What Does Stable Vitamin C Mean?

Vitamin C is the trifecta of skincare, it evens out pigmentation, reduces fine lines and wrinkles, and is a powerful antioxidant. The only downside is it can be very unstable.

When vitamin c is dissolved in water solutions, it becomes sensitive to light and oxygen. It will immediately start to break down, rapidly lose its efficiency, turn brown in color, and may even start to have a foul smell.

Now this is specifically referring to l’asorbic acid, which is pure vitamin C. There are other derivatives of vitamin c that are more stable, however, they are not as powerful and won’t give you the results you’re after.

The BeautyStat Solution

With over 5 years of research and testing, BeautyStat found the solution!

With 3 patents on our encapsulated pure vitamin C (l’asorbic acid) formulas, our Universal C Skin Refiner and Universal C Eye Perfector are stable from the first pump to the last – no matter how long the product has been sitting on your counter or how much light and air it has been exposed to. This means you will see visible results faster than any other product on the market!


We did a comparison stability test against leading competitors in Vitamin C products and ours remains pure and active while the competitor formulas oxidize, turning orange or brown.
