Baggy eyelid
There are 3 main factors of environmentally induced periocular aging change:
1. photo aging
2. gravitational force
3. facial expression
Aging change under the eye and occur mostly from gravitational force. On the lower eyelid, changes can be evidenced as baggy eyelid and double convexity deformity.

Correction of the aging mid-face
1. Baggy eyelids are caused by prolapse of orbital fat pad.
With aging, the orbital septum stretches, bulges, or dehisces, allowing fat to prolapse anteriorly. Lower eyelid orbital fat pad volume also increase with age make baggy eyelid more prominent.
Surgical correction:
Baggy eyelid can be managed by lower blepharoplasty. Repositioning and occasional excision of bulging fat are the main step of the lower eyelid blepharoplasty.
Transcutaneous approach was traditionally used but the transconjunctival approach is now preferred by most cosmetic surgeons. In the transconjunctival approach, there is less likely to be complications, such as eyelid retraction. Additionally, no skin scarring is another advantage of the transconjunctival approach.
2. Double convexity deformity is the combination of baggy eyelid and descending midface.
Drooping malar fat pad produce the skeletonization of the inferior orbital rim. Hollowness of the inferior orbital rim between prominence baggy eyelid fat and bulge of descending malar fat develops deep orbital sulcus called double convexity deformity.
Surgical correction:
Lysis of orbitomalar ligament and midface lift can be performed concurrently with lower blepharoplasty. Orbital fat transposition or liposuction with fat injection procedure will alleviate deep orbital sulcus and smoothen lower lid-cheek junction area.
