Skin Care Tip: Keeping Vitamin C serum fresher

submitted by Kate, Washington, DC

I think we all agree on the efficacy of Vitamin C serums. Although most of the producers of the serums say that deepening color doesn't mean the serum is no longer effective, I just prefer the serum to look as it did when I first purchased it. Most companies package their serums in amber colored bottles and a few have replaced the traditional eyedropper with a pump. Nevertheless, after a month, as oxidation set in, the color of my serum deepened. Based on a tip from my dermatologist, I now wrap my bottle of Vitamin C serum in plain old aluminum foil. It keeps the serum clear for months, so it must slow down the oxidation and I'm confident that now I'm receiving more benefits!
