How long should Ma Yinglong be left on before washing off?
Ma Yinglong usually refers to Ma Yinglong Musk Hemorrhoids Ointment. There is no need to deliberately wash it off after application. This ointment is for external use only; its active ingredients act directly on the affected skin or mucous membranes, gradually penetrating and being absorbed. The residual components are harmless and do not require additional cleaning. If symptoms such as increased redness, swelling, itching around the anus, or allergic reactions occur after using the ointment, medical advice should be sought promptly.

The formula of Ma Yinglong Musk Hemorrhoids Ointment is specially designed to suit the perianal skin environment. After application, it forms a protective film that continuously exerts effects of clearing heat, drying dampness, promoting blood circulation, and reducing swelling. Deliberately washing it off will remove this protective layer, interrupt the medication's action, reduce therapeutic effectiveness, and defeat the original design purpose of the formulation.
The ointment leaves minimal residue and has a mild nature, which does not irritate the perianal skin. It also helps reduce mechanical friction damage to the affected area. Excessive washing, especially with hot water or irritating cleansers, may disrupt the skin barrier around the anus, causing discomfort or worsening inflammation.
After applying the ointment, gently wipe away excess with a clean tissue to keep the perianal area clean and dry. Avoid prolonged sitting or standing to reduce pressure on the anal region. Maintain a light diet rich in dietary fiber to ensure smooth bowel movements and support recovery of the affected area.
