It is necessary to check the ingredients listed on all of your skin care products since acne causing ingredients are not limited to these classes of cosmetics. Comedogenic ingredients can even be found in suntan lotions and creams. Moisturizers can also be a source of acne producing substances. In order to make these moisturizing products smooth on the skin easily, they are often manufactured with ingredients such as acetylated lanolin, searic acid, and cetyl alcohol. All of these ingredients are considered to be comedogenic.
Most dermatologists recommend moisturizers that have a base of petrolatum or mineral oil.
