I started to use my RoseSkin machine about 6 weeks ago.
Even if it's very slow, I've noticed that my hairs started to grow thinner and fewer.
I purchased this product to help with ingrowing hairs, and I notice a slight improvement too.
It's a slow process so far, but it doesn't hurt (from level 5, you do feel like a pinch when the light flashes).
The only thing that is a bit annoying is that the machine does a lot of noise and heats pretty fast.
