“…In addition, fair skin is more sensitive to skin aging (Guinot et al, 2002;Nagashima et al, 1999). These findings support the observation that fair skin tends to wrinkle and sag earlier in life (Rawlings, 2006;Tsukahara et al, 2004), because fair skin is thinner and is more susceptible to NIR damage to the underlying frontalis, orbicularis oculi, and platysma muscles than dark skin (Tanaka & Matsuo, 2008).…”

“…The advanced loss of laxity and tone, which is a characteristic fea ture of aging ocular adnexal tissue, results in sagging eyelids (2)(3)(4)(5) . His tologic examination of dermatochalasis specimens shows an increased number and dilation of lymphatic vessels in conjunction with widely spaced collagen bundles.…”

Life expectancy is increasing in most countries. With increasing age, many in dividuals may develop involutional ophthalmic diseases, such as eyelid aging. Dermatochalasis, ptosis, ectropion, and entropion are common disorders in middle-aged and older adults. This review outlines the pathophysiology and clinical manage ment of these involutional eyelid disorders. Recently, a decrease in elastic fibers with ultrastructural abnormalities and an overexpression of elastin-degrading enzymes have been demonstrated in involutional ectropion and entropion. This may be the consequence of local ischemia, inflammation, and/or chronic mechanical stress. Eyelid aging with progressive loss of tone and laxity may affect the ocular surface and adnexal tissues, resulting in different clinical symptoms and signs. Surgical management depends on the appropriate correction of the underlying anatomical defect.

“…All these findings suggested that NI would be a potential parameter for characterizing skin aging. Some studies [6], [15] reported the effect of a high body mass index (BMI) was associated with looking younger than one's age. In this research, we noticed that an individual with higher BMI had a denser skin texture appearance, e.g., smaller grid areas and more intersections, so we supposed that the skin texture parameters were proportional to BMI.…”

Abstract. This paper presents a model of detection age which quantifies the appearance changes of human skin at different stages of aging without traditional skeleton. We provide a novel method to extract age-related primitive features from skin surface images obtained by a digital camera, including skin surface heterogeneity parameters of the standard deviation of gray (Std) and the information entropy (Entropy) of skin images, the skin surface texture variations parameters of the mean area of the grids (MA) and the number of intersections (NI). Skin surface images of 97 individuals have been analyzed by our image processing program. The results show that the four parameters were statistically correlated with age, indicating their potential for the routine evaluation of skin aging.
