Skin needling, also called microneedling therapy, collagen induction therapy (CIT), and percutaneous collagen induction (PCI), is a minimally invasive skin-rejuvenation procedure that involves the use of a device that contains fine needles. The needles are used to puncture the skin to create a controlled skin injury. The device is a pen shaped studded with 12 very fine needles. It is a medical device used in micro needling to break down old scar tissue and to stimulate skin cells to proliferate. This cell multiplication results in the formation of new tissue layers of elastin and collagen fibers as well as in new capillaries for an improved blood supply.
Most people will experience redness and mild swelling in a similar way as mild sunburn for 24-48 hours and there may be minimal pin-point bleeding and/or bruising. Within a week or two, you will notice that your skin is smoother and more radiant looking but the full effects won’t be seen until a few months later. Micro-needling can be safely repeated every 4-6 weeks until you achieve the desired results. For collagen induction we recommend to start with 3 treatments, but with a minimum separation time of 4 to 6 weeks between treatments. For scar reduction an average of 3 to 6 treatments are recommended.
