9 Sneaky Ingredients to Watch Out for in Skin Care Products

This might sound like something you don't have to worry about, but formaldehyde (and formaldehyde-releasing agents) are actually still found in skin care products and cosmetics.

Dr. King says, "These are a common cause of contact dermatitis and irritation of the skin. Formaldehyde is also a known carcinogen. Specifically, quaternium-15, DMDM-hydantoin, imidazolidinyl urea, and diazolidinyl urea are all formaldehyde releasers."

These ingredients are typically incorporated to kill microorganisms, but there are alternatives that do work. Check the ingredient list for these biggies and avoid them.
