I know there is a huge Lumea thread but I don't have a Lumea - I have a Braun silk-expert pro 5, one of the most recent models which came out this year.
I've been using it religiously every week for three weeks (this weekend will be no. 4) and I'm a little worried that so far I've seen no difference.
I've found the occasional hair which falls out, and I think hair is growing back more slowly after treatment, although the latter is more likely to be wishful thinking and obsessive checking on my part!
I have very pale skin and dark hair, so the perfect candidate. I'm treating my lower legs, bikini line, and underarms.
Am I being too impatient? I am a worrier by nature 
and it was a lot of money to spend.
