I didn't use it specifically as a moisturizer, I used it to treat my acne, and I didn't want to use something that dries the skin, like products containing benzoyl peroxide, or salycylic acid. Acnessential contains neither of these ingredients. Its main active ingredient is niacinamide, which not only treats acne, but also acts as a moisturizer. I have to say that not only did it completely clear the acne on my face and back after a few weeks, it left my skin with a real healthy looking glow. I highly recommend Acnessential for getting rid of acne and zits, especially if you're looking for something that hydrates the skin as well.
