Skin needling is also called micro-needling therapy or collagen induction therapy. it is a minimally-invasive non-surgical procedure for facial rejuvenation that involves the use of a micro-needling device to create a controlled skin injury.
As each fine needle punctures the skin, it creates a channel or micro-wound. the microchannels createdspontaneously close after 10 minutes so that epidermal barrier integrity remains intact.
The needles injure superficial dermal collagen strands and small blood vessels triggering a controlled cascade of inflammation including the release of platelet-derived growth factors transforming growth factor-alpha and beta connective tissue activating protein, connective tissue growth factor, and fibroblastgrowth factor. These lead to the production of new collagen, elastin, and capillaries.
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 and melasma
tightening sagging skin.
