Used in dermatological treatments for skin disorders such as psoriasis and vitiligo due to its photosensitizing properties when activated by UV light. Enhances repigmentation in vitiligo patients by stimulating melanocyte activity. Investigated for its potential in photodynamic therapy for certain skin cancers. Also found in some cosmetic formulations aiming to increase skin sensitivity to sunlight, though such use is limited due to risk of phototoxic reactions. Shows antimicrobial activity in laboratory studies, suggesting possible use in topical antiseptics. Research explores its role in modulating drug metabolism enzymes, which may affect the bioavailability of co-administered medications.
