The stimulation of the superficial fascia with the BLACKROLL® NEEDLEROLLER has many effects. Firstly by stimulating nerve endings on the skin and superficial fascia, the pain sensitivity is reduced by breaking pain feedback loops. 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 regulated very accurately. It is the perfect tool for preparing for a foam rolling session!
