Hyperhidrosis Doctors in NYC

Dr. Leonard Grossman treats hyperhidrosis, or excessive sweating, at his Brooklyn, NYC practice. Botox microinjections reduce underarm, hand, foot or scalp sweating within days for about six months, and Botox is FDA-approved for underarm sweating. For a permanent reduction, he offers microcannula sweat-gland suction with Vaser ultrasound technology, a natural extension of his long experience with ultrasound liposuction.

Our Hyperhidrosis Services

Two hyperhidrosis treatments for excessive sweating: Botox injections and permanent Vaser sweat-gland suction.

Botox for Hyperhidrosis

Botox is microinjected into the underarms, hands, feet, scalp or face in one short session, reducing sweating within days for about six months.

Selective Ultrasound Treatment

Vaser ultrasound technology is used to target the sweat glands, the first step of Dr. Grossman’s permanent hyperhidrosis treatment.

Selective Suction Treatment

Through a microcannula, the treated sweat glands are suctioned out, offering a permanent reduction in sweating instead of repeat injections.

Two Ways to Stop Sweating

Explore Options for Excessive Sweating

Hyperhidrosis can soak clothing and make everyday contact uncomfortable. Dr. Leonard Grossman treats it two ways. Botox microinjections block the nerves that switch on overactive sweat glands, with results in a few days that last about six months. The injections use fine needles and feel like small pinches. There are no incisions or stitches, and most patients are back at work the same day. For patients who want a permanent answer, he performs microcannula suction of the sweat glands using Vaser ultrasound technology, at his Brooklyn center.
