Microneedling falls under a process called collagen induction therapy, or CIT, which relies on skin’s natural ability to repair itself after an injury. You might find microneedling with radiofrequency (RF) and that without radiofrequency (RF). Unlike typical exfoliation treatments, RF microneedling penetrates past the stratum corneum and brings heat into the sub-dermis, stimulating and remodeling the collagen within. Think of it as a non-surgical facelift! There are many microneedling machines and devices now which you will find based on which med spa you go to.
