How does Multitrepannic Collagen Actuation work?

MCA works by creating a minor trauma to the skin. The epidermis is stimulated to undertake its own natural rejuvenation, re-pigmentation, scar relaxation or whatever results the practitioner is striving for. As the needle enters the skin, the dermis starts the inflammation and swelling phase. Fibroblasts move into the area and start producing collagen and elastin to help with wound healing. If there is any visible condition that needs healing (swelling, bruising, etc), this will take about 3-7 days. In the process, the existing collagen levels are raised and good results are achieved. It is stated that the deeper the penetration in to the dermis, the better collagen and elastin deposition. Tissue remodeling is also a phase of MCA healing.
