BACKGROUND: The impact of a chronic outdoor urban pollution on skin aging-related facial signs is a poorly referenced topic. OBJECTIVE: To assess, through visual grading and referential photographic atlas, possible differences in some facial signs between Chinese women, of comparable ages, living in two close cities very differently exposed to urban pollution. METHODS: The faces of 2 cohorts of 204 Chinese women (2 x 102) of same age-groups (25-45 y), living in Baoding (a highly polluted city) and Dalian (a less polluted city), for at least 15 years, have been analyzed...

BACKGROUND: Hyaluronic acid (HA) has been considered the gold standard ingredient for improving skin hydration and combating age-related effects, however it is an inefficient polymer with inconsistent results partially due to its poor skin penetration, surface deposition, and rapid degradation. Herein we report the synthesis and in vitro characterization of a newly developed, topical super-humectant with the goal of attracting and binding water molecules more efficiently than traditional, cosmetic-grade forms of HA...

We evaluated the friction properties of five cosmetic sponges on artificial skin using sinusoidal motion-friction evaluation system. No significant difference was observed in the pleasant score of the five sponges when these sponges were rubbed on the skin surface. The sponges were classified into three groups based on their tactile feel. Their characteristic tactile textures were moist-soft-slippery, moist-dry-rough, and moist feels. The slippery feel was found to depend on the thickness of the sponge's cell wall, its surface tension, and the change in friction coefficient in the dynamic friction process...

Angelica tenuissima root has historically been used as a traditional medicine in Korea. Previous studies have identified the anti-melanogenic effects of the extract of A. tenuissima root fermented by Aspergillus oryzae (FAT). This study investigated the protective effects of FAT against ultraviolet light B exposure (UVB; 30 mJ/cm2 ) in HaCaT (human keratinocyte) or Hs68 (human foreskin fibroblast) skin cells. FAT treatment was able to stimulate wound healing rate at the basal condition. FAT also favored the maintenance and/or improvement of extracellular matrix impairment caused by UVB irradiation through: 1) upregulation of procollagen Type-1 synthesis and secretion; 2) suppression of MMP-1 and elastase expression...

Application of exogenous products, such as creams, to the skin can result in subclinical changes in selected epidermal functions such as transepidermal water loss (TEWL), hydration, redness, and pH; these changes may lead to or contribute to irritation. Changes in skin surface inflammatory factors may provide further insight into this potential for irritation. The objective of this study was to evaluate the changes in epidermal properties and inflammatory mediators after 4 days of topical application of 2 different polymers formulated in cosmetic creams...

Calreticulin is an endoplasmic reticulum-resident, calcium-binding, stress-produced, chaperone protein that serves multiple functions and is widely distributed in eukaryotic cells. Exogenously applied recombinant calreticulin solution, markedly enhanced the rate and quality of skin wound healing. These modulatory effects are more efficient than commercially available topic platelet-derived growth factor ointments (Regranex® ). Trypanosoma cruzi calreticulin is more effective in equimolar terms to human counterpart in accelerating skin wound healing...

Background: Buttock augmentation with fat transfer has become increasingly popular, with many patients seek high-volume augmentations. There is a lack of consensus as to the safe upper-limit of fat that can be transferred. Concern for risks such as fat necrosis and fat embolism may lead surgeons to limit the amount of fat to place. However, it is unclear if volume alone is associated with these complications. The authors examined their experience to evaluate the outcomes of high-volume fat transfer...

TiO2 is a common inorganic filter used in sunscreens due to its photoprotective effect on the skin against UV radiation. However, the use of this kind of material in cosmetics is limited by its inherent photocatalytic activity. It is known that coating on TiO2 surface can improve some features. Although, many of the methodologies used for this purpose are still laborious and time-consuming. Thus, this work reports a novel, easy, cheap and fast strategy to coat TiO2 particles by using a sonochemistry approach, aiming to decrease photocatalytic activity and to enhance colloidal stability...

Pediatric chest wall tumors are rare. Malignancies predominate of which sarcomas are the most common. Their resection and the subsequent reconstruction of the chest wall has been a surgical challenge since Dr. Frederick W. Parham published his first comprehensive account on the subject in 1898. Chest wall reconstruction is age, site and pathology dependent, must preserve long term function and cosmesis, must accommodate future growth and development, and must not be a hindrance to adjuvant radiotherapy. Bony reconstruction can be relatively simple or complex involving combinations of synthetic meshes, bioprosthetic materials, steel or titanium constructs, autografts, homografts and porcine or bovine xenografts...
