RF microneedling works by creating controlled microdamage from both the ultra-fine needles and heat. This stimulates the body’s natural wound-healing response, kick-starting the biological processes that create new collagen and elastin. 

Aging and environmental damage (particularly sun damage) break down these essential structural proteins, and the rate of replacement slows over time. Procedures like RF microneedling can slow and even temporarily reverse this process, helping skin look and even act younger.
