I really like this microdermabrasion home treatment. There were some reviews I read saying about grazes and the disc not reaching the skin...I can honestly say if you read the instructions - which incidentally are supplied with the device under a flap on the top in loads of detail or online with videos, which I found super helpful and a must, you just can’t go wrong! It really is a must to pass only once and support the skin if it is lax to avoid over exfoliating and please do check you have the right grade disc and cover not the ones for the body all mixed up or they won’t reach the skin. You wouldn’t want them on your face anyway. My skin is now brighter and fresher looking, so much so that people in Zoom have noticed. It’s great the refills are easy to buy too. Brilliant price of kit!
