While many patients experience significant improvements after their initial miraDry treatment, studies indicate that an additional session often enhances results. Approximately 80% of individuals report a substantial decrease in underarm sweating following their second treatment. At the Laser & Skin Surgery Center of Pennsylvania, it is common for patients to require at least two sessions, scheduled 2 to 3 months apart, to achieve optimal results. This dual-treatment approach ensures a more comprehensive reduction in sweat production, providing patients with better long-term outcomes and increased satisfaction with the procedure.
