Acne vulgaris and the most popular and new cosmetological treatments
2023
Introduction: Acne vulgaris is a disease that has an enormous impact on appearance of the skin of the patients and also on their quality of life. Long-term dermatological treatment, which often lasts years, and disease relapses contribute to the occurrence of low self-esteem and depression. Acne is one of the 10 most common diseases in the world and the most common inflammatory skin disease. Many methods of dermatological treatment that bring very good results are available. However, educating people with acne on how to take care of their skin on a daily basis to minimize the bleak effects of the disease is an extremely important element. Contemporary cosmetology creates an environment for …
Efectos de las consultas boca a boca en redes sociales en la compra de cosméticos en Ecuador.
2022
Las redes sociales han reestructurado el paradigma de la comunicación en el marketing. Investigaciones recientes demuestran que la conducta de consultar reseñas está adquiriendo un rol fundamental en la decisión de compra de los consumidores. En este contexto, el presente estudio desarrolló un marco de investigación para determinar la cadena de relación entre influencia social, credibilidad percibida del boca a boca, adopción del boca a boca e intención de compra aplicada a la industria cosmética del Ecuador. A través de una muestra de 406 consumidores y la aplicación del método de análisis de ecuaciones estructurales, los resultados evidencian el vínculo existente entre las variables plant…

Microneedling dilates the follicular infundibulum and increases transfollicular absorption of liposomal sepia melanin
2015
Gabriel Serrano,1 Patricia Almudéver,2 Juan M Serrano,3 Julio Cortijo,2 Carmen Faus,1 Magda Reyes,1 Inmaculada Expósito,3 Ana Torrens,3 Fernando Millán1 1Clínica Dermatológica Serrano, 2Department of Pharmacology, University of Valencia, 3Research and Development Department, Sesderma Laboratories, Valencia, Spain Abstract: Encapsulation of chemicals in liposomes and microneedling are currently used techniques to enhance the penetration of several substances through skin and hair. In this study, we apply a liposomal melanin–fluorescein compound to an ex vivo model of human skin, using a new electrical microneedling device (Nano…
Application of the threshold of toxicological concern (TTC) to the safety evaluation of cosmetic ingredients.
2007
The threshold of toxicological concern (TTC) has been used for the safety assessment of packaging migrants and flavouring agents that occur in food. The approach compares the estimated oral intake with a TTC value derived from chronic oral toxicity data for structurally-related compounds. Application of the TTC approach to cosmetic ingredients and impurities requires consideration of whether route-dependent differences in first-pass metabolism could affect the applicability of TTC values derived from oral data to the topical route. The physicochemical characteristics of the chemical and the pattern of cosmetic use would affect the long-term average internal dose that is compared with the re…
Hair Dyes in Cosmetics. Regulatory Aspects and Analytical Methods
2007
Abstract Fragrance ingredients are extensively used in perfumes and other cosmetics, providing us with a pleasant scent. However, different fragrance chemicals and other chemicals present in perfume composition have been shown to cause undesirable side effects. The EC Regulation prohibits and limits the contents of some of them in cosmetics. Other international organizations, such as the International Fragrance Association and the Research Institute for Fragrance Materials, work on the safety of fragrance chemicals and release reports on the convenience or not of using certain fragrance chemicals in cosmetics, depending on their toxicity. This chapter is focussed on the determination of fra…
Essential Oils
2016
Abstract Essential oils are aromatic, volatile liquids obtained from plant material through steam distillation and named after the plant from which they are derived. Essential oils can be defined as either products or mixtures of fragrant substances or as mixtures of fragrant and odorless substances. These fragrant substances are chemically pure compounds that are volatile under normal conditions. Essential oils vary greatly, sometimes due to genetic causes, but also because of climate, rainfall, or geographic origin. They are composed principally of lipophilic and highly volatile secondary plant metabolites, principally mono- and sesquiterpenes, but other types of compounds such as allyl a…
Therapeutic use of hyaluronic acid fillers in the treatment of corticosteroid-induced skin and subcutaneous atrophy
2016
Corticosteroid injection–related tissue atrophy might cause permanent skin and soft tissue deformities1 due to several factors, most importantly fibroblast inhibition and decreased Type I collagen synthesis. Correction of these deformities is challenging and is mostly based on volume replacement with lipofilling or other methods. Clinical observations and research have shown that injection of stabilized hyaluronic acid (HA) induces collagen synthesis, partially restoring dermal matrix components, and eventually producing a permanent effect.2–5 Based on these data, we hypothesize that HA injections might successfully treat atrophic tissue changes caused by corticosteroid injection. We descri…
Complications of botulinum toxin and fillers: A narrative review
2019
Background Cosmetic surgery and esthetic procedures have become a billion dollar industry owing to the ever-growing demand of the population to stay young. The injectable treatments including fillers and botulinum toxin have become highly popular because of their quick, predictable and lasting results in the management of facial wrinkles and rejuvenation. Although these treatment modalities are relatively safe, they are associated with certain side effects. Aims In this review, we will focus on the complications of fillers and botulinum toxin. Patients/methods The literature research considered published journal articles (clinical trials or scientific reviews). Studies were identified by se…
Reflecting on Female Beauty: Cosmetic Surgery and (Dis)Empowerment
2018
This project aims to unwrap some of the complexities related to female beauty and the body. It reflects on the second wave radical feminist view that beautifying the female body serves to attract male approval via the male gaze, both of which are deeply entrenched in patriarchal power. This perspective positions cosmetic surgery as a disempowering act for women. In riposte, we turn to third wave liberal feminist ideas to engage with the narratives of ten participants who tell of their personal experiences of, and motivations for, undergoing a cosmetic intervention. We undertake an in-depth exploration of these lifeworld experiences and the interplay of subjectivity and intersubjectivity in …
