Exclusion Criteria: A subject is ineligible to enter the study if he/she meets 1 or more of the following criteria: 1. Subject has any dermatological disorders of the skin within 20 cm of the Treatment Areas with the possibility of interfering with the application of the IP or examination method, such as fungal or bacterial infections, psoriasis, eczema, folliculitis, notable scarring (linear scar \> 2.5 cm, etc.), or skin atrophy at Visit 2/Baseline. 2. Subject has any skin pathology or condition that, in the investigator's opinion, could interfere with the evaluation of the IP or requires use of interfering topical, systemic, or surgical therapy at Visit 2/Baseline. 3. Subject has any visible inflammatory skin disease, injury, or condition of their skin that could compromise subject safety and/or interfere with the evaluation of local or systemic assessments performed during the study. 4.
