    10 tips for healthy, strong and beautiful nails

    10 Jul 10 tips for healthy, strong and beautiful nails




    Our fingernails play a key protective role and are also aesthetically important. They protect our fingertips – our main source of tactile information – and enable us to grasp and manipulate all sorts of objects. They are also a window to general health problems. These tips will help you keep your nails healthy and beautiful.


    1. Keep nails always clean and dry. Nails can easily become an ideal home for bacteria and fungi. For this reason, you should keep them clean, avoid leaving your hands too long in water and wear rubber gloves when cleaning or when handling chemicals.


    2. Don’t abuse your nails. Nails, like hair, are made of keratin and are an integral part of the skin. They are constantly in touch with the environment and easily damaged. When you use them as a tool to scratch things or manipulate objects, do so carefully. And when you decorate them, learn the facts about the risks associated with different techniques. Read More

    Allergens in cosmetic products

    We have known of skin allergic reactions associated with cosmetic products for many years. And each year, hundreds of studies add further information about the safety of ingredients. As a result, new regulations and limitations on use are constantly emerging. Which ingredients are the most allergenic?


    Health authorities have published numerous lists of ingredients whose allergenic potential is known. But as well as considering an ingredient’s facility for eliciting an immune reaction, we also need to consider its frequency of contact with the skin and mucous membranes. Both these factors – allergenic potential and application frequency – are the triggers for most cases of undesirable reactions produced by the use of cosmetic products. Read More

    War on the full wax

    Mail Online

    The actress Cameron Díaz has recently argued in favour of pubic hair and American Apparel storefronts have rekindled the debate. Is it advisable to remove all hair from the genital area? Is it more hygienic to shave your privates — or the reverse?


    Genital hair removal was a standard practice in ancient Greece and Roman public baths even had specific depilation rooms. And not so long ago, a number of gynaecologists were arguing that shaving your privates was more practical in terms of treating infections. But there has been an about turn, at least from a medical standpoint. Many hospitals now rule out hair removal, including for childbirth. What’s more, the Spanish Association of Dermatology and Venereology (AEDV) is of the opinion that full genital waxing is an "absurd fashion" that leads to an increase in sexually transmitted diseases.
