In the study, we report the comparative efficacy of the sodium hyaluronate gel vaginal application and promestriene cream which were tested to treat the gynecological symptoms of people who suffered from vaginal dryness. Method: 35 patients applied sodium hyaluronate vaginal gel one time a day for a period of two times a week during three weeks and other 33 patients using promestriene cream applied it every day for a period of three weeks also. Results: No significant difference was observed between vaginal application of sodium hyaluronate gel and promestriene cream, regarding both, as regarding the dryness of the intimate mucosa (p = 0.786), the attribute of moisturizing properties to the intimate mucosa (p = 0.142), the comfort sensation (p = 0.528), and no significant difference was observed regarding the fragrance of the product (p = 0.088). Conclusion: The similar results between vaginal application of both products support the use of sodium hyaluronate vaginal gel (Lubrinat®) in the initial approach of symptoms of vaginal dryness.
Before marketing a cosmetic product, a series of biological assays, such as ocular irritation tests, must be conducted in order to prove that the product is safe. However, a few scientific articles mention the discussion and evolution of cosmetic products testing performed in the eyes area. The aim of this study was to review the available literature on the evolution of tests carried out with cosmetics, in the ocular area, as well as to describe the methodologies that have been used and that are currently accepted. In Brazil, tests performed on animals are still allowed. However, the international laws strongly recommend the use of alternative methods for evaluating the risk of cosmetic ingredients and products. Regulatory requirements involving the registration of these products also request safety support of them in human beings. To perform ocular tests in human beings, it is necessary to involve an ophthalmologist for conducting clinical protocols. These protocols signed by the expert physician are sent to the National Health Surveillance Agency in order to endorse the product manufacturer concerning its safety. The safety support of a cosmetic product is very important, taking into account that the consumer has free access to these products of widespread use in today's society.Uniterms: Eyes/cosmetics use. Cosmetics/safety assessment. Ocular irritation/tests. Ocular area/safety use of cosmetics Com o objetivo de comprovar que um produto cosmético é seguro, antes que este seja colocado no mercado, este deve passar por uma série de ensaios biológicos, que avaliem sua segurança, como, por exemplo, os testes de irritação ocular. Porém, poucos artigos científicos trazem a discussão e a evolução sobre os testes de produtos cosméticos realizados na área dos olhos. O objetivo desse trabalho foi realizar uma revisão bibliográfica sobre a evolução dos testes realizados com cosméticos, na região ocular, bem como descrever as metodologias que já foram utilizadas e as que são aceitas atualmente. No Brasil, são ainda permitidos testes em animais, entretanto, as legislações internacionais indicam fortemente a utilização de métodos alternativos para avaliação de risco de ingredientes e produtos cosméticos. As exigências regulatórias que envolvem o registro desses produtos solicitam também a comprovação de segurança destes produtos em serem humanos. Para a realização dos testes oculares em humanos, é necessário o envolvimento de um oftalmologista na condução de protocolos clínicos. Esses protocolos assinados pelo médico especialista são enviados à Agencia Nacional de Vigilância Sanitária, a fim de respaldar o fabricante do produto sobre a segurança do mesmo. A comprovação da segurança de um produto cosmético é bastante importante, considerando-se o livre acesso aos consumidores e o amplo uso desses produtos na sociedade atual.
