Patent ID: 8262650

Claim:
A method of preventing regrowth of hair upon a patient's skin, said method comprising: determining the location and depth of at least one region of a dermal papilla during a telogen phase of hair growth, relative to the skin surface of said patient by acoustic imaging of an area of and beneath said patient's skin; selecting at least one region of a dermal papilla during a telogen phase of hair growth, to be treated, where the location and depth of said at least one dermal papilla region is indexed to a digital map produced during said acoustic imaging; transcutaneously focusing high intensity acoustic energy at a location and depth of said at least one dermal papilla region to be treated, wherein said focusing is in accordance with an indexed digital map; and applying sufficient high intensity acoustic energy to raise said at least one dermal papilla region to a sufficient temperature for a time sufficient to destroy said dermal papilla region, whereby regrowth of hair is prevented.
