Why does a double eyelid line loosen over time?
A loosened fold usually traces back to how the line was fixed — thread tension, tissue thickness, and swelling all play a part.
Non-incisional double eyelid surgery holds the fold with internal sutures rather than a skin-to-muscle scar. When that internal fixation stretches or gives way, the line becomes shallow or disappears. How often this happens varies from person to person.
What weakens the fold
Thick eyelid skin, abundant fat, and a strong orbicularis muscle put constant load on the suture loop, so heavier lids loosen more readily. Vigorous eye rubbing, large weight changes, and residual swelling in the early months can also stretch the fixation before scar tissue matures.
A partially loosened line sometimes settles as swelling resolves, while a fully released fold generally needs re-fixation. An oculoplastic specialist can examine the lid and advise whether observation or a revision method suits the eye — outcomes differ by anatomy, so an in-person consultation is the sensible first step.
