The dermal roller is the best and most effective device for deep transdermal enhancement of active substances through the epidermal barrier(stratum corneum)

The uppermost skin-layer, the epidermis , is a brick-like structure of scales. The mico-needles only push them aside, forming tiny mico-pores. While the dermal roller over the skin the previous applied substance (cosmetic only) is transported the deeper skin layers. Parallel to this action the stratum corneum acts like a longterm depot to retain the active substance
