When the small particles under the eye bags are cornus rash, they can be punctured and extruded by needle, laser or electrocautery to eliminate them. Sweat duct tumors do not need to be treated without other symptoms, but can be eliminated by surgery and laser when they are symptomatic and affecting the aesthetics. Most of the small particles under the eye bags are fat granules. Fat granules can include cornu rashes and sweat duct tumors, and their treatment methods are as follows: 1. Corns: the treatment is very simple, first of all, you need to disinfect the local skin, and then use a needle or scalpel to puncture the top of the corns and squeeze out the contents inside. If you have the condition, you can also give laser or electrocautery to remove. 2. Sweat duct tumor: it belongs to benign tumors and generally need not be handled when there are no other special symptoms. If it affects the aesthetics or is accompanied by itching and other symptoms, it can be eliminated by surgical excision or laser. When there are small particles in the bags under the eyes, they should be treated under the guidance of the doctor, and should not be punctured and extruded by themselves, so as not to cause infection.
