    Nail art: creativity for the nails

    26 Jan Nail art: creativity for the nails



    Cosmetics & Toiletries

    The nails are the strongest part of our skin. Their main component is keratin, a tough protein that is also present in the cells of the stratum corneum (the outermost part of the epidermis). Historically, nails in good condition have denoted good skin hygiene and so are synonymous with health. Nail art refers to the fashion of a sophisticated nail display.


    In the long history of humans, nails have been used to defend, attack, scratch or tickle or as a primitive tool. Nowadays we use them to play stringed instruments, for biting if we are nervous, but above all, for decoration. Although the crisis is affecting global sales of cosmetics, nail product purchases increased 25% in 2012, with the trend continuing on an upward trend. The nail-art fashion allows for great creativity and is a small personal care luxury that anyone can afford. Read More

    Winning the battle against skin dehydration

    30 Sep Winning the battle against skin dehydration



    Dermatologic Therapy

    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

    The facts about skin hydration

    19 Jun The facts about skin hydration



    Skin Therapy Letter

    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 doesn’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 body’s internal balance in the face of external changes in humidity and temperature. Read More

    Fake tanning: bronzed skin, no cancer risk

    28 Mar Fake tanning: bronzed skin, no cancer risk




    Mayo Clinic

    Fake tanning products are the perfect solution for people who like to have a bronzed skin all year round, yet want to reduce the negative effects of solar radiation and prevent skin cancer. Here we consider the advantages and disadvantages.


    Current sunless tanning products have come a long way since the first such products were launched on the market in the 1960s. Such products were not entirely successful, however, due to the uneven and orangeish tan they produced. Current tanning products not only give a more natural, long-lasting colour, they cater for all tastes and skin types. They come in different forms (cream, gel, spray, wipe, etc) and often offer additional benefits (as moisturizers, sunscreens, anti-wrinkle products, etc). Read More
