The Neutrogena Wave Power Cleanser does a good job of exfoliating my skin when I don't have a chemical peeling agent available, but there are some issues. My face at times can become extremely dry depending on my regiment so I use this device to remove the dead skin cells. I can only use this device for maybe a minute on my entire face every other day or it will cause a very bad skin irritation. I have tried using this device for longer periods of time to get rid of all the dead cells and ended up with a lot of painful bumps. This device also has a tendency of removing natural oils from my face, which has led to gritty skin over time, but it was reversible after I stopped using it. The Wave Power Cleanser has become mainly a back exfoliator for me. The skin on my body is less sensitive than my face so it allows me to spend a little more time exfoliating with this device. This device has greatly improved my complexion. This device over the course of 3 months helped to fade 10 year old back acne scars. The only downside to using the Neutrogena Wave Power Cleanser on a larger area is that the battery drains very quickly. Even though this device has helped me tremendously I wouldn't recommend this product because I received the same results with towelettes and baby wipes.
