What's in cosmetics?

Fragrances and preservatives are the main ingredients in cosmetics. Fragrances are the most common cause of skin problems. More than 5,000 different kinds are used in products. Products marked “fragrance-free” or “without perfume” means that no fragrances have been added to make the product smell good.
Preservatives in cosmetics are the second most common cause of skin problems. They prevent bacteria and fungus from growing in the product and protect products from damage caused by air or light. But preservatives can also cause the skin to become irritated and infected. Some examples of preservatives are:

• paraben
• imidazolidinyl urea
• Quaternium-15
• DMDM hydantoin
• phenoxyethanol
• formaldehyde
