UV protection - sun and skin

Not since the ozone hole is excessive sun bathing for the skin a strain. But whereas in earlier centuries, pale skin for beautifully kept, is nowadays usually tan as the ultimate for very fit, healthy glow.

The dose Strong - too much sun can harm

That the skin on exposure to excessive sunlight (or excessive tanning visit) is aging rapidly and regenerated less well is one thing. Finally, it is personal preference whether one wants to walk around with a skin appearance and structure of the tanned leather, are etched in the wrinkles and furrows. The problem is: the weakened through excessive sunbathing skin is less resistant, such as cancer.

The number of people who develop skin cancer, has in recent years in countries such as Australia, have been disadvantaged under the ozone hole increased. At least that should encourage even the most sun to protect their skin.


Self-protection time - different skin types vary much sun

For Central Europeans have the red or blond hair, freckles and pale skin, the natural protection time than ten minutes (skin type 1). Skin type 2, the blond-haired with pale skin are no freckles, they may be up to 20 minutes in the sun without getting sunburned. Dark blonde to brown hair and slightly tinted skin are the characteristics of skin type 3, which can support up to half an hour sun. Southern Europeans are usually the type 4 skin with dark hair and heavily tinted skin color - their own protection time is longer than half an hour.

Sunscreens extend the time you spend in the sun without the skin verbrutzelt - but it is no use if you repeatedly smear it.

The dose Strong - sun is vital

But sunlight is essential for the health of the other. Only with sunlight, the body can produce vitamin D - which is, among other things important for building our bones prevented, before the osteoporosis.

A light-deficiency disease in northern regions is the so-called winter depression. That's because sunlight stimulates the body that produce so-called happiness hormone serotonin - is missing the sun, then there's too little serotonin.

UV protection in summer

Who in the spring and summer a lot of the outdoors should do something good for his skin and protect it from an excess of sun. Here are some tips for UV protection:
Light clothing, the body mostly covered, long-sleeved shirts, long pants, a hat that shades the face (eg so a chic Australian leather hat ) - which prevents the heat stroke also.

Exposed skin should be moisturised with a sunscreen with high SPF (at least factor 15). Sun creams with mineral particles that reflect light, offer immediately after the application of protection from UV radiation. Other sunscreen products should be some time before the stay to apply outdoors.

lotion before swimming with absolutely waterproof sun cream - even in the water there is danger of sunburn.

After the swim, dry off some cream (every drop of water acts like a magnifying glass) and new.

cell death by anti-aging substance

Rather than smooth out wrinkles, engages in drug DMEA in anti-aging creams collagen-forming cells and kills them.


DMAE (dimethylaminoethanol) is a component of many anti-aging creams. The alcohol with amine function to stabilize cell membranes and thus achieve a toning effect on the skin. But instead of a gentle face lift, the substance can damage the skin dramatically. Scientists came to this conclusion of the Canadian Laval University in Quebec.

As the team Guillaume Morissette in laboratory skin cells with the metabolic product brought into contact, the so-called fibroblasts swelled immediately and violently. These cells in the connective tissue of the skin produce collagen quality important. In the following hours, the scientists observed that the cells divided much more slowly. A considerable part of the fibroblasts died from even. After 24 hours, a quarter of the collagen-producing cells of dead anti-wrinkle effect was stirred ago according to scientists from the swelling of the fibroblasts, which makes the skin appear plumper.

Untested drug effects

Study leader Guillaume Morissette stressed that he was not as a cosmetic ingredient DMAE will condemn in principle, but says also: "DMAE has pharmacological properties, but there are few scientific conclusions about its effect. It is high time to deal with whether the substance is a health risk. "

DMAE, which is found not only in anti-aging creams, but as a tool in many other amenities, is for the scientist not an isolated case dar. Many ingredients in cosmetics were like drugs. But the laws regulating such products are far less stringent than for drugs - a fact that Guillaume Morissette is not justified holds.
