Moisturizer Ingredients

With so many moisturizers on the market promising different results, it's important to consider the ingredients. Humectants like glycerin and urea help by absorbing water from the air and holding moisture in the skin. Emollients like mineral oil, lanolin and petrolatum fill spaces between skin cells, replacing lipids and smoothing and lubricating rough skin. Occlusives -- like petroleum jelly and cocoa butter -- are oily substances that form a film on the top of skin, sealing in cracks and preventing moisture from escaping. Some additives like fragrances could cause your skin irritation, so check any lotion's ingredient label before using.
