    The skin and environmental stress

    15 Dec 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 bodyai??i??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 itai??i??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

    Winning the battle against skin dehydration

    30 Sep Winning the battle against skin dehydration

    Our skin contains natural ingredients that protect it and keep it hydrated. These substances form the outermost layer of the skin (the stratum corneum). When the functioning of this outer shell is disrupted, our skin loses water. Dry skin is a common problem that is tricky to resolve. But why does our skin become dry?

     

    We wash too often, use highly alkaline soaps and expose ourselves to excessively dry air from heating and cooling devices. Often we lead a lifestyle that does not allow the skin to follow its natural regeneration cycles. We know that hydrated skin is essential for the epidermis, most especially its outer protective layer, to retain its structure and function properly. When its barrier function is altered, the skin loses water and shrivels like a leaf, which is when we notice discomfort and even itchiness. In short, the skin dries out. Read More

Liposomes are not absorbed by the skinContrary to what was believed until now, the liposomes contained in skin care creams do not easily penetrate the skin. As a result, their function as active transporters of beneficial substances beyond the epidermis is being questioned. At least this is what a new scientific study reports.

     

    Coming as a surprise for liposome-based cream manufacturers is the conclusion of a study, by the University of Southern Denmark and published in the seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat, seroxat. Journal of Investigative Dermatology, that the liposomes only penetrate the epidermis very superficially and so are not properly absorbed by the skin. In other words, the property attributed by science to the liposomes ai??i?? that of being an optimal transporter of ai???encapsulatedai??? active ingredients to the deeper layers of the skin ai??i?? are not so obvious. In fact, the liposomes break into pieces almost as soon as they make contact with the epidermis. The extra cost of the liposome-based products can probably be no longer justified. The authors of the study do acknowledge that certain active ingredients in these cosmetics may be able to reach deeper layers ai??i?? but not via the liposomes, they say.

    The facts about skin hydration

    19 Jun The facts about skin hydration

    All the cells in our body need water to survive and multiply; the cells in the skin are no exception. Pharmacy, beauty centre and perfumery windows typically display hundreds of different skin moisturizing products. Who doesnai??i??t use a moisturizer? But how does a moisturizer work if the skin is virtually impenetrable? Knowing where and how moisturizers work can help us choose the product that best suits our skin type.

     

    The skin tends to dry out more and more as the years go by. So moisturizers are high up in the ranking of bestselling dermocosmetic products. Each time we apply a moisturizer to our skin we are helping the outermost layer of the epidermis protect us against environmental aggressions. This protection, in turn, helps the skin cells carry out the metabolic processes that keep the skin alive and healthy. Moisturizers also reinforce homeostasis, that is, maintenance of the bodyai??i??s internal balance in the face of external changes in humidity and temperature. Read More
