I really didn't know if I was doing a stupid thing spending this much money, but approaching my 40th birthday made me want to invest in a product I hoped could help with the (still slow luckily) changes in my skin.
I felt the benefits of the ZIIP from the first treatment, and with regular use I started seeing them too.
I have been very enthusiastic and used it 6 days a week (the maximum use suggested).
When I first started using it I felt a feeling of 'freshness' from within the skin, as if I had splashed cold water from the inside of my face, then I started noticing a glowing skin tone and better texture too.
I have a lot of darkness under my eyes and that is slowly improving, but the swelling I get from sleeping I think might take will take longer to improve (I remember seeing a review that said it took 6 months for the under eye bags to improve).
Unfortunately I noticed a crack between the two probes that kept getting bigger until some of the plastic started peeling, so that when I used the device the bit that stuck out lightly scratched my skin.
However Currentbody.com has promptly answered my email providing instructions on how to send the ZIIP back for a replacement.
I just sent it back and hopefully will receive my replacement soon.
I will post another review upon receiving my new ZIIP.
