“…Therefore, clays are classified as natural inorganic rock or soil materials, composed of finely divided particles (inferior to 2 µm) with some plasticity while mixed with water and which hardens after drying. They are formed by clay minerals, organic matter, salt impurities, feldspars, and other minerals, like quartz, dolomite, calcite, iron, and/or aluminum oxides [5,6,13,14,17,[19][20][21]. It is applied to all small-sized particles found in soils or sediments including phyllosilicates, quartz, feldspars, carbonates, sulphates, iron and aluminum oxides, humus, and other mineral and/or organic components [6,13].…”

“…As actives, they are widely used for skin cleansing, oil reduction/control (skin and scalp), substance adsorption, antiaging, ultraviolet (UV) radiation protection (sunscreens), and ion exchange with skin, due to their color, qualitative and quantitative mineralogical composition, particle size and shape, structure, and ion exchange capacity. They can also be used in makeup products [2,[15][16][17][18].…”
The use of clays in beauty care comes from ancient times, with therapeutic use since prehistory, and it is considerably relevant in the current cosmetic industry worldwide. In our review, we described types of clay and clay minerals used in cosmetics and dermocosmetics, compositions, usages as active compounds and excipients, and observations about formulation techniques. From this research, we could notice that although many scientific and specialized literature reported the characterization of clays, only some involving efficacy tests when incorporated into cosmetic products, mainly concerning haircare applications. By the exposed, our review could be considered and encouraged in the coming years to provide scientific and technical information for the cosmetic industry regarding the multifunctional use of clays and clay minerals.

“…De acordo com Silva (2009), o estrato córneo é a camada mais superficial da epiderme, possui capacidade de evitar a perda de água e retê-la através dos corneócitos, devido a sua estrutura e composição mantendo assim a hidratação cutânea. A pele hidratada apresenta-se agradável ao toque, porém a pele seca encontra-se descamativa, irregular e espessa.…”

“…xerose ocorre pelo desarranjo das funções e sustentação da epiderme, promovida pela umidade e temperatura, exposição a produtos químicos e falta de adequação a produtos cosméticos. A conservação da hidratação cutânea e a renovação celular atuam de maneira convincente na estabilidade da saúde, elasticidade, maciez e jovialidade cutânea (Silva, 2009 Disponível em: <https://agenciadenoticias.ibge.gov.br/agencia-noticias/2012-agenciadenoticias/noticias/18469-expectativa-de-vida-do-brasileiro-sobe-para-75-8-anos>.

Introduction: According to the Brazilian Association of Sleep Medicine, the activities of the present day have hampered the quality and time of sleep, causing damage to the Central Nervous System and releasing substances directly related to stress, thus the metabolism changes in the absence of a few hours of sleep by night they were equated with that of an old man. Objective: To verify the influence of classic (relaxing) body massage associated with atherapy in sleep quality and stress in university teachers. Methodology: An exploratory and qualitative study was carried out, with a sample of 14 university teachers, through questionnaires and massage practices with association of the essential oils of Olíbano and Cedro, controlled the results with oximeter and Power Lab. Results: Although there was no difference it is worth noting that cedar oil reduced in a manner considered the Heart Rate of the volunteers. All volunteers reported that there was improvement in sleep quality regarding the night of the day of receiving the massage, such as decreased pain, constant sleep at night, leading us to confirm the great effect that relaxing massage exerts on the individual. Conclusion: Although the inhalation results of essential oils have not given statistical differences, we can conclude that this procedure is effective in improving stress and gradually improving the quality of sleep.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
