“…Since the appearance of the face is one of the most important measures for the evaluation of facial ageing, many studies have attempted to use qualitative measures to evaluate the progression of facial ageing and the response to rejuvenation treatments via the use of facial photographs as a primary assessment tool. 3,4,[20][21][22] Few radiology studies have been used for the assessment of facial ageing. CT has been used to evaluate age-related changes in deeper facial structures such as facial bones.…”

Objectives: To investigate the location-specific tissue properties and age-related changes of the facial fat and facial muscles using quantitative MRI (qMRI) analysis of longitudinal magnetization (T1) and transverse magnetization (T2) values. Methods: 38 subjects (20 males and 18 females, 0.5-87 years old) were imaged with a mixed turbo-spin echo sequence at 1.5 T. T1 and T2 measurements were obtained within regions of interest in six facial fat regions including the buccal fat and subcutaneous cheek fat, four eyelid fat regions (lateral upper, medial upper, lateral lower and medial lower) and five facial muscles including the orbicularis oculi, orbicularis oris, buccinator, zygomaticus major and masseter muscles bilaterally. Results: Within the zygomaticus major muscle, age-associated T1 decreases in females and T1 increases in males were observed in later life with an increase in T2 values with age. The orbicularis oculi muscles showed lower T1 and higher T2 values compared to the masseter, orbicularis oris and buccinator muscles, which demonstrated small age-related changes. The dramatic age-related changes were also observed in the eyelid fat regions, particularly within the lower eyelid fat; negative correlations with age in T1 values (p , 0.0001 for age) and prominent positive correlation in T2 values in male subjects (p , 0.0001 for male 3 age). Age-related changes were not observed in T2 values within the subcutaneous cheek fat. Conclusions: This study demonstrates proof of concept using T1 and T2 values to assess agerelated changes of the facial soft tissues, demonstrating tissue-specific qMRI measurements and non-uniform ageing patterns within different regions of facial soft tissues.

“…Periorbital agerelated changes include crow's feet and lower eyelid rythides, scleral show, infraorbital hollowing, herniated fat pads, excess upper and lower lid skin, festoons, and eyelid hooding. In addition, attenuation of the lateral canthal tendons results in loss of the youthful architecture of the eye secondary to a decrease of the aesthetically pleasing upward tilt [7,15,17,18,[22][23][24][25][26][27]. The change in the lateral canthal complex position is functionally important, as its changes contribute to lower eyelid laxity, which may result in rounding of the lateral commissure and narrowing of the palpebral fissure [6, 8-12, 14, 28].…”

“…Superficial muscle thinning is induced by chronic NIR exposure, which ultimately leads to superficial tissue aging and skin ptosis [14] [19]. Fair skin tends to wrinkle and sag earlier in life [28] [29], and characteristic age-related skin changes occur at a more accelerated rate in Caucasians [30]. Thus, patients seeking facelifts often have fair skin and/or a habit of sunbathing.…”

Objective: Humans are increasingly exposed to artificial light and electromagnetic wave radiation, in addition to solar radiation. Many studies have shown the biological effects of ultra-violet and near-infrared exposure, but few have extensively investigated the innate biological defenses within human tissues against visible light and near-infrared exposure. Herein, we investigated spectral properties of endogenous human biological defenses against ultra-violet to near-infrared. Methods: A double-beam spectrophotometer (190 -2700 nm) was used to measure the transmission spectra of a saline solution used to imitate perspiration, and oil to imitate sebum, as well as human skin, blood, adipose tissue, and muscle. Results: Saline (thickness, 0.5 mm) blocked 27.5% -98.6% of ultra-violet, 13.2% -34.
