    Enzymology is a new research area in dermatology and cosmetics that tries to discover how enzymes can improve skin appearance and prevent skin problems. Pharmaceutical companies study enzymes associated with skin disorders, whereas the cosmetics sector is interested in enzymes that enhance the beauty of the skin. However, including suitable enzymes in the diet is currently the most natural and effective way to achieve a healthy and beautiful skin.

     

    To remain healthy and vibrant the skin needs to be nourished with fats, proteins and carbohydrates. For these substances to act optimally on skin tissues, they need certain small molecules, called enzymes, to accelerate chemical reactions. Enzymes help food pass from the blood to the skin, develop beneficial fats and repair collagen damaged by ultraviolet rays, just to name a few of their many functions. There are many kinds of enzymes. Those most frequently used in cosmetics, called proteolytic enzymes, break down proteins so that the skin can better absorb their components and so promote cell growth and renewal. Read More

    Unwanted tattoos

    Part of the fascination of tattoos is that they leave an indelible mark on the skin. Beyond any artistic or literary value, there is something profound about the fact that they are "forever". But the reality is that a third of people eventually come to regret their tattoos.

     

    This is the main conclusion of a study conducted in England and presented at the last meeting of the American Academy of Dermatology. The study also reported that twice as many men as women regret their tattoos – three times as many if they were tattooed as boys (before the age of 16). Interestingly, almost half the respondents (men and women both) had more than two tattoos and 31% had more than five. It all seems logical: in recent decades the fashion for tattooing has seen spectacular growth, with a mushrooming of tattoo parlours in the first world. Many people get a tattoo simply because it is fashionable – and do not dwell too much on the long-term implications. And that they are long-term goes without saying ... Read More

    To what extent are cosmetics safe?

    To try and guarantee that the gels, creams and other cosmetics we apply to our skin every day are not harmful to health, individual ingredients undergo strict controls. Once combined with others in product formulas, they are tested on volunteers before commercial launch to ensure that negative impact on the skin is minimal or non-existent. How are these controls implemented?

     

    Our readers are aware of the fact that European cosmetics legislation prohibits animal testing or the purchase of raw materials from countries where animals are used for safety tests. The testing system currently in use tries to ensure that each individual ingredient is safe. However, ingredients may interact when combined in a product, resulting in new components that might modify the safety of the final product. Current regulations do not state which tests are mandatory, but do indicate that manufacturers are responsible for the safety of their products. The cosmetics industry applies a wide range of tests, depending on how the cosmetic is applied and used (no animals are used, naturally). Read More

    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
