Some lasers (ND-Yag, Erbium) can heat the skin without causing any lesion. This heat reaches the dermis and enables stimulating the fibroblasts which will then make new elastin and collagen fibers. This stimulation thus makes it possible to restore a certain elasticity combined to a tightening effect to the skin.
The retraction effect is immediate and then continues over time.
Radio frequency uses radio waves having a similar heat action at the level of the dermis and therefore has a tightening effect.
These treatments are offered straightaway to restore a tightening effect to the face’s skin, thigh belly but also after a session of cryolipolysis where it will act as a complement treatment and will restore part of the skin’s elasticity while the underlying fatty mass gradually resorbs after the cryolipolysis session.
