How to Protect Skin-Part IV

Yes, enjoying a sunny day on the beach is fun. However, when going out without proper skin protection one is risking himself of having skin diseases, one of which is the dreaded skin cancer. So to maintain the healthy, youthful glow of one’s skin, it is indispensable to understand how the bad effects of the sun’s ultraviolet or UV rays come into action. (Here’s where you can find more detailed information on skin care and stretchmark removal cream.)

The UV-A and UV-B rays penetrate clouds, thick layers of glass, a meter of water, and the layers of the skin. UV-B makes the skin’s top layers to release chemicals that permit the blood vessels’ expansion and cause some fluid to leak, resulting to inflammation, pain and redness known as sunburn. This damage can occur within an approximate of only 15 minutes and can continue to worsen for up to 72 hours after sun exposure. The damaged skin cells in the process will die and “molt off” in sheets or pictures. Peeling is the process in which the body disposes of dead skin cells. UV-A are the rays that get into the deeper layers of the skin. This affects the living skin cells under the surface of the skin. These rays not only bring about long-term damage such as sagging, wrinkles and discoloration, they also give way for the early stages of skin cancer.

Here’s some “geek speak” that’s worth some brow-burning. The UV rays act like chain saws, shredding deep into the DNA (the genetic material, with a very precise structure, specific order and specific coding) found within the cell nuclei. Repair enzymes within the cell act by countering the damage done on the DNA chain in shortest period possible. This damage and repair happens simultaneously and continuously with the tempo of the repair keeping up with the extent of damage being inflicted. But just like any other mechanism within the body, these repair enzymes have their limits and reaches the point that they can no longer work. When the damage is too much (which occurs even before the skin turns red), the enzymes cannot cope. The result is a dismantled DNA structure which alters the coding and leads to the abnormality of skin cells or what is termed as mutation. This is the first step of the formation of cancer cells. UV-rays also contribute to the formation of superoxides which are extremely toxic chemicalsthe speeds up skin cell ageing.

Skin cells produce melanin, a pigment that gives the skin its characteristic color.
