In addition to antioxidant benefits, this facial serum minimizes the appearance of fine lines and wrinkles.

Key Ingredients:

  • 20% L-Ascorbic Acid: this highly potent form of pure vitamin C helps neutralize free radicals and protect against oxidative stress while providing visible anti-aging benefits
  • 0.2% Ferulic Acid: a plant-based antioxidant, ferulic acid neutralizes free radicals and enhances the antioxidant benefits and stability of vitamins C

  • Helps prevent the appearance of accelerated aging

Tip: 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.

Once in the morning after cleansing, apply four to five drops to a dry face, neck and chest. Follow with SkinCeuticals Hydrating B5 Gel and a SkinCeuticals moisturizer and sunblock.

Great C-serum

This is a little cheaper than Ferulic and sometimes I buy it instead of the more expensive ones. Slinceuticals never disappoinits.

Brightening Power

I worked my way up to the Serum 20 AOX. My skin is brighter than before, noted by myself and others. My acne scaring is also less noticeable. I’ve been using this product for over a year with great results.

Great for when the sun is super strong!

Worked great during the summer time when the sun is extra strong! Used it under my sunscreen for extra production. A bit too strong for the winter when my skin is more dry. It stings a bit so I stopped using it. I'll pick it back up again for the summer. Smells a bit weird but nothing too bothersome.

My Go-To Serum

I started off using the AOX 10 and after 2 bottles switched to the stronger 20. My skin has been loving it! I highly recommend!

Love Skinceuticals!

I switch back and forth between this and CE Ferulic. I'll try anything once, but always return to Skinceuticals.

Upgrading from Serum 10!

I recently decided I would move from Serum 10 up to Serum 20. I have sensitive and acne prone skin, so I'm always cautious about adding new products to my routine. It's been about 2-3 weeks and the Serum 20 has been gentle on my skin and overall I'm very happy with the upgrade. I use the Serum 20 in the morning and then the Blemish + Age defense serum and Triple Lipid Restore at night and they have definitely improved the overall radiance and texture of my skin. Happy customer here!

Perfect for oily/combo skin!

I'm glad I went with this particular vita C serum as it seems to be the perfect fit for my combo skin, which can be quite oily in the summer. It absorbs quickly and plays well with all of my other skin care. A week into using it, I can see that it will stay in my routine forever. Worth the money!
