Principally there is none, both models (medical and home care) only differ in needle size. While the medical Dermarollers have longer needles from 0.5 to 1.5 mm to induce collagen in deeper skin layers, the needles of the Home Care Dermaroller are very short, not more than 0.18 to 0.20 mm. The Home Care Dermaroller serves the following purposes:

a)    To enhance active substance through the skin barrier (stratum corneum)
b)    To improve and support results after and in between CITs by:
c)    Stimulating epidermal cells for proliferation that results in a faster renewal cycle of the epidermis and thickens the epidermal cell layers.

The Home Care Dermaroller does NOT induce new collagen layers, and it is NOT suitable for scar treatment, but it helps to maintain beautiful skin.
