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.
When you’re dealing with acne scars, finding anything that works even remotely to remove them is like finding the Holy Grail. But, when your scars are deeper than most and over the counter creams and medications won’t work, sometimes it’s a good idea to explore the option of a procedure in a dermatologist or plastic surgeon’s office.
Microneedling is used to create microscopic injuries in the stretch marks and the body responds by producing new collagen at the wound sites. This natural reaction by the body heals the tears in the dermis responsible for the stretch marks. As the outer layer of the skin is not affected by micro needling, the new collagen generated is used only to help heal the stretch marks. Stretch marks require a series of microneedling sessions, usually at 4-6 week intervals.Here is an example of how the crater-like texture of stretch marks has smoothed out and blended with the surrounding skin.
SEE BEFORE & AFTER
Treatment of acne scarring is always a challenge. Microneedling therapy or percutaneous collagen induction is a new addition to the treatment modalities for such scars and has been reported to be simple and effective in atrophic acne scar treatment. The aim of this study is to evaluate the clinical effect and objectively quantify the histological changes of acne scarring in response to skin microneedling.
