Double eyelid scar belongs to hyperplastic scar, and the methods of removing it include X-ray radiation therapy, intradermal injection therapy, surgical treatment, topical medication and so on. 1. X-ray radiation therapy: generally for early lesions, X-ray radiation therapy is usually used to slow down the proliferation of vascular endothelial cells and fibroblasts to reduce and remove scar proliferation. 2. Intradermal injection therapy: For patients who cannot use X-ray therapy, glucocorticoid therapy, such as compound betamethasone and triamcinolone acetonide, can be injected intradermally to play the role of anti-inflammatory and inhibit scar proliferation. 3. Surgical treatment: For those with large double eyelid scar, surgical excision treatment can be taken, and after the operation, combined with X-ray treatment or local injection treatment is also needed, so as to inhibit the recurrence of postoperative scarring. 4. Topical medication: patients can also use topical glucocorticosteroids, such as compound hydrocortisone cream, mometasone furoate ointment, etc., as well as topical retinoic acid ointment, to alleviate local symptoms. It is recommended that after diagnosis, patients under the guidance of a professional physician reasonable treatment, not blindly self-medication, to avoid delaying the condition. Drugs need to be used in accordance with medical advice.
