If Vitiligo is spreading quickly despite treatment with Dsorolen and Cosvate GM, it suggests the disease is currently active and may need adjustment in therapy. Do not increase or continue these medicines on your own, as they require careful monitoring; a dermatologist may consider options like phototherapy, stronger immunomodulators, or reviewing your current regimen. Avoid skin injury, manage stress, and consult a dermatologist soon for proper evaluation and updated treatment.
