Can microneedling make the skin more firm?

Every microneedling treatment creates controlled points of injury that will cause skin to repair, replace and return to more normal appearance.  That being said, I do not ever promote microneedling as a treatment for sagging skin.  Delivery of radiofrequency in a microneedling event with a system called Infini can significantly improve sagging skin.  Other systems that can help sagging skin include Thermi and Ultherapy.  The ultimate fix is surgical, but these systems can postpone the need for surgery for up  to 10 years.

Wonderful question.  Microneedling can stimulate collagen regeneration and when combined with PRP it can improve scars in a variety of skin types.  This includes acne scars, chickenpox scars and surgical scars. It can also rejuvenate and tighten the skin - thus making it firmer.   The expectations of treatment are pinpoint bleeding and localized irritation.  Side effects are rare when the correct technique is used.    

Microneedling has been a very desirable treatment for many due to the amazing results with little downtime. Microneedling also known as CIT (Collagen Induction Therapy) is a controlled injury to the skin. The skin needs collagen to heal, after the skin has been injured with the needling, the skin starts repairing with the collagen boost leaving your skin tighter, smoother, firmer, and rejuvenated!! Depending on the laxity in the skin, additional treatment such a laser skin tightening may help improve your overall results.
