It's extremely mild and a great way of cleansing your face. However, for acne, it's more geared toward people who are on topically applied acne medications (e.g. retinoids, spot treatments). This is so you can gently clean your face before applying the medication. It's a very basic cleanser just like Cetaphil. When used alone, it won't help prevent acne, but it's certainly a trust-worthy product when it comes to no irritation! Great for people with sunburn, eczema, etc.
