The Determinant Factor Of Intrinsic And Extrinsic Aging Essay

Many people think that is it possible to achieve a “healthy tan,” but this thought has been proven wrong. Overexpose to UV-A and UV-B rays from the sun lead to premature aging of the skin, as well as the possible formation of skin cancer, know as melanoma. An appearance of a tan is actually a stage of burning and damage to the skin. Although a tan may be desirable to many, the fact remains that more people need to be educated on the dangers of the sun’s harmful rays, and the possible health complications of overexposure.

Thesis: Many people do not use sun protection on a daily bases and are unaware of the health effects of sun exposure that can be easily preventive by using sun protection.

Doctors recommend that to give skin the fullest protection from ultraviolet rays, people should use plenty of sunscreen, limit sun exposure, and wear protective clothing. The most common sunscreens today are known as “broad spectrum” because they block out both UVA and UVB rays. These lotions don’t feel any different on the skin from the old UVA-only types, but they work better at preventing premature aging and skin cancer. Many sunscreens claim to be waterproof, but they will hardly provide adequate coverage after extended periods of swimming or perspiring. To protect well, even waterproof sunscreens should be reapplied liberally and often. All areas of exposed skin, including ears, back of hands, and tops of feet, need to be coated well to

In today's world, there is a large amount of emphasis on physical beauty, youth, and how to stay younger for longer. Although many have condemned this as a particularly shallow approach to life, there is also an underlying concern for physical health, which is at the bottom of longevity and a concomitant better-looking physique. Indeed, the longer a person can maintain a healthy lifestyle and a focus on self-care, the longer he or she tends to maintain a relatively youthful or at least healthy demeanor. This has also become a growing concern as life expectancy has increased almost exponentially for human beings over the last century. For this reason, companies such as Dr. Perricone MD Skincare continue to do extensive research to determine ways in which the longevity and youth of the skin can be prolonged and even restored.

Some people are born with more melanin than others. People with dark skin have more melanin than people with light skin. Some people are born with no melanin at all, and they are called albinos (Stewart, 10). Too much time in the sun produces extra melanin which protects the skin from the sun’s rays, and also makes lighter skin get darker, or suntanned. But if too much time is spent in the sun, it can result in a sunburn, and this can lead to skin

Discrepancies between the investigational and model outcomes indicate the necessity to restructure auxiliary variables of the model. The addition of constituents to the model e.g. skin whitening, promotes improved explanation of the investigational data, and novel biological and physical experiments may be endeavoured to investigate unidentified procedures involved in and affecting melanin production in the skin with regards to UV radiation. Critical parameters e.g. UV radiation, act as a guide for new experiments to concentrate specifically on the model of melanin

Results: In a sample of 28, 18 were males and 10 were females. Mean age was 46.7

The color of a person’s skin is therefore an obvious indicator of the likelihood of getting sunburn and subsequently developing skin cancer. At present, a cancer is termed “common” if there is annual incidence of 30,000 cases or more. One out of every three newly diagnosed cancers is a skin cancer and approximately one million new cases of skin cancer are diagnosed in the United States every

Much of the sun damage that can result in long term consequences has already been inflicted. The Telegraph published an article in 2010 stating that the elderly tend to not visit their doctors as often, which results in prolonged diagnosis of skin cancer that is typically more difficult to treat (Smith). Though occurrences of skin cancer do increase with age, there are so many elders being diagnosed at advanced stages that it is highly important for elders to pay attention to any changes in their skin or moles in order to catch it earlier (Smith, 2010).

Melanoma is the second most diagnosed cancer among young adults, ages 20-39 years (Bleyer & Barr, 2009). Risk factors for developing skin cancer are greatly influenced by behavior, such as failing to adequately protect oneself from ultraviolet radiation (UV) exposure from the sun (Gandini et al., 2005). Young adults have especially high rates of UV exposure (Coups, Manne, & Heckman, 2008). However, 50 to 85 percent of them fail to properly protect themselves from the sun (e.g., wear adequate sunscreen; Cokkinides, Weinstock, Lazovich, Ward, & Thun, 2009; Jones, Saraiya, Miyamoto, & Berkowitz, 2012). For these reasons, it is important to investigate psychosocial correlates of sun protection behavior in this population in order to help design effective interventions.

Let’s face it (no pun intended); the aging process is tough on everyone’s skin. Add in the effects of pollution, over exposure to the sun’s harmful radiation and the rigors of everyday stress, and your skin is in need of instant relief. In addition, keeping your skin fresh, glowing and radiant should not be a chore that involves multiple steps and products.

According to Brown & Phillips (2010) several biological process in the skin require nutrients for proliferation. The

If your family history includes sensitivity to the sun, you are at risk of developing a sun allergy. Embedded in our immune systems are genes to protect our skin. When the system defenses are overpowered physically, a chemical change occurs inside of the body triggering the immune system to react with one of the

A major function of melanin is to act as a defensive barrier of the skin against radiation damage. Ultraviolet light between the wavelengths 280-320nm (UV-B) causes sunburn and damages the skin on nonpigmented peoples. Exposure to this degree of light causes their skin to become dry, leathery, and wrinkled in appearance similar to that associated with aging. This can be seen in Whites living in Australia and South Africa, where ultraviolet light intensity is high because of the relative latitude or closeness to the equator.
