Hello, As per your case history, you are having Seborrheic keratosis. My treatment advice is: 1. Avoid sun exposure and use a good sunscreen lotion with SPF more than 30. 2. Apply a mild antibiotic cream like Fusiderm cream twice daily on it to prevent infection. 3. Only curative treatment is cauterization or laser ablation done by a dermato-surgeon. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Harshit Bhachech
