Abstract
In elderly, most changes in the skin’s appearance are the result of chronic exposure to UV radiation from sunlight. This process, known as photoaging, differs clinically, histologically, and physiologically from intrinsic or chronological aging itself, although most patients and many physicians do not make the distinction. Photoaged skin is characterized by fine and coarse wrinkling, irregular mottled pigmentation, lentigines, roughness, sallowness, and telangiectasis.
Skin rejuvenation of aging and photoaged skin has recently attracted great attention. The minimally invasive procedure trend has certainly begun to sweep through facial plastic surgery with the growing popularity and acceptance of nonsurgical technique such as office-based procedures like microdermabrasion, chemical peeling, botox injections, the plethora of injectable filler materials, and the growing number of nonablative lasers. An effective non-surgical method of improving skin laxity has been sought, and the very recent appearance of nonablative RF, IR light, Fraxel laser technology and mesolift technique for skin tightening has become the focus of attention as a new method to treat more severe sequelae of photo-damage and intrinsic aging.
Noninvasive tissue tightening devices are currently not intended to replace the more dramatic effects of invasive surgical techniques. Results are always subtle and are not remotely as dramatic or reliably produced as those obtained from surgery. However, they are a good alternative to meet the needs of the patients who are averse to any surgical intervention, with no downtime and no incisions or scars. The skin contraction achieved is in the order of 1–3 mm. Although not dramatic, the changes are perceptible, especially when it comes to an eyebrow lift or softening of the nasolabial fold. The results have, therefore, a remarkable ‘‘natural look,’’ which plastic surgery rarely can match. Finally further refinement of the technology and treatment algorithms, nonablative tissue tightening may represent tool of growing importance to the future of skin rejuvenation procedures.
