Used in topical treatments for actinic keratosis, a precancerous skin condition caused by prolonged sun exposure. The compound works by promoting cell death in abnormal skin cells and stimulating an immune response in the affected area. It is valued for its rapid action, often showing results within weeks of application. Due to its potent biological activity, it is formulated in low concentrations to minimize skin irritation while maintaining efficacy. Ongoing studies explore its potential in treating basal cell carcinoma.
