    Microneedling, which can be performed on all skin types, is starting to overtake laser, as there is no burn risk. Also called skin needling or collagen induction therapy, it is a minimally invasive treatment that improves the appearance of the skin and can even treat problems like acne, cellulite and stretch marks. The technique, based on thousands of pinpricks that activate skin regeneration, is the latest in rejuvenation.

     

    Microneedling consists of passing a roller with very short, fine needles over the skin. The resulting tiny wounds open microchannels that cause the body to naturally produce more reparative collagen and elastin. The procedure improves the texture and firmness of the skin and so attenuates scars, stretch marks and even the size of pores. These tiny wounds can facilitate the absorption of other substances that fight the signs of ageing, such as vitamin C, retinol and hyaluronic acid. Read More

    Why do I have open pores?

    Everyone has open pores, but they are more noticeable in some skins than in others. The blame may lie with genetics, as is often the case, but only partly. Temperature and relative humidity, exposure to the sun, skin type, hormonal changes and age also enlarge the pores and make the skin look rough. The question is, however, what’s the solution?

     

    We have about two million pores, which are absolutely necessary for the proper functioning of the skin, as they eliminate toxins, regulate temperature and hydrate the skin. But it's hard to appreciate all this when you can’t help but see them – because they are dilated or dirty from an accumulation of dead cells and other impurities, making your skin look unhealthy and aged. And this is not necessarily for lack of care. Read More

    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

    Winning the war against wrinkles

    "Wrinkles are beautiful," said Adolfo Dominguez, who coined this slogan, famous in the Spanish fashion trade of the 1980s. This is not true, however. According to different sources, the market for dealing with the wrinkles that etch the years onto our skin will be worth 290,000 million dollars by 2015. Youth is purchased at exorbitant prices. And techniques are increasingly sophisticated. But what are these techniques? And more importantly, do they work?

     

    The options are many. And new seemingly impossible combinations are offered, with succulent promises. Basically, however, the techniques can be reduced to either applying something to the skin or removing something from the skin. Applying products to the skin make it appear fresher, whereas removing layers and stretching the skin renews it. This may seem a gross simplification, but it helps understand the panoply of treatments that promise to take years off you. Read More
