Psoriasis is a chronic condition which predominantly affects the skin and develops in about 2% of the population. Its psychological impact is great as it sometimes leads to social rejection, mainly due to other people’s ignorance of the disorder.
Psoriasis is a chronic inflammatory disorder that affects the skin, nails and sometimes the joints. Around 2% of the population is affected. Psoriasis is caused by defective activation of a type of blood cell (T lymphocyte) that normally takes care of the defence system. The skin cells renewal process – which normally takes 28-30 days – speeds up to 3-4 days for psoriatic lesions. The excess cells accumulate on the skin surface and produce the characteristic appearance of red, raised lesions with whiteish flakes. Read More
Pigments that mimic Instagram filters and that blur imperfections, creams with photoluminescent lighting and diffusers that deceive the lens and create the perfect complexion for Facebook, Twitter or a video conversation via Skype or Facetime... Cosmetics are adapting to the social networks. And new skin care and makeup products are taking the fashion for selfies into account.
This is about more than just technology. In fact, optical modifiers – which conceal skin imperfections and irregular contours (fine lines, age spots and large pores) by the diffuse reflection of light – have been around for several years.

Some products only include ingredients that modify how light is reflected. Read More
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
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.
