Abstract: Toiletry, Perfumery and Cosmetics Sector (TPCS) occupies a prominent place in modern society. The search for beauty and wellness, combined with increased life expectancy of the population, causes the intensive search to products that improve appearance, hygiene and health. Thus, the development of cosmetics is very stimulated. Another important feature is the continuously pressure from consumers and companies to this development of new and innovative products, raising competitiveness. Based on this, large sums are being annually invested in this area. Innovation is the world in cosm

Abstract:

Since the beginning of human cultivation, the role of plants in medicine has been of huge importance. The aim of this PhD Project is to investigate some forage plants belonging to the family of Fabaceae to gain knowledge concerning their possible use in nutraceutical, pharmaceutical and cosmetics field. These plants have been chosen because they are characterized by great productive potential, but they are still under-exploited from the officinal and industrial point of view. They are also a potential source for the extraction of bioactive compounds with possible pharmaceutical and cosmetic ap

Abstract:

In our modern society we are exposed to many natural and synthetic chemicals. The assessment of chemicals with regard to human safety is difficult but nevertheless of high importance. Beside clinical studies, which are restricted to potential pharmaceuticals only, most toxicity data relevant for regulatory decision-making are based on in vivo data. Due to the ban on animal testing of cosmetic ingredients in the European Union, alternative approaches, such as in vitro and in silico tests, have become more prevalent.

Abstract:

Plasticizers are generally added to cosmetic and personal care products to improve the filmforming abilities of the product and increase flexibility of the film formed on the skin or hair surface. For example, plasticizers are present in perfumes to prolong the release of the specific scent, which is the ultimate goal in a good quality perfume. Plasticizers in nail varnishes prevent chipping, improve the aesthetics by adhering to the keratin in the nail which means the coating stays on for much longer, which is the ultimate goal in nail products. Plasticizers improve the gloss, resist chipping

Appearance dissatisfaction and increased investment in appearance, or appearance orientation, have been linked to more favorable attitudes towards cosmetic surgery. Cognitive behavioral models of social anxiety were reviewed and integrated with existing theories of body image to provide a theoretical background for the exploration of influences on acceptance of cosmetic surgery. In this investigation, the relationships between subjective evaluations of appearance, appearance orientation (AO), fear of negative evaluation

Abstract:

Hyaluronic acid (HA) is an excellent biomaterial which thanks to its peculiar properties, such as biocompatibility, biodegradability, mucoadhesiveness, hydration and viscoelasticity is currently one of the most attractive polymers for many biomedical applications. Unfortunately, many of its potential applications are limited due to its short half-life as it is rapidly degraded by the hyaluronidase enzyme. In order to improve its half-life and consequently increase its performance, in this PhD thesis, native HA was modified through cross-linking reactions in which the polymer chains are stabili

A lipoaspiração da parede abdominal durante a abdominoplastia com descolamento amplo tem sido contraindicada devido ao aumento do risco de complicações. A lipoabdominoplastia realiza apenas o descolamento seletivo do retalho ao longo das bordas mediais dos músculos retos abdominais, preservando os vasos perfurantes abdominais, o que permite a realização, com maior seguranç

Sendo assim, é importante a utilização de um sistema antioxidante efetivo.

While currently the use of hot springs in Taiwan has not been fully explored, these facts give hot springs the merits for further study in cosmetic and m
