Hello, It sounds like the medication you are referring to might be Clotrimazole or another antifungal medication containing Chlor in its name. Some antifungal medications, such as clotrimazole, ketoconazole, miconazole, can cause the skin to become shiny or greasy. This is usually due to the medication s ability to reduce the amount of sebum, or oil, produced by the skin s glands. Sebum is a natural lubricant that helps to protect and moisturize the skin, but when it is overproduced, it can contribute to acne and other skin conditions. When antifungal medications reduce the amount of sebum on the skin, it can make the skin appear shiny or greasy. This effect is usually temporary and will go away once the medication is discontinued. It is not usually a cause for concern and is not a sign of any serious side effects. Long-term use or misuse of these medications may sometimes lead to these side effects, including shiny skin, skin irritation, redness, or other changes in skin appearance. If you are experiencing shiny skin as a result of using an antifungal medication, you can try using a mild, non-comedogenic moisturizer to help keep the skin hydrated and prevent dryness. It is also important to follow the instructions provided by your healthcare provider or pharmacist, and to avoid using more medication than recommended. Also you can always consult your dermatologist. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Haneef Abbasi, Internal Medicine Specialist
