How to Prevent Scars After Double Eyelid Revision Surgery (Two-Line Lowering)
Learn how to prevent scars after double eyelid revision surgery (two-line lowering) with a comprehensive guide covering post-operative care, scar management, and key precautions for a smooth, natural outcome.

Many people choose double eyelid revision surgery (two-line lowering) to improve what is known as ‘sausage eyes’, where the double eyelid line is too high or thick. Two-line lowering is a delicate procedure that lowers the existing high double eyelid line and releases the adhesion of the old line.
However, because it involves dissecting (separating) existing scar tissue and creating a new line, if post-operative scar prevention and management are not properly carried out, the old multiple folds may reappear, or adhesive scars may remain.
Today, based on medical facts, we provide a key guide to scar prevention by period to achieve smooth and natural eyes after two-line lowering.


1. Medical Reasons for Scarring After Two-Line Lowering
The essence of two-line lowering surgery is to release the strong fixation (adhesion) of the existing double eyelid and create a new line of adhesion below it. When our skin is injured, it undergoes a ‘fibrotic process’ to heal back to its original state. If proper management is neglected during this time, the following side effects may occur:
Re-adhesion of the old line: The previously released double eyelid line re-adheres during the wound healing process, causing multiple folds in the eye.Hypertrophic scar (scar tissue): Excessive proliferation of collagen in the incision area, resulting in a red, hard, raised scar.Discoloration and sunken scars: Darkening or depression of the skin tone due to strong tension or inflammation in the surgical area.


2. Two-Line Lowering Scar Prevention Protocol by Period
It takes at least 6 months to 1 year for the skin tissue to fully stabilize after two-line lowering. Period-specific management that does not miss the golden time is essential.
① Immediately after surgery ~ Before stitch removal (1 week): Thorough swelling management and stability
Avoid increased intraocular pressure: Actions such as bending your head, rubbing your eyes, or lifting heavy objects increase tension in the incision area, causing scars to widen. Sleep with your head elevated above your heart.
② After stitch removal ~ One month (Golden Time): Early adhesion prevention and start of scar ointment
Use of scar ointment and sheets: After stitches are removed and the wound is completely closed (usually 1-2 days later), apply the prescribed scar ointment (silicone gel component) thinly morning and evening.
Eye-opening exercises: Lightly perform medically instructed eye-opening exercises to help the newly created lower line settle correctly and prevent the old upper line from re-adhering.
③ 1 month ~ 3 months after surgery (Scar tissue formation period): Management of redness and hardened tissue
Consider scar tissue care and scar injections: During this period, the wound area temporarily becomes red and hard, known as the ‘scar tissue cycle’. While this is a natural process, if it becomes excessively raised or hypertrophic, visiting the hospital for early scar injection treatment (steroid components, etc.) is effective in preventing adhesion.
UV protection: If the wound area is exposed to sunlight, melanin pigment can deposit, leaving dark scars. Wear sunglasses or a hat when going out and apply sunscreen thoroughly.


3. Key Summary (Q&A)
Q. How can I prevent the old line from reappearing after two-line lowering?
A. The most important thing is to accurately perform the eye-opening exercises instructed by the hospital in the early stages of surgery to help the new line adhere. Additionally, silicone-based scar management products should be used consistently to inhibit excessive intercellular bonding that occurs during the wound healing process.
Q. Can I massage the scar tissue at home when it appears?
A. Excessive stimulation or strong massage within one month after surgery can actually cause internal tissue inflammation and worsen scars. Do not rub hardened areas vigorously with your hands; it is safer to consult with the operating specialist and receive appropriate injection therapy or laser treatment.
As two-line lowering is a complex revision surgery that realigns the anatomical structure of the skin, the patient's post-operative care efforts account for 50% of the outcome, as much as the medical team's delicate skills. Please strictly adhere to the precautions for each period to regain smooth and natural eyes without side effects.
Post-operative care methods may vary depending on individual constitution or specific surgical methods, so it is essential to prioritize following the instructions of your attending specialist.

Frequently Asked Questions
How can I prevent the original double eyelid line from reappearing after a double-line revision surgery?
Yes, you can prevent it by practicing eye-opening exercises and using scar ointment. It is most important to accurately perform the eye-opening exercises guided by the hospital to help the new line adhere. Additionally, consistently apply silicone-based scar management products to suppress excessive cell-to-cell bonding.
Is it okay to massage at home if scar tissue forms?
No, strong massage should be avoided within one month after surgery. Excessive stimulation can cause inflammation in the internal tissues, worsening the scar. Do not rub hardened areas, and it is safer to consult with a specialist for injections or laser treatment.
What should I be careful about immediately after surgery until the stitches are removed?
It is important to avoid actions that increase intraocular pressure and to manage swelling. Actions such as bending your head down, rubbing your eyes, or lifting heavy objects can increase tension on the incision site and widen the scar, so they should be avoided. When sleeping, it is best to keep your head higher than your heart.
When should I start applying scar ointment after double-line revision surgery?
You can start applying it after the stitches are removed and the wound is completely closed. Typically, it is recommended to apply a thin layer of the prescribed silicone gel scar ointment morning and evening, starting 1-2 days after stitch removal, to prevent initial adhesion.
Is sun protection necessary when going out after surgery?
Yes, sun protection is essential for scar prevention. If the wound area is exposed to sunlight, melanin pigment can deposit, leaving a dark scar. Therefore, when going out, you should wear sunglasses or a hat and carefully apply sunscreen.
