What is double eyelid hypertrophy?
After undergoing double eyelid surgery, I experienced redness and swelling in the eyelid area, and the skin appears to have thickened, giving a sensation of an extra layer of skin. I looked it up and found it might be due to double eyelid hyperplasia. I would like to know, what exactly is double eyelid hyperplasia?

Doubling of the eyelid usually refers to abnormal thickening or excess of the skin tissue along the eyelid crease. This may be caused by post-surgical scar tissue formation, skin inflammation, localized infection, or congenital eyelid structural issues.
Double eyelid surgery is a common procedure that creates or enhances the eyelid crease by altering the eyelid's anatomical structure. After surgery, excessive collagen production during the wound healing process may lead to slight swelling or thickening along the eyelid crease, a phenomenon commonly referred to as hyperplasia.
This phenomenon typically appears about one month after surgery and may last for one to three months, although the exact duration varies depending on individual constitution. Double eyelid hyperplasia may affect appearance, making the eyelid crease look unnatural or overly prominent. For mild cases of hyperplasia, cold compresses and massage may help reduce swelling and promote recovery.
To prevent double eyelid hyperplasia, it is recommended to apply anti-scar medications appropriately after surgery and follow proper post-operative care. If hyperplasia has already developed, treatment options such as medication, laser therapy, or surgical intervention may be considered based on a physician's recommendation.
