My concern is what I believe to be Dennie Morgan folds. They weren't there a week ago. How can I get rid of them? (photo)

Dennie Morgan lines are not really Dennie Morgan lines.  Dennie Morgan lines is another organized, unscientific lie that pediatricians make to mothers.  The line is caused by a muscle roll in the lower eyelid close to the eyelid margin. This may occur in the developing infant eyelid and can cause a small crease in the lower eyelid close to the eyelashes. The pediatricians with no real evidence declared this line and the under eye dark circles related to allergies. They is not true. In your case, your under eye line is just an under eye (baby) wrinkle. Under eye fillers would be very helpful here.  Look for someone who knows what they are doing. It is a fussy service. How fussy? I see many patients who fly to Beverly Hills from Chicago to get their under eye fillers.

The appearance of the fold immediately under the eyelashes is sometimes called a Dennie Morgan fold. This name may or not signify what is actually happening in your eyelids... The off and on nature of the issue in your case implies a medical cause. I have seen this in patients with blepharitis (eyelid inflammation) and various skin conditions (eczema, etc.). It is likely that a topical treatment may help. If not, a very small skin excision in the lash line can be useful.

The lines are the bottom of the herniated fat from the lower eyelid. The best solution for that is lower eyelid blepharoplasty. RegardsDr Janjua
