Oh, I love my Wave. It's probably the best thing I've ever done for my complexion.
To use a Wave, first put on the pad on the Wave, wet it, turn on the Wave, and start moving it over your face. Make sure to have a washcloth near by before doing this. I know it may seem obvious, but I've forgotten to do so more than one time.
Immediatly after, my face is a little bit red, but this goes away after a few minutes. Afterwards, my face is soft and smooth. I use my Wave first thing in the morning, because often I need a little waking up, and this does the trick everytime. This does help with my acne, I've seen most of it vanish after I started using it. However, in many cases washing your face is always a good way to prevent acne. :)
When I use my Wave, I usually put a headband on first, because if I don't I'll get the soap in my hair, and that's annoying.
After getting my Wave, I noticed my face felt softer, I felt better, my complexion improved, and I wake up to a brighter morning. I would definetly recommend it. :)
