Treating the Under Eye Area with Soft Tissue Fillers



 

Under eye circles and puffiness can work together to create a tired appearance, making a young face look old and an older face appear even older. Many women obsess about under eye problems, creating a market for an endless and confusing array of products, including creams, gels, concealers, brighteners and rollerballs.

 

Lower lid blepharoplasty, which removes excess under eye skin and fat is a tried, true and well respected surgical option, but recently a nonsurgical fix has emerged. Hyaluronic acid, marketed as Restylane, Juvéderm and other soft tissue fillers, can be injected into the tear trough (crescent-shaped under eye area) to rejuvenate the appearance of the under eye area.

 

What causes dark circles?

Many factors contribute to dark circles, but the common denominator is heredity and genetics.

·       Most frequently, dark circles are created by volume loss in the under eye area that exposes the orbital bone, creating a hollow trough that shows up as a dark circle. The delicate eye area, with its extremely thin skin, is one of the first spots to reveal signs of aging.

·       Dilated blood vessels that sit close to thin under-eye skin are another cause of dark circles.

·       Airborne allergens, which cause blood to pool in the vessels under the skin, can worsen the appearance of dark circles. (Treatment for this may be as simple as an antihistamine pill.)

·       Aging, which causes skin to thin, can darken the eye area, as can certain medications such as birth control pills, which can dilate blood vessels.

·       Sun exposure makes dark circles worse.
 

Advantages of injecting soft tissue fillers in the under eye area

The overall aim for soft tissue filler injections in the under eye area is to improve rhytids (wrinkles) and thinning under eye skin (which leads to sagging), and to decrease bulging under eye fat as well as the tear trough depression. Here is some more information:

·       In the early 90s, plastic surgeons began to use fat, which was removed during blepharoplasty, to fill in the tear trough depression. This usually led to swelling for several weeks and occasional problems with lumpiness in the lower eyelids. With Restylane or Juvederm, if you are unhappy with results, you don’t have to wait. Results can be altered with Hyaluronidase; this product dissolves and degrades the hyaluronic acid product to reverse the results of the injections.

·       Soft tissue fillers may not only add volume to the depression of the tear trough, but can also be used to thicken the anterior lamella (lower eyelid skin and orbicularis muscle) of the lower eyelid, which can in turn hide a lot of the aging changes underneath.

 

Success of Under Eye Injections Depends on the Skills of the Injector

Injecting dermal fillers under the eye is a very "technique-dependent" procedure.

·       If you’re young, with significant tear-trough deformities, your problems are not due to thinning. A 22-years-old has a nice thick dermis, but may have a volume problem, so your practitioner may use a fairly deep injection technique.

·       If you have severe tear-trough deformities and a lot of thinning of the soft tissues, your physician may use a "sandwich technique," putting a large, thin, superficial sheet above the orbicularis oculi muscle (closes the eye) and then a similar sheet immediately below the orbicularis oculi, making a sandwich out of that muscle between sheets of the filler. This allows for more product in the area and also allows for more thickening of the soft tissues, which helps to hide a lot of the underlying aging problems across the entire lower orbit.

Bottom line: Find a physician who is board-certified in an appropriate specialty and then make sure that he or she has a long history of performing this procedure.

 

Who is the ideal candidate for under eye injections?

·       If you have a significant excess of bulging lower eyelid fat, you are not a good candidate. You would probably do better with a lower-lid blepharoplasty.

·       Any age is appropriate.

·       Men and women are appropriate. Women usually have a little more problem with thinning of the dermis; however, as men age, they have this problem too.

·       Fillers are also appropriate if you have had a previous lower eyelid surgery and now appear too hollow. Fillers can restore volume nicely.

·       For an older patient with almost translucent skin, fillers will not result in a perfectly smooth eyelid. The goal may be to decrease the apparent depth of the tear trough.

·        If your biggest problem is dark circles and not a puffy fat pad, be aware that this treatment is not a skin-lightening procedure. It will help with the shadowing, which contributes to dark under eye circles.

·       If you are looking for something permanent, you may be a good candidate for blepharoplasty.

 

How Will You Look Following this Procedure?

·       You will probably be asked to come back to the office around day 5  to see how the product settles after your treatment. 
 
·       Your lower eyelids be slightly swollen for about three days after treatment; this is not a zero-downtime procedure.
     

What is the main safety consideration?


·       Side effects can include bruising, swelling that can last for a week or two and on rare occasions an allergic reaction.

 

Although the FDA has not approved the use of Restylane and other soft tissue fillers for tear trough injection, many practitioners inject soft tissue fillers in the under eye area with success.  Choose a skilled, plastic surgeon, or ophthalmic surgeon who is experienced in under eye injections. Results last about eight months.
