The term is often used in the context of laser ablation, a process in which a laser dissolves a material's molecular bonds.

Surface ablation of the skin (dermabrasion = resurfacing because it induces regeneration) can be carried out by chemicals (chemoablation), by lasers (laser ablation), or by electricity (fulguration). Its purpose is to remove skin spots, aged skin, and wrinkles, thus rejuvenating the skin.
Ablation therapy using radiofrequency waves on the heart is used to cure a variety of cardiac arrhythmias.
