Dexamethasone should not be used externally to reduce the swelling of total eyelid incision. If you need to reduce the swelling, you can choose to apply cold and hot compresses. Dexamethasone, as a corticosteroid hormone, has anti-inflammatory, anti-allergic and immunosuppressive effects, but its topical dosage form is used for limited pruritus, neurodermatitis, contact dermatitis, seborrheic dermatitis and chronic eczema. It is not suitable for external use on wounds, and its blind use may increase the possibility of local infection, while delaying the healing of incisions and affecting the recovery after double eyelid surgery. The oral form is mainly used for allergic and autoimmune inflammatory diseases. For example, connective tissue disease, severe bronchial asthma, dermatitis and other allergic diseases, ulcerative colitis, acute leukemia, malignant lymphoma and so on. Swelling after full eyelid incision is not one of the above mentioned conditions and is not suitable. If you need to reduce the swelling after full eyelid surgery, you can choose ice packs to apply cold compresses on the affected area to reduce the postoperative swelling. After the acute stage, choose hot salt packs to apply hot compresses on the affected area to promote blood circulation and help hematoma dissipate. If you need to reduce swelling after surgery, please consult your surgeon or a regular hospital to avoid self-medication.
