Laser for Hyperhidrosis

Hyperhidrosis is sweating that is excessive for the body's cooling needs. Energy-based procedures may deliver controlled heat to sweat-gland-containing skin, while other technologies use electrical current or targeted injections. The term laser is sometimes used loosely, so ask which device is actually being proposed and whether it is designed for underarms, hands, feet, or another area.

Sweating can also irritate skin and contribute to heat rash, intertrigo, or tinea versicolor. Treating those problems is different from reducing sweat production.

Record where sweating occurs, whether it happens during sleep, and which products or medicines you have tried. A clinician may first consider prescription antiperspirant, iontophoresis, or Botox for sweating, depending on the site and severity. Tell the clinician about implanted devices, reduced sensation, skin infection, and medicines that affect sweating.

After an energy procedure, keep the area clean as directed, avoid friction and intense heat while the skin settles, and watch for changes in sensation. Attend planned reviews so the response and skin condition can be checked.

Get prompt advice for severe pain, blistering, spreading redness, drainage, fever, or persistent numbness after treatment. New generalised sweating, night sweats, dizziness, chest symptoms, or sweating with unexplained weight change should be medically assessed rather than treated as a cosmetic concern.

Ask which technology is being used, which glands and body area it targets, what alternatives fit your pattern, how skin sensation is protected, and which aftercare symptoms need review.
