Cryotherapy is a dermatological technique that uses extreme cold to treat superficial skin lesions, usually through the application of liquid nitrogen. This freezes and removes affected tissue, fully respecting the surrounding healthy tissue. The medical and cosmetic outcomes are much better than for other techniques.
Although the use of cold in medicine may seem to be relatively recent, the Egyptians, aware of its analgesic and anti-inflammatory effect, used cold as far back as 2500 BCE. The technique became popular in the nineteenth century, especially given its analgesic properties, particularly useful for amputations. But the key to the further development of this technique was always the ability to cool, store and handle gases at low temperatures. Read more
The growing popularity of smartphones and tablets worldwide has led to the emergence of thousands of medical apps, a good number referring to care, problems and disorders of the skin. Some are professional tools that facilitate the work of doctors, but others are aimed at the general public. Are all of them risk-free? Can we safely use them for our skin?
Some 40,000 medical apps are available; most likely you have already downloaded some to your mobile device. Undoubtedly, these new technological advances will bring great benefits to the world's population in the future. Creators of apps have not failed to notice the growing interest in skin care, which explains why hundreds of apps are available today offering tips to keep our skin healthy and beautiful and diagnosing all types of skin disorders. There are even apps that will tell you if a mole could be cancerous. Most skin care apps are free. Read more
This blog did not yet exist when the Skin exhibition was held in London as an invitation to reflect on our most overlooked organ. Our skin protects us from external aggressions, enables us to feel and transmits cultural characteristics.
Skin is a philosophical journey to the skin through images, the earliest anatomical illustrations, works by contemporary artists (e.g., biological jewellery made from epithelial cells) and scarifying, tattoos and other cultural expressions. The exhibition also explains how dermatology came into being as a medical specialty in the 19th century. The curator of the exhibition, which, fortunately, can still be visited online, was Javier Moscoso, a science historian and philosopher with the Spanish Advanced Research Council (CSIC). Although readers may find some of the images very graphic, we strongly recommend a visit to the exhibition website.
