Focal hyperhidrosis is excessive sweating that occurs in specific areas of the body—most commonly the underarms, palms, or feet. This can interfere with daily activities and impact confidence. Neuromodulator/Tox injections are an effective, FDA-approved treatment that work by temporarily blocking the nerve signals that trigger sweat production in the treated area. Results typically last 4–6 months, providing long-lasting dryness and relief without the need for surgery or harsh medications.
