Subjects taking systemic retinoids must be on a stable regimen for at least 4 weeks and agree to continue to take the medication consistently throughout the study.

Clinically stable and in good general health\n\nKey Exclusion Criteria:\n\n1. Subject has a physical condition or other dermatological disorder (e.g., atopic, seborrheic, or contact dermatitis, psoriasis, tinea infections, etc.) which, in the Investigator's opinion, might impair evaluation of the target areas or which exposes the subject to unacceptable risk by study participation\n2. Participation in another clinical study or treatment with an investigational agent within 30 days or 5 half-lives, whichever is longer\n3. Any condition or illness (including a history or current evidence of substance abuse or dependence) that, in the opinion of the Investigator, would impact a subject's ability to complete all study-related procedures and/or poses an additional risk to the assessment of safety of KB105\n4. Women who are pregnant or nursing\n5. Subject who is unwilling to comply with contraception requirements per protocol\n6.
