According to the study, and a forum I'm checking out, we are supposed to do one vigorous roll and wait 4-6 weeks or do a very light roll everyday. The light roll will improve better penetration of products. The deep role reaches the dermis layer to stimulate inflammation and healing. This stimulates the body to produce collagen to heal the area (tricking the body into thinking the wound is more serius than it is). The healing requires 4-6 weeks. That's why it is recommended that we don't roll vigorously more than once during this period, because the skin won't heal properly and can cause the situation t worsen. At least that's what I learned so far. If I like this method, I will get another dermaroller with smaller needles for product penetration.
