    Exercising rejuvenates the skin

    26 Jul Exercising rejuvenates the skin



    The New York Times

    Exercising is less expensive than wrinkle creams and is, judging by a recent study from McMaster University in Ontario (Canada), more effective. Exercising improves the appearance of the skin and slows down the signs of ageing, even in those who take it up late on in life.


    According to researchers at McMaster University, after the age of 40, men and women who do at least three hours per week of sport have smoother, healthier skin and a thicker dermis than the average for their age cohort. In other words, their skin resembles that of people aged 20 to 30 years old. Although it is still unclear what changes exercising brings about in the composition of the skin, these scientists think the anti-wrinkle effect may be due to the paracrine action of the muscle-produced myokine hormone, which induces changes in specific receptors in neighbouring cells.

    Cosmetics for ‘selfies’

    25 Jun Cosmetics for 'selfies'



    Cosmetics Design USA

    Pigments that mimic Instagram filters and that blur imperfections, creams with photoluminescent lighting and diffusers that deceive the lens and create the perfect complexion for Facebook, Twitter or a video conversation via Skype or Facetime... Cosmetics are adapting to the social networks. And new skin care and makeup products are taking the fashion for selfies into account.


    This is about more than just technology. In fact, optical modifiers – which conceal skin imperfections and irregular contours (fine lines, age spots and large pores) by the diffuse reflection of light – have been around for several years. Social networks, however, have meant that they are now centrally placed on shop shelves. These filters are essential to deceiving the eyes and mitigating the effects of ageing. Some products only include ingredients that modify how light is reflected. Read More

    Matrixyl, the secret ingredient

    23 Apr Matrixyl, the secret ingredient



    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

    Enzymes for skin care

    21 Mar Enzymes for skin care



    The New York Times

    Enzymology is a new research area in dermatology and cosmetics that tries to discover how enzymes can improve skin appearance and prevent skin problems. Pharmaceutical companies study enzymes associated with skin disorders, whereas the cosmetics sector is interested in enzymes that enhance the beauty of the skin. However, including suitable enzymes in the diet is currently the most natural and effective way to achieve a healthy and beautiful skin.


    To remain healthy and vibrant the skin needs to be nourished with fats, proteins and carbohydrates. For these substances to act optimally on skin tissues, they need certain small molecules, called enzymes, to accelerate chemical reactions. Enzymes help food pass from the blood to the skin, develop beneficial fats and repair collagen damaged by ultraviolet rays, just to name a few of their many functions. There are many kinds of enzymes. Those most frequently used in cosmetics, called proteolytic enzymes, break down proteins so that the skin can better absorb their components and so promote cell growth and renewal. Read More
