10 AOX+



I have managed to obtain SkinCeuticals Serum 10 AOX+ sample in a generous size, which actually last me for more than a month. 

Product claims

Formulated with 10% L-ascorbic acid, this antioxidant treatment helps protect against damaging UVA/UVB rays, prevent premature signs of aging and stimulate collagen production. Serum 10 is lightweight, fast-absorbing and optimal for sensitive and acneic skin.

My experiment with the product

Before trying SkinCeuticals Serum 10 AOX+, I was a bit skeptical whether my skin will get allergy with 10% L-ascorbic acid. Although scientifically, L-ascorbic acid is claimed as a potent form of vitamin C but it is known to be very unstable. Having a sensitive skin, I have to be extremely cautious on any acidic ingredient. The highest I have tried so far is 5% and it was fine on my skin. In fact, many studies have shown that 10% is the correct and minimal concentration of vitamin C, to see proven results.

I have encountered some minor temporarily irritation with tingling sensation that last about 10 minutes or so during my first few rounds of applications. In fact, some dermatologists believe that these are the signs that the product is working. But occasionally, I do encounter some irritation which I get itchy on some small spots on the skin. I reckon it is due to my sensitive skin.

Different strengths to suit your need

SkinCeuticals Serum 10 AOX+, ideal for sensitive skin types or acne conditions, combines 10% L-ascorbic acid with ferulic acid to provide antioxidant and anti-aging benefits. 

So if you want to try something stronger, you may consider SkinCeuticals Serum 15 AOX+(15% L-ascorbic acid) and Serum 20 AOX+(20% L-ascorbic acid), both combine with ferulic acid.

Ingredients & Benefits

L-ascorbic acid, also known as vitamin C, is a powerful antioxidant that neutralizes free radicals, defends against environmental damage and helps prevent premature signs of aging. It reduces the appearance of the lines and wrinkles, provides photo-protection and stimulates collagen synthesis.

SkinCeuticals has discovered a way to get vitamin C into the skin when applying it on the surface is to combine it with ferulic acid. Ferulic acid, occurs naturally in plants and is a source of ultra-violet (UV) protection, increases the stability of vitamin C.


After a month of usage : SkinCeuticals Serum 10 AOX+ has helped to improve my skin texture and skin elasticity. Skin is firmer and healthier. I have also noticed the fine lines on the forehead have reduced significantly.

But there is no visible improvement on the pigmentation.


Will I buy it? …… Most likely!

    Hi Myo,

    If you skip toner, use this serum after cleansing and before moisturizer. It is definitely alright to use it with other product line.
