Derma needling, also called micro-needling therapy or collagen induction therapy, is a minimally-invasive non-surgical and nonablative procedure for facial rejuvenation that involves the use of a micro-needling device to create controlled skin injury.
As each fine needle punctures the skin, it creates a channel or micro-wound. The controlled injury triggers the body to fill these micro-wounds by producing new collagen and elastin in the papillary dermis. In addition, new capillaries are formed. This neovascularisation and neocollagenesis following treatment leads to reduction of scars and skin rejuvenation, i.e., improved skin texture, firmness and hydration.
Professional skin needling is considered to be one of the safest skin treatment procedures. Unlike chemical peels, dermabrasion and laser treatments, skin needling causes minimal damage to the skin.
Skin needling is effectively used for:
- Reducing scars (including hypertrophic scars) caused by acne, surgery or thermal burns
- Fading stretch marks
- Reducing fine lines and deep wrinkles
- Dyspigmentation e.g in melasma
- Tightening sagging skin.
The treatment can be performed in an office setting and does not need any extensive special training or expensive instruments. The procedure is well tolerated and well accepted by the patients. It is cost-effective, and can be done on areas of skin not suitable for peeling or laser resurfacing, such as near eyes.
As opposed to ablative laser resurfacing, the epidermis remains intact and is not damaged. For this reason, the operation can be safely repeated if needed.
Treatment does not result in a line of demarcation between treated and untreated skin, as usually occurs with other resurfacing procedures. This allows for specific areas of scarring to be treated without the need to “blend” or “feather” at the treatment edges.
