    Collagen injections

    21 Feb Collagen injections




    In looking for the elixir of eternal youth for our skin we don’t think twice about an injection or any other kind of pain. But are treatments definitive? Do they turn back time? Collagen is one of the hottest options available at present.


    Collagen is the main fibrous component in the skin and bones. A quarter of the protein mass in our body is collagen, which forms 75% of the connective tissue. Collagen acts as the scaffolding for our skin. One cause of sagging skin is reduced collagen content. Collagen injections are used mainly to fill in areas of the face that have lost firmness and become wrinkled due to the passing of time. The main function of collagen is as a filler material for empty spaces in the deeper layers of the skin, thereby eliminating the fine lines that so many people dread. Read More

    Babies: a daily bath?

    17 Feb Babies: a daily bath?




    Newborns are vulnerable, yet are often stronger than they look. Adults instinctively feel the need to protect them and this sometimes means excessive care that is counterproductive. Keeping a baby’s skin clean and healthy, for example, is not complicated.


    Newbie parents are often assailed by doubts about the abundance of skin care products and tips regarding babies’ skin. Everyone naturally wants the best for their newborn baby, so paediatricians at the Mayo Clinic recently issued some recommendations in the International Journal of Dermatology. The most surprising recommendation is to forego the widespread custom of daily bathing and bathe the baby only every second day. On non-bathing days the body and face (including the eyes and eyelids) can be cleaned with just a water-dampened washcloth. As for the bath, tap water is fine and products, if used, should be gentle, dye- and fragrance-free and with a pH between 4.7 and 5.5. After changing nappies, the baby can be cleaned up using a little water and the naked skin should then be allowed to breathe for a while. Baby wipes should be hypoallergenic and without lanolin or alcohol. For nappy rash, a zinc oxide-based product can be used.

    Better quality of life thanks to cosmetics

    9 Feb Better quality of life thanks to cosmetics



    Archives of Dermatology

    A large study sponsored by a major cosmetics firm shows that body and skin care and the use of cosmetics contribute significantly to a positive outlook on life. A specific questionnaire has been created as the basis for future research in this area.


    Our appearance is important to us and may be a key factor in perceptions of our physical and psychological wellbeing, in other words, of our quality of life (QoL). A questionnaire developed for this above-mentioned study, called BeautyQoL, consists of 42 questions covering five areas: social life, self-confidence, mood, energy and attractiveness. A total of 3,231 adults, recruited from 13 countries in Europe, Asia, America and Africa, participated in the study, in which subjects also completed other standard QoL questionnaires used by researchers in this field. The results scientifically demonstrate that people who care about their appearance – in most cases by using cosmetic products – have a better quality of life than those who do not.

    Perfume: why does it smell different on each person?

    17 Jan Perfume: why does it smell different on each person?



    British Journal of Dermatology

    Have you ever wondered why people smell different even though they wear the same perfume? Individual skin naturally contains a particular cocktail of chemicals that, rather like a fingerprint, leaves a unique aroma. When perfume blends with a person’s body odour it takes on a life of its own and creates a unique mark of identity.


    At perfumeries, fragrances always smell just as their creator designed them. But they take on a different life on individual skin. We now know that we all give off a different body odour because everyone’s skin is composed of various chemical substances that, on evaporation, are transmitted by air and can be perceived by smell. These substances, known as volatile organic compounds, are part of all living organisms. Humans secrete them though two types of skin gland that produce sweat: eccrine and apocrine glands. When we apply a perfume, our natural body odour and the fragrance blend together and produce a specific, unique cocktail. But how do they blend? And why, once we are wearing it, does a perfume smell nothing like its creator planned? Read More
