You should first consult Skin Deep Database as so many popular face washes and cleansers have been found to be seriously skin (and in some cases health) harming. They can worsen or cause pimples and spots. The Database identifies which ones are safe and which ones are not.
Clinique, Cetaphil, Neutrogena and Aveeno suggested in other answers were identified as having harmful ingredients. Enter in the Database Search Box "Skin Care | Cleansing | Facial Cleanser " and scroll down the long list of products to find the truly safest non harming products.
