A friend of mine bought one of these she was trying to not have any wrinkles even START and I think that's a good idea, but it didn't do anything for her and she sent it back it was a big waste of her time. And hope.
Ive had a derma wand for a few years now, I don't use it often but I used to & I did find that it worked ok for me. I was 33 when I bought it so maybe it depends on how old or wrinkled that your skin is as to whether it works well for you or not.
I read a review about it and there are some positive results that people are having. I would suggest that you read this review on Derma Wand before purchasing one. If it works, I wouldn't mind getting one too. Let me know how it goes.
