Harmful Radiations Of The Sun
The sun emits three form of radiation infrared, visible and ultraviolet. Infra red and visible light are valuable because they provide warmth and the ability to see. Ultraviolet rays can be harmful depending on their wave-lenght:- UVA (longest), UVB (middle length) and UVC (shortest). Each one them penetrates the atmosphere and affects our health in different ways.
UVB Rays: These rays are absorbed into the epidermis and can cause skin cancer by altering the normally well-organized behavior of cells. By breaking down the collagen and elastin building blocks they can create , by further causing wrinkles, clumping up the protein, weakening the walls of small blood vessels and spider veins etc.
UVA Rays: These rays can be as harmful as UVB rays. UVA is absorbed into the epidermis and pass through the dermis. They remain in high intensity all day long and not just peak hours of 10 a.m. to 2 p.m. unlike the UVB rays.
UVB and UVA rays can both damage the protecting covering of eyes known as Cornea. The resulting damage to the lens and the retina may cause cataract and visual acuity problems.
The sun also affects the immune system UVB and particularly the UVA rays can damage the langerhans cells, which are important component of immune system within the skin. UV rays can damage the WBC (White Blood Cells) as well, rendering them important in face of the enemy. In addition damage to the langerhans cells and WBC can reduce the effectiveness of the immune system leading to vulnerability of the skin to viruses and other diseases.
UVC Rays: These rays are absorbed in the ozone layer and if small amounts of these rays succeed in passing through, they are absorbed in the epidermis of the skin.
Preventing or diminishing wrinkles
Long term exposure to the sun is one of the major cause of wrinkles, other being progressive ageing.
The skin begins to sag, as the elastic collagen fibers in the skin weaken, making the skin less resilient and supported.
After the age of twenty-five, regular facial massage helps to preserve the elasticity and resilience of the skin by improving the circulation of blood to the surface of the skin.
You can buy various collagen products to apply to the skin, but it has not been proved that collagen can penetrate the skin in sufficient amounts to restore your own collagen tissues.
Consult a dermatologist before choosing a product for use. There are other ways to remove wrinkles like injecting of collagen fibers to fill out prominent and fine wrinkles, removal of flabby skin by a plastic surgeon. But these are not permanent solutions and also need to be tested for sensitivity before you can be treated.
Although wrinkles are not medical problems, some people seem to resort to them. Thus, make sure the doctor who performs the procedure is qualified, trained dermatologist or plastic surgeon.
