  • Agrees to the use of Naftin Gel between the toes to prevent/control tinea pedis

Exclusion Criteria:

  • Pregnancy, breastfeeding or planning to become pregnant
  • History of cutaneous photosensitivity, porphyria and hypersensitivity to porphyrins or photodermatoses
  • Any skin pathology or condition that could interfere with the evaluation or that requires the use of interfering topical or systemic therapy
