Microneedling, originally known as collagen induction therapy or percutaneous collagen induction (PCI), is now a well-documented superficial treatment option in atrophic acne scars and for skin rejuvenation.  Microneedling, as the term indicates, means the use of needles or 'microneedles' to achieve a therapeutic effect.  Microneedling is a method that some practitioners use to treat different skin conditions. The technique involves using multiple tiny, sterile needles to puncture the skin and cause physical trauma.  This trauma prompts the derma, a deeper layer of skin, to rebuild.  Microneedling may help address many skin-related complaints, including wrinkles, scarring, acne, alopecia, skin pigmentation issues, stretch marks, rosacea and loose skin, such as after weight loss or liposuction
