The tear trough is the groove at the junction between where the lower eyelid and the cheek. As we age, one of the changes which is commonly noticed and commented on is the appearance and gradual worsening of dark circles under the eyelids. This occurs due to the thinning of the overlying skin and soft tissue over the bony orbital rim.
In youth, due to the surrounding plump fat, thicker overlying skin and soft tissue surrounding this structure, this ligament is usually invisible. However, with age atrophy of the adjacent tissues and thinning of the skin occurs, leading to increased visibility of this deep attachment between the skin and orbital rim- the so called tear trough deformity.
Loss of volume at the junction between the upper cheek and lower eyelid, i.e. a worsening tear trough deformity, is an obvious sign of ageing.
Simple replacement of this lost volume without the need for surgery can lead to dramatic improvement. Hyalauronic acid is a natural tissue component produced by the body and can be used with excellent safety and effectiveness to treat tear trough deformity.
In most patients there is an immediate improvement with a reduction in the depth and width of the tear trough itself. Dark circles which are often due to shadowing within the trough itself similarly improve.
As with all safe hyalauronic acid-based fillers, there is very slow absorption of the injected material over time and these injections can quite safely be repeated if necessary. As one’s face slowly changes with time, cosmetic doctors have now recognised that non-permanent treatments are advantageous since they allow them to maintain harmony with the rest of the face.
Another major advantage of hyalauronic acid fillers is that they can quickly be reversed if the patient so desires.
