This topic is intended for questions you may have or general discussion about Multi Trepanic Collagen Actuation (MCA) which is also known as Skin Needling. MCA is often used to stimulate the skin to naturally re-pigment after loss of pigment due to scarring etc.

I have heard about skin needling / MCA and someone suggested to me that it might be good to treat a patch of white skin on my face, I had fraxel laser treatment to improve my skin but I have lost skin pigment in a couple of patches that are about the size of a 10c and 20c coin. I wonder if MCA would improve it?

Could you please explain what MCA is and what is involved and exactly how does it work.

Hi Linda welcome and thank you for posting such an interesting question on the forum.

Multitrepannic Collagen Actuation or MCA uses a dry needling technique to stimulate the bodies own natural collagen and melanin producing cells, this process can be beneficial in the treatment of hypo-pigmented (lack of colour) skin, it can help to flatten and soften scars and improve the appearance of wrinkles, and is helpful in repairing skin that has been marked by acne or chicken pox.

MCA is performed using the micro-pigmentation (cosmetic tattooing) device fitted with a special needle and no pigment is used, hence the term dry needling. The area to be treated is pricked all over using a specific technique, this gives the skin the appearance of being grazed, once the initial surface healing has completed, which usually takes about 7 days, then the area needs to be exposed to UV light either by sitting in the sun or using a sunbed for designated periods of time that are discussed at the time of your treatment.

The body's reaction to the trauma of needling is to produce collagen in the dermis layer of the skin as this starts the repair process within the deeper skin. When the area is exposed to the UV light the melanocyte cells in the epidermis layer of the skin produce melanin to protect the collagen from the UV light, once the collagen has finished repairing the skin the melanin remains in the area, giving the skin back some of its lost colour. In the treatment of scarring or wrinkles the collagen production that has been stimulated can improve the skin defects and make them less visible.

With any area of hypo-pigmentation it may be worth considering starting your treatment plan with MCA as a way of getting the body to produce melanin in the affected skin area as that may produce a more natural re-pigmentation, if MCA does not achieve the desired results then skin coloured pigments could be used as a second choice. Unfortunately with some forms of hypo-pigmentation such as Vitiligo the skin will not respond to MCA, in those circumstances then a skin coloured pigment can be used to camouflage the hypo-pigment the area.

MCA and skin camouflaging are advanced procedures and should only be performed by specialist ParaMedical Cosmetic Tattooists who have been trained in those areas.

I hope this has answered your questions regarding this procedure.

Great answer, thanks for explaining it so well I have asked about it at a beauty salon once before but they just gave me a muddling reply that made no sense. But I think I understand how it works now.

That actually sounds like a good option for me and I like the idea of it stimulating my skins own pigment to come back again rather than covering it with makeup all the time. Also I did not realise that you could tattoo in skin coloured pigments as well, interesting as I have never heard of that before.
