    Microneedling: needles that rejuvenate the skin

    16 Jan Microneedling: needles that rejuvenate the skin



    DermNet NZ


    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

    Daily care of dry skin

    24 Dec Daily care of dry skin

    Understanding our skin and its needs should be the basis for our choice of cosmetics, so if you have very dry skin, you need to use products that are specifically formulated to treat dry skin and that also take into account your life stage. Below we provided some basic guidance for people with very dry skin.


    Dry skin has various causes, among them, genetics, aggressive drugs, overexposure to cold or sun, natural ageing, etc. But dryness is always the result of two factors: lack or excess loss of water (dehydration) and deficient sebum secretion by the sebaceous glands. A healthy, elastic, comfortable-feeling skin requires an optimal level of water in the stratum corneum. Certain components in dry skin are altered, but can be restored by suitable cosmetics. Hydration is the best way to maintain youthful skin and delay the onset of signs of ageing. Read More

    The wrinkle filler crisis

    24 Mar The wrinkle filler crisis



    BBC News Health

    Rejuvenating skin treatments in the form of injections of various kinds have averted the need for cosmetic surgery for many women (and men). But side effects have proliferated, because the products are not always of high quality and the people who administer them do not necessarily have suitable qualifications.


    Would you get a botox or collagen injection at a hairdressing salon or a beauty party? Well, it happens a lot and, in view of the complications, has raised the alarm among doctors. The UK Royal College of Surgeons, for instance, has launched an initiative to ensure that only doctors, qualified nurses and dentists can inject botox, which is actually a powerful neurotoxin. In addition, charlatans offer misleadingly cheap offers and inject diluted hyaluronic acid – and logically the effect lasts half as long. In the USA, the Food and Drug Administration (FDA) has only approved five substances, along with botox, as wrinkle fillers, and all are considered medicines. In Europe, however, almost 50 substances are allowed. If you are thinking about removing years from your face using collagen, hyaluronic acid or botox injections, consult a specialist medical centre. Do not put your skin or body at risk.

    Winning the war against wrinkles

    10 Mar Winning the war against wrinkles



    University of Maryland

    "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
