Hyperhidrosis is a condition in which sweating is in excess of that required for normal regulation of body temperature. Commonly affected areas in primary hyperhidrosis include axillae, palms and soles. Secondary hyperhidrosis can affect scalp, face, neck, back, groin and legs. Hyperhidrosis can negatively impact, employment, relationships, or other aspects of quality of life.

The investigators propose to investigate the use of a unique image-guided laser to specifically ablate eccrine sweat glands.
