In this paper, the formation of liquid crystal structure in preparation of emulsion and the change of those liquid crystal structures during storage and usage were studied. Besides, the rheological and moisturizing property of the liquid crystal structure emulsion was investigated as well. The results show that the liquid crystal structure at oil-water interface in the emulsion forms gradually ...

Taking an alcohol swab of a person's forearm and analyzing it using a spectrophotometer has been shown to be a reliable method for detecting the presence of sunscreen. The aims of this study were to determine if moisturizing lotions or other non-sunscreen products influence the absorbance readings from skin swabs in a controlled setting, and to establish the cutoff point in determining the pres...

The recognition that ultraviolet radiation has harmful effects on the skin has led to the commercial development of inorganic and synthetic organic UV filters that can reduce the negative effects of exposure to sunlight. In addition, moisturizing chemicals are extensively used in personal care products to improve the ability of skin to retain water. Whilst current UV filter and moisturizing che...

Epidermal filaggrin level is affected by ultraviolet B irradiation in animal and experimental models. This study examined the effect of ultraviolet B irradiation on epidermal filaggrin and natural moisturizing factors in vivo in healthy adults (n = 22). Participants were irradiated with 2 minimal erythema doses of ultraviolet B on the skin. Biopsies and tape strips were collected from skin irra...

Itch is frequently associated with dermatoses characterized by a defective skin barrier. We formulated an itch-relieving moisturizing cream containing 3% menthol and ceramides. Our aim was to evaluate the safety and antipruritic efficacy of application of this cream in volunteers with and without skin diseases. Volunteers were asked to apply the cream for 1 month on a minimum body surface area ...

Hyaluronan (HA) is present in many tissues of the body and is essential to maintain moistness in the skin tissues, which contain approximately half the body's HA mass. Due to its viscosity and moisturizing effect, HA is widely distributed as a medicine, cosmetic, food, and, recently marketed in Japan as a popular dietary supplement to promote skin moisture. In a randomized, double-blind, placeb...

Glycolipid biosurfactants, such as mannosylerythritol lipids (MELs), are produced by different yeasts belonging to the genus Pseudozyma and have been attracting much attention as new cosmetic ingredients owing to their unique liquid-crystal-forming and moisturizing properties. In this study, the effects of different MEL derivatives on the skin were evaluated in detail using a three-dimensional ...

Patients with atopic skin show a defective barrier function both in rough and in clinically normal skin, with an increasing risk of developing contact dermatitis. Moisturizing creams are often used in the treatment of dry skin. The purpose of this study was to investigate the influence of treatment with a urea-containing moisturizer on the barrier properties of atopic skin. Fifteen patients wit...

Background: The stingless bee is a natural type of bee that exists in almost every continent. The honey produced by this bee has been widely used across time and space. The distinctive feature of this honey is that it is stored naturally in the pot (cerumen), thus contributing to its beneficial properties, especially in the wound healing process. Methods: In this article, several studies on sti...

Background/Purpose: Phimosis, owing to the presence of a preputial fibrotic ring, is surgically treated in 1% of children. During the last decade, however, topical steroid treatment has been proposed for phimosis. Methods: We present a double-blind study comparing 0.1% mometasone furoate topical cream vs moisturizing cream (placebo) for the treatment of phimosis. Children aged from 2 to 13 year...
