    Daily care of dry skin

    24 Dec Daily care of dry skin

    Understanding our skin and its needs should be the basis for our choice of cosmetics, so if you have very dry skin, you need to use products that are specifically formulated to treat dry skin and that also take into account your life stage. Below we provided some basic guidance for people with very dry skin.

     

    Dry skin has various causes, among them, genetics, aggressive drugs, overexposure to cold or sun, natural ageing, etc. But dryness is always the result of two factors: lack or excess loss of water (dehydration) and deficient sebum secretion by the sebaceous glands. A healthy, elastic, comfortable-feeling skin requires an optimal level of water in the stratum corneum. Certain components in dry skin are altered, but can be restored by suitable cosmetics. Hydration is the best way to maintain youthful skin and delay the onset of signs of ageing. Read More

    Annals of Internal Medicine

    Just over a year ago we published scientific evidence on the effectiveness of sunscreens against wrinkles. Since then the cosmetics sector has included sunscreen in many products, like make-up, with good results. The message is clear: sunscreen is crucial. Always.

     

    In June 2013, the Annals of Internal Medicine published the results of a major study, conducted in Australia over four years, which underlined that wearing sunscreen daily helps prevent wrinkles. In fact, the study, a milestone for professionals in terms of duration and scope, underlined that a sun protection factor (SPF) of 15 is more effective than taking nutritional supplements, such as beta-carotene, to preserve the skin.

    The skin and environmental stress

    Air pollution, extreme temperatures, artificial light, ultraviolet radiation, noise, cigarette smoke and traffic fumes: all these environmental stressors threaten the health of our skin. Recent studies show that when the skin is continuously exposed to various forms of environmental stress it ages much faster and becomes vulnerable to diseases such as cancer.

     

    The skin is the wrapper that connects us to the environment and protects our body from the inclemencies of the weather. This is hardly surprising, as the skin is the body’s organ that suffers most when our living environment is toxic and inhospitable. Our skin reflects everything, whether it comes from within or without, whether it’s psychological problems, the repercussions of what we eat, the air we breathe or what touches our skin. Living conditions in large cities and industrial areas have created new problems for our skin, designed to be able to adapt to temperature and humidity variations in natural habitats. Read More

    Day or night, mosquitoes are very annoying when they attack our skin. In some parts of the world they also transmit serious diseases. Popular lore and scientists describe several ways to avoid their bites. But mosquitoes are hugely adaptive...

     

    Apart from a pepper derivative called icaridin, N,N-Diethyl-meta-toluamide, known as DEET, is one of the most studied and widely used insect and arachnid repellents. However, according to a recent study published in the Plos One journal, DEET is losing its effectiveness against mosquitoes and the reason is that exposure to this chemical changes their olfactory system. In other words, the mosquitoes get used to the smell and carry on as regardless. So what alternatives are there? Read More
