    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

    15 Jun War on the full wax

    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.

    Can diet improve acne?

    10 Jun Can diet improve acne?

    Acne is an extremely common disorder of the skin that affects 85% of people between the ages of 12 and 24 years. Except in the most severe cases, acne is considered to be a simple physiological alteration, yet it can greatly affect quality of life. The influence of diet on acne is still being debated today.

     

    Acne is a disorder of the hair follicles, with many influencing factors: increased sebum (oil) production stimulated by hormonal factors; pore blockage due to increased cornification; and finally, proliferation of the bacterium Propionibacterium acnes. The result is an inflammatory response and the formation of the lesions characteristic of acne, whether pimples, papules, pustules (pimples with pus) or, in more severe cases, nodules, cysts and scars.

    The piercing queen

    In this blog dedicated to caring for the skin, we cannot condone piercings for the simple reason that they are a direct assault on our skin. Furthermore, piercings can and do cause infections and serious health complications. But some people seem to defy the statistics. This is the case of Elaine Davidson, who has survived with over 9,000 piercings!

     

    The Guinness Book of Records has recorded the case of this Brazilian woman as the undisputed champion of skin piercings. In 2000 she had 462 piercings, 192 in her face alone. By 2012 she had over 9,000 – with more in the genital area than anywhere else, she says. It is estimated that all this internal and external decoration weighs over three kilos. Ms. Davidson, who does not drink or take drugs, runs an aromatherapy shop in Edinburgh, where she lives with her husband, Douglas Watson, who – to compensate, we suppose! – does not have a single piercing in his entire body. Our post merely documents this curious penchant – we do not recommend following this woman’s example. Just bear in mind that 30% of piercings cause complications and 15% require a visit to the doctor. (Photograph: Janek Mann, Creative Commons licence).
