ABSTRACT
Objectives: To study the effect of astaxanthin contained drink to skin conditionMethod: The study was conducted to the Japanese females between age over thirty to less than fifty , who had weakening of skin (including aging, sag and dry skin) and skin dullness. In order to conduct the objective evaluation, the comparison between the groups by the double-blind test was taken. Twenty of subjects were randomly allocated to the intake group of astaxanthin contained drink (astaxanthin 3mg contained) and the placebo group. After eight weeks intake of the drink, each group was evaluated with skin water contents, transepidermal water loss, skin elasticity, VISIA and skin texture etc.Result: In between the groups, the intake group of astaxanthin contained drink was greatly excellent in the categories of skin moisture, transepidermal water loss, skin elasticity , erythema dose and skin texture.Conclusion:Astaxanthin has protecting effect of skin barrier and is considered to increase the water retention capability to reduce skin dryness. Astaxanthin is also effective to erythema dose, skin elasticity and skin texture. As no adverse events resulting from the test drink was seen, such food containing astaxanthin is considered as a safe and useful health functional food material to skin.
ABSTRACT
In recent years, because the dry skin problem has become very common, it is getting the more important to preserve the barrier function of the skin. Although protecting the skin against water loss is one of the representative factors of its barrier capabilities, there is no report until now about the relationship between daily use of bath liquid and the moisture-keeping capacity of the skin.<BR> In this study we examined how the skin condition can be improved after 14 straight days of employment of our bath liquid ‘Ulmore<SUP>®</SUP>’including Polyquaternium-10 and several moisturizing ingredients. Polyquaternium-10 is a Cationized Cellulose and is widely formulated in shampoos and hair conditioners.<BR> We found that the application of Ulmore<SUP>®</SUP> for 10 or 14 days significantly maintained sratum corneum water content (SCWC) and transepidermal water loss (TEWL) compared with the placebo application. This result suggests that this is because our bath liquid covered the stratum corneum and protected the skin from water loss caused by the environmental factors like low humidity.<BR> Thus we conclude that daily use of the bath liquid has a beneficial effect on skin moisture.

In this study we examined how the skin condition can be improved after 14 straight days of employment of our bath liquid ‘Ulmore®’including Polyquaternium-10 and several moisturizing ingredients. Polyquaternium-10 is a Cationized Cellulose and is widely formulated in shampoos and hair conditioners. We found that the application of Ulmore® for 10 or 14 days significantly maintained sratum corneum water content (SCWC) and transepidermal water loss (TEWL) compared with the placebo application. This result suggests that this is because our bath liquid covered the stratum corneum and protected the skin from water loss caused by the environmental factors like low humidity. Thus we conclude that daily use of the bath liquid has a beneficial effect on skin moisture.
ABSTRACT
The purpose of this study was to investigate the effects of dietary habits and nutrient intakes on skin condition of female university students. The subjects were 95 female university students in Daegu. This study examined anthropometric measurements, dietary intake, food intake habits and skin condition (moisture, elasticity, sebum (U-zone, T-zone), pores, evenness and melanin pigmentation. The subjects in this study had an average age of 21.4, an average height and weight of 161.2 cm and 52.9 kg, respectively, and the average body mass index (BMI) was 20.3 kg/m2. The means of skin elasticity, pores, evenness, and melanin pigmentation were within the normal range of women in their 20s and the skin moisture state was slightly lower than the normal range, which showed a dry tendency. The sebum in the U-zone and the T-zone was lower than the standard values, which showed less secretion in both areas. The subjects with high nut intake showed a better skin pore state (p < 0.05). Those with a high intake of instant foods showed a sig-nificantly low skin moisture and a significantly higher sebum rate (p < 0.05). The group with high skin elasticity and the group with less melanin pigmentation showed a significantly low animal protein intake (p < 0.05). The group with high skin elasticity also showed a significantly higher vitamin A and niacin intakes as well (p < 0.05). The group with high skin evenness showed a significantly lower animal lipid intake and a significantly higher vitamin E intake (p < 0.05). In addition, those with high skin elasticity and evenness as well as low melanin pigmentation showed a tendency of high intake of antioxidant vitamins, such as vitamin A, carotene, vitamin C or vitamin E. In summary, a moderate intake of plant-based products and also the antioxidant vitamins within such products seems to have a beneficial effect on maintaining a healthy and good skin condition.

[Purpose] In Kampo medicine, blood deficiency is considered to cause systemic symptoms such as insomnia and dizziness, in addition to skin-related symptoms such as xeroderma. Diagnosis of blood deficiency does not appear to be definitive since it is based on subjective judgment. To resolve this problem, we have attempted to establish an objective method for diagnosing blood deficiency by measuring skin moisture.[Methods] Using a skin moisture meter, we measured the skin moisture (at the neck, forearm, and abdomen) of 80 women during their first examination at our clinic. The patients were also classified according to their blood deficiency scores.[Results] A statistically significant difference was observed between patients with blood deficiency and those without blood deficiency with regard to the skin moisture at the neck and forearm. The coefficient of correlation between the skin moisture of the neck and the blood deficiency score was -0.41.The results of statistical analysis performed using a type1quantification method revealed high values even for some conditions not associated with the skin, such as hypomenorrhea and excessive strain of the abdominal muscles, in addition to high values for skin-associated conditions. And in pre-post-treatment comparisons, improvements in blood deficiency scores generally matched transitions in keratinous moisture.[Discussion] Due to the absence of a high correlation between skin moisture and the blood deficiency score, it is unlikely that skin moisture can be used instead of the blood deficiency score as a parameter for the accurate diagnosis of blood deficiency.[Conclusion] Although skin moisture levels may be an indicator of blood deficiency, further studies are required before this parameter can be applied in clinical diagnosis.

We conducted a preliminary study of the facial skin-improving effects of collagen-containing beverages as evaluated by objective indices. After obtaining written informed consent, 61 healthy females (age: 25–68, 34±8 y.o.) were randomly divided into two groups, receiving beverages containing 5 g (N=30) and 10 g (N=31), respectively, of collagen daily for one month. Facial skin moisture content and lower eyelid wrinkles were assessed before, 1 week and 1 month after consuming the test beverages. Results were analyzed of the 5 g and 10 g groups, as well as responder and non-responder groups. 10 g collagen beverages showed 50% effectiveness, and were more effective than the 5 g beverage; the effect was observable within 1 week. Furthermore, subjects with more wrinkles and drier skin showed greater benefit than those with higher facial skin moisture content and/or fewer wrinkles. It is suggested that a beverage containing 10 g collagen should be used for aged subjects with more wrinkles and/or drier skin for a period of 1–2 months in future randomized placebo-controlled trials of collagen-containing beverages.<br>
ABSTRACT
Objects : The purpose of this study is to evaluate objective measurements of skin moisture and its usefulness in the Kampo clinic.Methods : We measured the skin moisture of 6 male volunteers using a sensor twice, in a one to two week interval, and calculated the correlation of both data sets at 66 points. Secondly, we compared the skin moisture data at 10 regions in 81 patients without any skin disease, in a wide age range from 30 s to early 70 s. The ten regions measured were : face, chest, back, abdomen, leg and 4 forearm points, i.e. the inside and outside of the bilateral center forearm, and palm.Results : The correlation of two successively measured data sets showed excellent relation (r=0.716, p<0.0001). The sensor measurement of skin moisture was quite reliable. Measurements of the face, chest and back showed them to be significantly wetter than the abdomen, leg or any of the 4 forearm points. Palm measurements indicated a wetter tendency than for any forearm measurements. Back and abdomen measurements in males were significantly wetter than those in females. There were no significant differences among the data sets, with regards to age. Therefore, any forearm points are clinically useful for the standard measurement of skin moisture. We also demonstrated a case in which skin moisture measurements with a sensor were useful in prescribing and observing the effects of shigyakusan.Conclusion : Utilizing this method may be helpful in acquiring much more objective measurements for Kampo medicine.
