Botox Therapy for Hyperhydrosis: How I Do It

  • Charles B. Slonim


Hyperhidrosis is the poor man’s detection method for determining where to inject botox:
  1. 1.

    Paint the area (e.g., axilla) with betadine solution (a betadine wipe will do)

  2. 2.

    Allow the betadine to dry

  3. 3.

    Apply a thin layer of cornstarch or fine talc powder over the betadine

  4. 4.

    Shine a handheld spotlight with a 100 W bulb directly on the area

  5. 5.

    The areas of hyperhidrosis will be stimulated and the moisture will cause the betadine to “bleed” through the white powder or cornstarch

  6. 6.

    Photograph the area for documentation

  7. 7.

    Apply a layer of a topical anesthetic (e.g., betacaine, EMLA, etc.)

  8. 8.

    Inject Botox into the dermis in a grid pattern in the targeted area with approximately 1 cm between injections

  9. 9.

    Use 2.5 units in 0.05 cc per injection site
