MD Skincare's Sunscreen Pads With Vitamin C, made by the New York uber derm Dennis Gross, look to be a great idea for girls on the go. The only problem is that one of the three sunscreens used is oxybenzone at the maximum concentration recommended of 6% (in Europe, a product that uses more than 0.5% must be labeled 'contains oxybenzone'). Oxybenzone (also called benzophenone-3) was linked to cancer in the late 1990s in a study published in the British medical Journal. Since then, the health implications of this sunscreen remain unclear. However, some studies have shown that oxybenzone can promote harmful free radicals in the skin cells. An Australian trial demonstrated oxybenzone is easily absorbed into the skin. French research also found incidences of contact allergies with oxybenzone.
