Sun Exposure and Skin Cancer

Sun Exposure and Skin Cancer

The sun’s rays make us feel good, and in the short term, make us look good. But our love affair isn’t a two-way street. Exposure to sun causes most of the wrinkles and age spots on our faces. Consider this: One woman at age 40 who has protected her skin from the sun actually has the skin of a 30-year-old!

We often associate a glowing complexion with good health, but skin color obtained from being in the sun – or in a tanning booth – actually accelerates the effects of aging and increases your risk for developing skin cancer.

Sun exposure causes most of the skin changes that we think of as a normal part of aging. Over time, the sun’s ultraviolet (UV) light damages the fibers in the skin called elastin. When these fibers break down, the skin begins to sag, stretch, and lose its ability to go back into place after stretching. The skin also bruises and tears more easily — taking longer to heal. So while sun damage to the skin may not be apparent when you’re young, it will definitely show later in life.

How Does the Sun Change My Skin?

Exposure to the sun causes:

  • Pre-cancerous (actinic keratosis) and cancerous (basal cell carcinoma, squamous cell carcinoma and melanoma) skin lesions – due to decreases in the skin’s immune function
  • Benign tumors
  • Fine and coarse wrinkles
  • Freckles
  • Discolored areas of the skin, called mottled pigmentation
  • Sallowness — a yellow discoloration of the skin
  • Telangiectasias — the dilation of small blood vessels under the skin
  • Elastosis — the destruction of the elastic and collagen tissue (causing lines, wrinkles and sagging skin)

What Causes Skin Cancer?

Skin cancer is the most prevalent form of all cancers in the U.S. and the number of cases continues to rise. It is the uncontrolled growth of abnormal skin cells. This rapid growth results in tumors, which are either benign (noncancerous) or malignant (cancerous).

There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma and melanoma. Basal cell and squamous cell cancers are less serious types and make up 95% of all skin cancers. Also referred to as non-melanoma skin cancers, they are highly curable when treated early. Melanoma, made up of abnormal skin pigment cells called melanocytes, is the most serious form of skin cancer and causes 75% of all skin cancer deaths. Left untreated, it can spread to other organs and is difficult to control.

Ultraviolet (UV) radiation from the sun is the number-one cause of skin cancer, but UV light from tanning beds is just as harmful. Exposure to sunlight during the winter months puts you at the same risk as exposure during the summertime, because UVA rays are present in daylight.

How Can I Help Prevent Skin Cancer?

Nothing can completely undo sun damage, although the skin can somewhat repair itself, especially with on-going sun protection. So, it’s never too late to begin protecting yourself from the sun. Your skin does change with age — for example, you sweat less and your skin can take longer to heal, but you can delay these changes by staying out of the sun. Follow these tips to help prevent skin cancer:

  • Apply a chemicals- free sunscreen with a sun protection factor (SPF) of 30 or greater (for UVB protection) and zinc oxide (for UVA protection) 20 minutes before sun exposure and every 2 hours thereafter, more if you are sweating or swimming.
  • Select clothing, cosmetic products, and contact lenses that offer UV protection.
  • Wear sunglasses with total UV protection and a wide-brimmed hat to shade your face and neck.
  • Avoid direct sun exposure as much as possible during peak UV radiation hours (between 10:00 a.m. and 2:00 p.m.).
  • Perform skin self-exams regularly (at least monthly) to become familiar with existing growths and to notice any changes or new growths.
  • Eighty percent of a person’s lifetime sun exposure is acquired before age 18. As a parent, be a good role model and foster skin cancer prevention habits in your child.

The most important anti-aging rule is sun protection!

About the Author:

Pure natural cosmetics is not just a name, for me and many others it became a way of life!

All my life I had an affinity to healthy life style. As a dancer and a trainer, i was always looking for the good combination of healthy food and healthy movement.

In time I learned that its not only what you eat that matters. Also what you use as cosmetics or medical products is important.

The skin is the biggest organ in our body. About 60% of what we put on our skin gets into the blood system and with that to the inner organs.

I invest my heart and soul into “Pure natural cosmetics” and the best part is to hear the amazing comments from my client.
