We know that the sun's ultraviolet rays cause skin ageing and other dermatological problems, including various types of cancer. Therefore, most of us protect our skin with suitable products and avoid overdoing the sunbathing. But what about people who have to work outdoors?
Farmers, ranchers, construction workers and people in many other jobs are daily exposed to the sun. Ultraviolet rays reaching their skin especially affect the head, lower lip, upper chest area, shoulders, forearms and back of the hands. In contrast, most other people work in offices, workshops and shops and are exposed to the sun only in their free time or on holidays. A review of scientific studies published in a German journal confirms that occupational sun exposure increases the risk of developing squamous cell carcinoma, a malignant cancer that affects 100 of every 100,000 Europeans. Incidence is higher, moreover, in people with fair skin (phototypes I and II). In Germany this carcinoma is rated as an occupational disease, to be communicated officially to health authorities by doctors who diagnose it.
A new testing technique to test toxicity in cosmetics will gradually lead to a reduction in the use of animals. The use of animals is banned in the European Union, but not in other countries (the USA, for example).
Before an ingredient is included in a cosmetic formula, it is traditionally tested on animals to check whether it could be harmful to humans. But many people are against animal experiments for ethical reasons. In vitro testing is a way to avoid this type of testing. As reported in Chemical Research in Toxicology, a new alternative test obtains very accurate results for the allergenic effects of various components on the skin. In fact, test effectiveness is 92% for the allergens with which it has been tested. Good news for animal lovers.
We each have a unique skin. Our protective mantle produces a personal odour that a dog could distinguish between thousands of other smells. Our skin colour is just as characteristic, as no two skins have exactly the same tone. This is what the Brazilian artist Angelica Dass captures in the photos included in her Humanae project.
For Humanae, Angelica Dass has photographed hundreds of volunteers during the year that she has spent travelling in Brazil, the USA, Colombia, France and Bahrain. Each new photo is processed using software synchronized with the Pantone® colour chart to create a record for the skin tone. Pantone® is a code-based colour classification system that allows colours to be accurately reproduced in any medium. It is the most widely used colour standard in industry and the graphic arts sector. Read More
Spring has arrived. It’s getting warmer by the day and, although we may not notice it, our skin is being incerasingly exposed to the sun. Our skin knows how to naturally adapt to new weather conditions, but certain precautions are necessary to keep our skin in the best possible condition.
1. Avoid the sun. This is one of the key leitmotifs of this blog. Use sunglasses and sunscreen (and not just on the beach) and, as far as possible, avoid exposing the skin to direct sunlight. The neckline, neck and hands are especially vulnerable to premature photoageing. For a tanned look, rather than overdo sunbathing, better use a fake tanning cream, taking the necessary precautions first. Read More
