I have to say this little guy works better than any microdermabrasion mask I have tried.It's even fun to use. It did not hurt, but tingled and a little 'pokey' and it rolled smoothly.Instructions are clear and it said to sanitize with alcohol prior to first use (which I was planning to do, but not sure how & it said to rinse it for a min, then soak head in alcohol for 10 min).Wash face, use this 4 times in each direction, Then I followed up with vitamin E almond oil. It says don't use on eyes or nose. Prior to bedtime I used it mildly on my face (including eyebrows), neck, upper chest, gently on elbows & back of hands. I am 55 years old, Caucasian and my face had a pinkish glow the next morning. It says you may experience redness and skin peeling over the next 4 to 7 days, so plan accordingly. I recommend you don't push hard until you've used it a few times and know how your skin will react. I just laid it on my skin and didn't apply any pressure where my skin was soft, just rolled, and mild to gentle pressure where my skin was tougher or had lines.
