How long does it take for double eyelid scar hyperplasia to disappear?
Generally speaking, scar hyperplasia refers to hypertrophic scars. The duration for the disappearance of hypertrophic scars on the double eyelids mainly depends on the severity of the hypertrophic scarring. Mild cases may gradually fade and disappear within 3-6 months. Severe cases may take 1-2 years to disappear. If the scars persist without fading, it is recommended to seek medical treatment. Detailed analysis is as follows:

If the hypertrophic scar on the double eyelid is relatively mild and newly formed, with light pigmentation and minimal aesthetic impact, it usually can be treated under a doctor's guidance using medications such as compound acetic acid dexamethasone cream, polysulfated glycosaminoglycan cream, or scar removal ointments. Typically, after 3-6 months, the hypertrophic scar will gradually fade and eventually disappear, returning to a natural appearance.
However, if the hypertrophic scar on the double eyelid is severe or if the eyelid surgery caused significant trauma, and the scar has been present for a long time with a black or brown color, the fading process may be prolonged, potentially requiring 1-2 years for complete resolution. In some cases, the scar might not fade completely. In such situations, timely medical consultation is recommended, and scar excision surgery may be considered. This treatment involves removing the scar tissue through surgical excision.
It should be noted that during the recovery period of hypertrophic scars, one should avoid frequently touching the wound with hands to prevent interference with healing. Additionally, before the wound fully heals, strenuous exercise and heavy sweating should be avoided to prevent bacterial infection of the wound.
