    Cosmetic Science Technology

    Matrixyl is the registered trademark of an anti-wrinkle ingredient that many rejuvenating cosmetic manufacturers include in their formulations. This is a surprisingly effective and reasonably priced ingredient, yet we still pay fortunes for anti-wrinkle creams. What is this component and how does it work?

     

    The press published the news last year. Compared to invasive anti-wrinkle techniques such as collagen injections or more sophisticated technqiues such as fibroblast cultures, cosmetic products based on Matrixyl double the amount of collagen in the skin, reversing ageing effects dramatically. The fact is, this ingredient seems to deliver what it promises: rejuvenatation of the skin. As happens with clones, Matrixyl contains certain synthetic elements that are almost identical to natural matrikines, which are peptides responsible for preserving and repairing skin tissue. In fact, even before matrikines were used as anti-wrinkle agents it was already known that they impede the proliferation of skin tumours and accelerate the healing of skin wounds. Read More

    Skin-to-skin contact benefits premature babies

    16 Apr Skin-to-skin contact benefits premature babies

    Much has been written about the physical and psychological benefits of newborn contact with the mother, a fact which has been confirmed in numerous scientific papers. In the first moments of life the skin plays a crucial role. A new study of premature babies confirms this.

     

    Ruth Feldman, a professor at Bar-Ilan University (Israel) and her collaborators spent ten years analysing the long-term effects of different levels of physical contact with pre-term babies. The researchers compared premature babies cared for only in incubators with other premature babies who had one hour of skin-to-skin contact daily with the mother. Studies were conducted seven times in the first ten years of life of the children. The results for children who had contact with their mothers indicate better cognitive and executive functioning, enhanced neuroendocrine response to stress, a more mature autonomic nervous system and better cognitive control. These scientists suggest that physicians should incorporate this technique in routines for managing newborns.

    Children: When Things Get Itchy

    Their skin is immature and more susceptible to aggression from the world around them, which makes it easier for them to get scratches, rashes and infections. They run, jump, play and sometimes get hurt. Their skin breaks out, they scratch it and don't want to apply cream. But it seems like everything they get eventually goes away and they go back to normal. But children's skin also needs basic care.

     

    Once they get past the nappy rashes and unexplained red patches of their baby years that finally disappear with patience and the application of moisturizer and repair cream, it seems like the only thing to worry about to keep a child's skin healthy is daily hygiene and sunscreen. You might also remember to cut out the labels from their clothing, since they are usually made of scratchy, synthetic material. Read More

    10 key questions regarding mineral oils

    Mineral oils have been used in cosmetics for the last hundred years. In recent decades they are among the components that most confuse consumers. The myths and misconceptions are many. How do mineral oils affect the health of the skin? Are they carcinogenic? Do they cause acne? Are they “natural”? Are vegetable oils safer?

     

    1. Which cosmetics contain mineral oils? We can answer this question more quickly by formulating the question in reverse, as these oils are the most common components in cosmetics. Paraffin oil, petroleum oil, liquid paraffin, white liquid petrolatum, white oil, petrolatum (vaseline), mineral oil, silicone quaternium, methylsilanol, microcrystalline wax – they go by many names. If any of these ingredients are featured on a label, it means that you are applying mineral oil to your skin. Read More
