I saw this and my hair stand. Who will use this kind of thing? It is needled roller bowed over faces. What does it use for? It is for punctures the skin with a needled roller, ironically created to repair the skin! This Microneedle Theraphy system works on philosophy that “injuring” the skin will induce the release of growth factors to stimulate the production of more collagen and elastin, thus reducing wrinkles and improving skin texture. Side effects include bleeding,bruising and redness for few days. I wonder why people wanna torture themselves with this. I don’t think I will use this. I rather drink the collagen drink.
