The stimulation of the superficial fascia with the BLACKROLL® NEEDLEROLLER has many effects. The tingling, blood circulation-promoting effect is immediately noticeable; the pain sensitivity is reduced significantly after a short application. In combination with the treatment of deeper tissue layers, the BLACKROLL® NEEDLEROLLER can regulate collagen and elastin production. The pressure of the BLACKROLL® NEEDLEROLLER can be dosed very well. Roll on the skin back and forth and thus stimulate the free nerve endings in the skin. The NEEDLEROLLER is particularly suitable for stimulating the reflex and acupuncture zones.
