    How to correctly apply fake tan

    17 Feb How to correctly apply fake tan



    The Derm Blog

    We all like nicely tanned skin, even in winter. Tanning booths are an option, but in this blog we have often underlined the fact that doctors do not recommend them. Fake tan is the most effective way to tan in winter. But you need to know how to apply it so that it is not obvious. And you have to use sunscreen.


    Most fake tan products contain between 5% and 9% of dihydroxyacetone (DHA), an ingredient extracted from sugar cane. This is a safe product that rarely causes adverse reactions. It is important to buy a quality product that matches your skin tone so that the result is as similar as possible to that of sunbathing in moderation in summer. It is also crucial to avoid the blotches that appear when the fake tan is not properly applied, which happens if you rush the process and do not follow these simple tips: Read More

    Should we use sunscreen when driving?

    30 Dec Should we use sunscreen when driving?



    Skin Cancer Foundation

    We are increasingly aware of the importance of proper skin photoprotection to prevent skin cancer, especially when outdoors (on the beach or in the mountains). However, we fail to attach the same importance to other daily activities. What happens when we are driving? Can car windows protect us from ultraviolet radiation?


    Last year, a photograph of a 69-year-old man, a truck driver for 28 years, was posted around the world. This photograph, also featured in our blog, clearly shows how ongoing sun exposure was much more evident on the left side of the face. The fact is we rarely consider using sunscreen in the car. A recent study made among skin cancer patiens shows that, even being aware people, few applied sunscreen when in their car, even though they usually did so when outdoors. The reason is they didn’t think it was necessary, especially if driving with the windows closed. Read More

    Seaweed to rejuvenate the skin

    20 Dec Seaweed to rejuvenate the skin



    Cosmetics Design

    Seaweed (alga) is a hit in the anti-ageing skin care market. Many cosmetics are using seaweed as their star ingredient, attributing it with beneficial properties for enhancing our appearance. Creams and lotions of all kinds are prepared from "seaweed extract". How genuine is its anti-ageing properties? Or is this a question of misleading advertising?


    Many companies, especially from France, Canada, the USA and Australia, sell harvested seaweed extract as an ingredient for personal care products. Their advertising usually emphasizes that the extract is a very useful anti-skin-ageing alternative. Algae are organisms that are simpler than land plants. There are thousands of species worldwide, some used since time immemorial for various purposes (in China they have been used since 5,000 years ago). Read More

    Energy-saving bulbs affect the skin

    4 Sep Energy-saving bulbs affect the skin



    British Journal of Dermatology

    Our skin is the shield that protects us from external aggressions. But ultraviolet (UV) light can pass through it, affecting its internal layers and causing photoageing and possibly even greater damage. Modern energy-saving bulbs, unlike the traditional incandescent and new LED lights, emit UV rays that can damage the skin.


    European Union scientists have long warned that energy saving bulbs, known as compact fluorescent lamps (CFL), may have negative effects on the skin’s health because they emit ultraviolet (UV) rays like the sun. In fact, at distances of under 20 cm these effects appear to be demonstrated, especially for people with previous skin problems. Fluorescent lamp manufacturers state that quality products have a dual layer that reduces the radiation, leaving it too weak to cause skin cancer. But, just in case: buy reputable bulbs and keep your distance!
