Skin toning refers to the use of Q-Switched lasers for non ablative skin rejuvenation. This term is more common in Asian countries.
In skin toning, multiple passes of low-dose Q-Switched Nd:YAG are delivered through a large spot size to induce sublethal injury
to melanosomes causing fragmentation and rupture of melanin granules into the cytoplasm. This effect is highly selective for
melanosomes and leads to overall skin brightness. Moreover, the subthreshold injury to the surrounding dermis stimulates
the formation of collagen that results in tighter skin.
