Is “clean” or “dermatologist-tested” better for sensitive skin?

Skin care ingredients derived from natural sources such as plants or minerals are not guaranteed to be safer or better than ingredients made synthetically in a lab or factory. “Some naturally derived essential oils can be irritating to skin, causing contact dermatitis or other allergic reactions for some people,” Dr. Schlessinger says. “And poison ivy is natural, but clearly can make the person who contacts it miserable. This is a prime examples of the fact that ingredients from a natural source are not always better for everyone.”
