“…Small wrinkles also form, leading to aging of the skin. The moisturizing capabilities of the elderly falls below those of the young (21), but the present study showed that the moisture content of the skin fell substantially with photoaging due to UVB irradiation, compared to the non-photoaging groups. However, since it was also confirmed that the LST group had higher moisture content than the water group, lotus seed tea intake has been shown to inhibit drying of the skin due to UV radiation to a certain degree.…”

Lotus (Nelumbo nucifera Gaertn.) seed is widely used as a traditional medicine in countries of Asia. Among many functions of the lotus seed, one interesting activity is its skin protection from the sunlight and scar. In this study, we focused on the skin protective property of lotus seed tea against ultraviolet B (UVB) irradiation. Two groups of a hairless mouse model, water as control (water group) and lotus seed tea (LST group), were administrated a fluid drink water for six months. After 6 month of administration, UVB exposure was carried out to both groups for another 3 months. During and after the administration, the skin moisture content and the morphological and histopathological analyses through biopsy were carried out. Prior to UVB irradiation, no significant difference was discovered in the skin moisture content for the water group and LST group (P＜0.05). However, drastic changes were observed after the UVB treatment. The LST group showed a clear evidence of skin protection compared to the control group (P＜0.05). The moisture content, epidermal and horny layer thickness, and protein carbonyl values all revealed that the intake of the lotus seed tea enhanced protection against UVB exposure. As a result, the long-term intake of the lotus seed tea showed the effect of preventing loss of skin moisture, mitigating the formation of abnormal keratinocytes, and contributing to protein oxidation inhibition.

“…The speed of propagation of the acoustic wave on the skin surface is inversely proportional to the stiffness and density of the tissues (Potts et al, 1983(Potts et al, , 1984Davis et al, 1989;Vexler et al, 1999). As a result, skin tension lines (Borges, 1984;Piérard and Lapière, 1987) influence RRTM (Nizet et al, 2001).…”

“…These aspects have been studied so far using different instrumental methods based on distinct physical principles. Among them, the assessment of the velocity of elastic shear wave propagation represents a promising approach (Potts et al, 1983(Potts et al, , 1984Serup, 1985;Dorogi et al, 1986;Davis et al, 1989;Pereira et al, 1990;Mridha et al, 1992;McHugh et al, 1997;Enk et al, 1998;Vexler et al, 1999;Nizet et al, 2001). Indeed, the propagation of shear waves has been shown to change with age (Potts et al, 1983(Potts et al, , 1984Davis et al, 1989;Pereira et al, 1990).…”

Background: The in vivo visco-elastic characteristics of skin depend on a series of physiopatho-logical parameters. Among them, the age-related intrinsic tensile properties and the preconditioning of the tissues set under tension by the hypodermal volume might be of importance. Aims: To revisit the influence of age and body mass on the firmness and mechanical anisotropy of the skin as determined by the velocity of the shear wave propagation. Method: Resonance running time measurements (RRTM) were performed on the mid volar forearm in 110 adults of both sexes. In each subject 16 RRTM were collected at four different precise angles with regard to the limb axis. We recorded the lowest, the highest and the mean multidirectional RRTM as well as the coefficient of variation (CV) of the latter value. In addition, the body mass index (BMI) was calculated. Results: Age and BMI did not influence the minimum RRTM. In contrast, the maximum RRTM as well as the mean and CV of the multidirectional RRTM, significantly rose in a progressively increasing proportion of the subjects older than 60 years. These changes were only encountered in subjects with a normal BMI ranging from 18 to 25. Sex-related differences were not disclosed. Conclusions: The intrinsic skin tension lines identified by the minimum RRTM are not significantly altered with age and BMI variations. In contrast, skin laxity identified by larger maximum and mean multidirectional RRTM may increase after 60 years of age in subjects with a normal BMI. This is accompanied by increased skin mechanical anisotropy identified by CV values of the multidirectional RRTM over 40%.

“…Dehydration is clinically assessed as turgor or the ability of the skin to return after deformation (Dorrington 1981). Turgor may be exacerbated in older people by reduced skin moisture content (Potts et al 1984), altered skin elasticity (Daly and Odland 1979), or poor peripheral blood flow (Evans et al 1993).…”

Age-related changes in cutaneous sensation in the healthy human hand

AGE

Cutaneous sensation deteriorates with age. It is not known if this change is consistent over the entire hand or if sensation is affected by changes in skin mechanics. Cutaneous perceptual thresholds were tested at eight sites in the glabrous skin and two in the hairy skin of both hands in 70 subjects (20-88 years), five male and five female per decade, using calibrated von Frey filaments, two-point discrimination, and texture discrimination. Venous occlusion at the wrist (40±10 mmHg) and moisturizer were used to alter skin mechanics. Cutaneous thresholds increased significantly with age (p<0.001); von Frey thresholds were 0.04 g [0.02-0.07] (median and interquartile range) in the 20s and 0.16 g [0.04-0.4] in the 80s, with differences between hands for older females (p00.044) but not males. The pattern of changes in cutaneous sensation varied according to the site tested with smaller changes on the fingers compared to the palm. Two-point discrimination deteriorated with age (p00.046), but with no interaction between sex, handedness, or changes in skin mechanics. There were no significant differences for texture discrimination. Changes in skin mechanics improved cutaneous thresholds in the oldest males after moisturizing (p00.001) but not otherwise. These results emphasize the complex pattern of age-related deterioration in cutaneous sensation with differences between sexes, the hands, sites on the hand, and the mode of testing. As the index fingertip is not a sensitive indicator of sensory decline, the minimum assessment of age-related changes in cutaneous sensation should include both hands, and sites on the palm.
