About Cerave, some are concerned that the product may be causing breakouts. A recent study published in the European Journal of Dermatology found that cerave sa cleansers can cause inflammation and acne in people with sensitive skin. The study participants were given either a placebo or a cerave SA cleanser with an active ingredient known to cause inflammation. Those who used the cerave SA cleanser had an increased chance of developing acne than those who used the placebo. While this study is small and does not necessarily prove that cerave SA cleansers are responsible for breakouts, it indicates that people with sensitive skin should avoid using them.
