Efficacy Of 1470 Nm Laser In Non-Surgical Double Chin Removal And Facial Contouring: A Comparison Between Radial And Linear Optic Fibers

Background:Localized fat pertaining to the face especially beneath the chin, leads to the accruement of aged faces in the shape of roundness of cheeks, jowling and appearing of a double chin. Age-related alterations in subcutaneous white adipose tissue, decrease in skin elasticity, modification of the collagen and diminished dermal-fat adhesion influence these changes. The diode laser (1470 nm) has come as a non-surgical, minimally invasive way of reducing facial fat and skin tightening.Aim:This study aimed toassess the effectiveness and safety of the 1470 nm laser according to linear optic fibers in the non-surgical elimination of the fat in the chin and in contouring the face and compare it to the radial one, which facilitates effective fat reduction and skin tightening in the submental and mandibular areas.Methodology:Ten female patients with mild-moderate submental adiposity were subjected to a single treatment session of laser-assisted lipolysis under local tumescent anesthesia to treat submental adiposity using the 1470 nmdiode laser with linear optic fibers. Measures were evaluated with the baseline, 1, 3, and 6 months ultrasound imaging, adipometry, standardized photography, and patient satisfaction surveys. The safety and tolerability werealso observed.Results:The linear fiber method proved to show a significant decrease of the submental fat combined with the clearer outline of the chin and jawline, as well as an increase in skin tone and elasticity. Natural, gradual improvements of aesthetics and a minimal downtime were highly satisfying to patients. Means of skin texture and thickness maintained thinning of fat and an improved skin texture. The effect was minimal and undesirable effects of the procedure proved to be minimal due to the capability of the1470 nm wavelength to specifically target water and fat tissues in the body by virtue of its high absorption. Linear fibers also allowed more focused energy delivery in the cutaneous fat planes compared to radial fibers, improving precision and efficacy of treatment, especially in sensitive region of the face.Conclusion:The non-surgical technique of the 1470 nm diode laser with the linear optic fibers is safe and highly effective in reducing the amount of fat in the chin and achieving the shape of the face, causing disruption in the adipose tissue and removing the collagen. It gives optimal clinical and cosmetic results due to its optimal directional energy deposit; has minimal side effects, and recovery time as compared to radial fibers. The modality is a major breakthrough in minimally invasive facial rejuvenation that deals with fat reduction as well as skin laxity necessary in lower-face definition enhancement.
