3 Reasons why you need to start wearing Sunscreen daily!

What happens to your SKIN when you don’t wear SUNSCREEN

Read before you decide to skip on the SPF! Sunlight has a severe effect on the skin that can result in the premature aging, skin cancer, and a host of other skin-related conditions. Exposure to ultraviolet (UV) light deems for around 90 percent of all symptoms of skin damage. Three reasons why you need to start wearing sunscreen daily:

1. Collagen Break Down

Collagen is the protein in your body that keeps your organs in place and your skin tight. UV radiation can cause collagen to break down at a higher rate than normal aging (this is why skin sags as people age). It does this by penetrating the middle layer of skin (dermis), causing the abnormal buildup of elastin.

Elastin fibers are what gives your skin elasticity; UV rays break down the elastic. In turn, the exposure to the rays causes dryness and premature aging.

Sunlight causes the accumulation of abnormal elastin, which in turn results in the production of large quantities of metalloproteinases. Metalloproteinases aid the recovery of sun-damaged skin by producing and reforming collagen. However, the creation of large amounts of metalloproteinases can reduce their effectiveness and cause collagen to be broken down. The result of the repetition of this imperfect rebuilding process is the development of wrinkles.

At the age of around 30, the rate at which the body produces collagen and elastin starts to slow. As we continue to grow older, the body’s ability to produce collagen continues to decline. When these naturally falling collagen levels combine with skin that has already been damaged by the skin, the result is the loss of moisture, the development of fine wrinkles and reduced elasticity.

As much as I would want Collagen supplements to work, they are a complete waste of money, but of course, supplement companies don’t want you to know that! Collagen is digested before your body can absorb it. I learned this recently in my human biology class.

2. Immune System Effects

The body has a natural protective immune system meant to attack infections and abnormal cell growths, including cancer. This immune defense includes specialized white blood cells called T lymphocytes and skin cells called Langerhans cells. When the skin is exposed to excessive sunlight, certain chemicals are released that actively suppress these cells, weakening the overall immune response.

Also, excessive sun exposure can cause your cells to commit suicide, literally; this results in skin cancer. The body’s last line of immune defense is something called apoptosis, the process of “cell suicide” meant to kill severely damaged cells become they cannot become cancerous. (This is one of the reasons why you peel after a sunburn.) While the process is not fully understood, excessive UV exposure appears to prevent apoptosis, allowing precancerous cells the opportunity to become malignant.

3. Skin Cancer and Melanoma

The ability of the sun to cause cancer is well known. The three major types of skin cancer are melanoma, basal cell carcinoma, and squamous cell carcinoma.

Melanoma is the most deadly of the three as it spreads (metastasizes) more readily than the others. Basal cell carcinoma is the most common and tends to spread locally rather than metastasize. Squamous cell carcinoma is the second most common and is known to metastasize, although not as common as melanoma.

The amount of sun exposure a person receives before the age of 20 is the determining

risk factor for melanoma. By contrast, the risk of basal cell carcinoma or squamous cell carcinoma is related to both a person’s skin type and the amount of lifetime exposure to UV radiation.

A lot of people are concerned with the chemicals found in many commercial sunscreens and have opted for more natural sunscreens. Consumer reports lead an annual sunscreen study that puts many sunscreens to the test and found that many of the sunscreens do not meet their SPF claims. Unfortunately, many of the sunscreens that do not meet their label claims are the mineral or so-called “natural” sunscreens. The following are the best-rated sunscreens for great SPF coverage and low use of chemicals:
