Avoid Vitamin C Products That Sting When Applied To The Skin

Skin Care Tip of the Day: Most Vitamin C products out on the market use the acid forms of the Vitamin (like Ascorbic Acid). These are in fact, acids, which is why you can feel a stinging sensation on the skin. The new research on skin aging indicates that daily use of skin irritating acids actually encourage free radical formation, which counteracts the reason why you’re using Vitamin C in the first place! Plus, the problem with these acid types of Vitamin C is that they are highly unstable and break down every time you open the bottle and oxygen gets to the product. If your Vitamin C serum starts to turn brown half way through the bottle, that’s a sign that it is oxidizing and is losing its effectiveness. (Think of an apple that turns brown 20 minutes after taking a bite.)

At Renée Rouleau, we use Magnesium Ascorbyl Phosphate, which is believed to be one of the most beneficial types of Vitamin C because it doesn’t cause skin irritation and won’t lose its ability to fight free radicals. So if you’re someone that has tried a Vitamin C serum before and had to stop using it because it was irritating your sensitive skin, then our Vitamin C&E Treatment is a must!

  1. I have a question.. I see this post was written in 2009 so I am wondering if this advice has changed at all given new research available? I have read to stay away from synthetic vitamin c because my skin cannot absorb it. http://www.annmariegianni.com/synthetic-vitamin-c-versus-natural-does-it-make-a-difference/

    • It is not true that synthetic vitamin C cannot be absorbed. If an advanced delivery system (liposome) is used it most certainly can deeply absorb within the skin and give powerful antioxidant protection.
