[The benefits of socio-aesthetics in psychiatry: three experiments with adolescents].

Adolescents and young adults admitted to the Espace unit at Nantes University Hospital are offered beauty treatments. Although their situations are diverse, they consistently show a decline in self-esteem. These young patients benefit from individual hand and facial treatments, make-up sessions and group workshops.

Feedback on a socio-aesthetic program for the benefit of young patients with self-endangerment.

Objectives: Socio-aesthetics is a practice born in psychiatric departments but has since developed particularly in the field of oncology. For our part, since January 2018, we have initiated an experiment of this type at the Espace Unit of the CHU in Nantes, a unit that takes care of young patients who find themselves in a situation of crisis and endangerment of themselves.

Methods: The qualitative evaluation of the interest of a socio-aesthetic mediation (relaxation modelling, facial care, make-up) with young patients was carried out by a collection of their feelings.

Per- and polyfluoroalkyls used as cosmetic ingredients - Qualitative study of 765 cosmetic products.

Per- and polyfluoroalkyl substances (PFAS) form a vast family comprising more than 4700 synthetic compounds. Their molecules contain a terminal functional group and a hydrophobic carbon tail (alkyl group) at which the hydrogen atoms are totally (in the case of perfluorinated compounds) or partially (in the case of polyfluorinated compounds) replaced by fluorine atoms. Due to the very specific properties of their structure, they have been used in a vast range of applications over the last 70 years.

An Eco-Friendly Extraction and Purification Approach for Obtaining Active Ingredients for Cosmetics from Two Marine Brown Seaweeds.

Brown seaweeds are attracting attention due to their richness in bioactive compounds, in particular, their phlorotannins. We present here a case study of two Fucales, and , sustainably collected, to produce active polyphenols for the cosmetics sector. Phenolic contents of crude extracts, obtained by Accelerated Solvent Extraction (ASE), were more elevated in at 100.

A review of homemade cosmetics based on a study of 150 blogs and their authors.

Do-it-yourself methods have been used in many fields (cooking, home improvement, decoration, gardening, etc.) for a long time, but their application to the cosmetics sector is relatively recent and seems to be linked to a number of health scandals. The objective of this work is to analyse homemade cosmetics based on a study of blogs and their authors.

The Role of Essential Oils in Homemade Cosmetics: A Study of 140 Recipes.

Two recent trends that have developed simultaneously are a mistrust of health products by some of the population and the growing popularity of essential oils. The objective of this study was to analyze recipes with essential oils found on the internet and to assess their level of photoprotective efficacy. Therefore, we conducted a study of 140 recipes for personal care and hygiene products that incorporate one or more essential oils.

Analysis of 275 DIY recipes for eye cosmetics and their possible safety issues.

Some consumers have become very suspicious of certain health products such as medicines, medical devices and cosmetics. This can lead them to choose to make such products themselves. The aim of this work was therefore to analyse recipes for eye makeup and makeup removal products, as well as eyelash and eye contour care products.

[History of socio-esthetics].

Concerns about physical appearance and the image projected to others have always existed. Physical difference socially generates stigmatising behaviour, of which women are the first victims. The idea of repairing the body is at the basis of the development of aesthetic care.

A study of 84 homemade toothpaste recipes and the problems arising from the type of product.

Objective Growing consumer mistrust of a number of ingredients used in industry has led to the development of a trend for homemade products. This now affects all types of sectors, but particularly the hygiene sector for shampoo and toothpaste products. The aim of this work is therefore to study recipes found on the internet for these types of products in order to assess risks associated with their use.

What level of photoprotection can be obtained using facial mask? Determining effectiveness using an in vitro method.

It has become a general practice worldwide to wear a face mask serving as a barrier against the transmission of pathogens. This has prompted us to investigate whether masks could also protect our skin from UV radiation. We have studied eight masks, four surgical and four "homemade" using an in vitro method.

Demonstration of the dangerous nature of 'homemade' sunscreen recipes.

Background: Following a growing mistrust in a certain number of ingredients used by the cosmetic industry, it has become popular in recent years for consumers to make their own products at home. This trend now touches on all areas of the industry, but is especially found in the hygiene sector, with shampoos and toothpaste, and the care sector, with moisturizers and sunscreen, products.

Objectives: The objective of this study is to analyze sunscreen recipes found on the Internet and to assess their level of photoprotective efficacy.

Phycocosmetics and Other Marine Cosmetics, Specific Cosmetics Formulated Using Marine Resources.

Marine resources exist in vast numbers and show enormous diversity. As a result, there are likely many possible applications for marine molecules of interest in the cosmetic industry, whether as excipients or additives, but especially as active substances. It is possible to obtain extracts from active substances; for example, quite a few algae species can be used in moisturizing or anti-ageing products.

Study of the composition of 140 shampoos: similarities and differences depending on the sales channel used.

Shampoo is a hair care product designed to clean the skin and hair of the scalp. Among the ingredients that go into the making of a shampoo are detergents, conditioners, thickeners, sequestering agents, pH adjusters, preservatives, and active ingredients such as anti-dandruff agents. The purpose of this study was to identify the composition of 140 shampoos available in pharmacies, in stores of a mass-market chain, or from mail-order retailers.

Evaluation of Different Colorless Nail Polishes Used as Supportive Care in Patients with Cancer in Terms of Photoprotective Efficacy and Water Resistance.

In patients undergoing chemotherapy, the application of nail polish and/or a colorless base coat is recommended in order to prevent the adverse effects that can occur on the nails throughout treatment. In this study, the photoprotective effects of different clear nail polishes were examined. Twelve commercially available, colorless nail products were tested .

[Comparison of different nail polish in terms of photoprotective efficacy. Interest of their use as supportive care in patients with cancer].

Many different chemotherapy drugs including cytotoxics and docetaxel in particular are responsible for side effects involving the nails. To prevent these negative effects, patients are advised to apply nail polish. The aim of this article is to study the photoprotective effect of various products applied in two layers.

Structural elucidation, in vitro antioxidant and photoprotective capacities of a purified polyphenolic-enriched fraction from a saltmarsh plant.

In temperate saltmarshes, halophytic plants have to daily protect their internal tissues against sunlight and UV rays. Consequently, they develop adaptive responses such as the synthesis of secondary metabolites, including polyphenols. The present study focused on the biological activities of fractions enriched in polyphenols from Salicornia ramosissima.

Research on the immunosuppressive activity of ingredients contained in sunscreens.

The immunosuppressive properties of Benzophenone-4, an UV-filter and three ingredients, Allantoin, Bisabolol and Enoxolon used in sunscreen formulation, previously characterized as anti-inflammatory compounds, are studied. The results of this study demonstrate that four tested molecules have effects on DCs and T cells which are the most important cells of the immune system. The impact is also visible on keratinocyte cells which are in the direct contact with skin sunscreens.

BB creams and their photoprotective effect.

BB creams appeared on the market quite recently. These creams, which give a perfect complexion by covering up the skin's blemishes, have a photoprotective effect in the majority of cases. An SPF value ranging from 10 to 45 concerning the products we tested is displayed on the packaging.

Marennine, promising blue pigments from a widespread Haslea diatom species complex.

In diatoms, the main photosynthetic pigments are chlorophylls a and c, fucoxanthin, diadinoxanthin and diatoxanthin. The marine pennate diatom Haslea ostrearia has long been known for producing, in addition to these generic pigments, a water-soluble blue pigment, marennine. This pigment, responsible for the greening of oysters in western France, presents different biological activities: allelopathic, antioxidant, antibacterial, antiviral, and growth-inhibiting.

Lichenic extracts and metabolites as UV filters.

Three lichen extracts and ten lichenic compounds have been screened for their photoprotective activities. The determination of their Sun Protection Factor (SPF) and Protection Factor-UVA (PF-UVA) values was done in vitro. Among them, a Lasallia pustulata extract and gyrophoric acid exhibited SPF values over 5, which is better than Homosalate (SPF≈4).

UV filters, ingredients with a recognized anti-inflammatory effect.

Background: To explain observed differences during SPF determination using either an in vivo or in vitro method, we hypothesized on the presence of ingredients having anti-inflammatory properties.

Methodology/principal Findings: To research our hypothesis, we studied the 21 UV filters both available on the market and authorized by European regulations and subjected these filters to the phorbol-myristate-acetate test using mice. We then catalogued the 13 filters demonstrating a significant anti-inflammatory effect with edema inhibition percentages of more than 70%.

Influence of certain ingredients on the SPF determined in vivo.

When determined in vitro, the SPF of certain commercial sunscreen products can be lower than the SPF indicated on the label. The study of the composition of this type of product enabled us to note that the majority contained substances reputed to have anti-inflammatory properties. This effect is shown by inhibiting the erythema, without protecting the skin, which constitutes a serious public health problem.
