Advantage And Disadvantages Of Sunscreens

The purpose of this experiment was to test which type of sunscreen worked better, spray or lotion. The experiment was conducted by cutting a UV paper into squares and labeling each one with each of the six sunscreen. A small amount of each sunscreen was applied to a square and was taken outside for three minutes to be exposed to the sun. The UV squares were taken back inside to be soaked in water for one minute each. The squares were left to dry for twenty-four hours. Three trials were conducted for each sunscreen. After the twenty-four hours of drying time and for the results to fully come in, immediately it was noticed that the lotions made the UV paper much lighter than the sprays. For all three trials, sunscreen number two, made the UV paper the whitest, meaning it protected the UV paper from sun exposure more.

By using sunscreens, people can extend their time under the sun to 5 hours, and not 1 without getting a sunburn. They also prevent brown spots appearing on skin and skin discolorations. Sunscreens aren’t all the same, they are rated from 4 to 50 or even larger numbers. These are the values of time a person can stay protected under sunlight while wearing the sunscreen, which is also called the Sun Protection Factor

Dermatologists, physicists, and scientists conducted a workshop of UVA treatment, and the workshop’s findings are presented in the New England Journal of Medicine. A previous president of the American Academy of Dermatology wrote an article titled “UVA1 is Often A1” to discuss their findings. The workshop found that medium or high-dose UVA1 works well with morphea, urticarial pigmentosa, atopic dermatitis, dyshydrotic dermatitis, subacute pruigo, and systemic lupus erythematosus. These diseases are treated by UVA rays because the wavelength is longer, which means there is less energy delivered to the skin and the greater penetration of photons (Dahl, 2012). Dermatologists even use sunbeds with higher intensity than regular tanning beds in their offices. For example, Windsor Dermatology uses four different types of light therapy to treat the skin condition psoriasis. One type of light therapy is that of UVA. The anti-inflammatory properties of ultraviolet light aid in slowing the growth of psoriasis effected skin

Seasoned day hikers know the importance of sunscreen and protecting their skin from excess rays.

Ultraviolet, or UV rays can damage skin cells which can lead to skin cancer. The SPF on sunscreen bottles stands for Sun Protection Factor, and refers to how well the sunscreen protects our skin against one type of UV radiation, called UVB. Some of the UV radiation from the sun still gets through the sunscreen and gets absorbed by our skin. Sunscreens are usually made up

Tanning was one of my favorite summertime activities growing up in the Midwest; it was a great thaw after a long, cold winter. During that time, baby oil was the choice of tanners whose goal it was to achieve the deep, rich golden colors of summer. Sadly, skin damage was caused summer after summer as the integumentary system was barraged with UV rays, knocking its system out of homeostasis.

Several findings are made based on the results: UV radiation can cause cell death by inducing genetic mutation, which agree with Diepegen et al. (2012)’s finding regarding UV radiation’s destructive effect at a cellular level. Photoprotective agents can effectively prevent and reduce UV radiation induced damage to cells. Similar findings were made by Quatrano and Dinulos (2013), who indicated that sunscreen contains active ingredient that absorbs UV radiation ranging between 290-400 nm. This experiment proves that photoprotective agents with higher SPF values are more effective in absorbing UV radiation. Indicated by Green et al. (2011), they suggested that regular application of high SPF sunscreen will prevent melanoma.

This study focuses on the procedures of tanning, the benefits of tanning, and the factors that drive people to tan. To understand the pop culture trend of tanning, six girls who participated in tanning whether it be indoor or outdoor, were interviewed to get an inside view of what tanning consist of and why people choose to tan. Tanning is an activity many partake in to avoid pale skin. Not only do most know the risk of tanning but they also know at least one other person that tans.

Sunscreen - protecting the body with sunscreen - yes, even the penis - is crucial, principally during the summer season, when the sun's rays are at their strongest. However, now not all sunscreens are made alike, and a few may just contain chemical substances which can reason irritation. PABA, a substance most commonly found in sunscreen, often explanations disorders in participants with touchy skin; men who come across problems can are trying a PABA-free sunscreen as an alternative.

Ultraviolet (UV) radiation is present in normal sunlight and sunlamps. “The sun emits energy over a broad spectrum of wavelengths: visible light that [one] can see, infrared radiation that [one] feels as heat, and ultraviolet (UV) radiation that [one] cannot see or feel. UV radiation has a shorter wavelength and higher energy than visible light. It affects human health both positively and negatively” (U.S. EPA). There are multiple types of ultraviolet radiation known to scientists and each affects human in different ways. “The longer ultraviolet rays (UVA), which penetrate deep into the skin, are responsible for tanning. Shorter rays (UVB) damage superficial skin cell layers, causing sunburn” (Harvard). Medical researchers at the Skin Cancer Foundation found that “the cumulative damage caused by UV radiation can lead to premature skin aging (wrinkles, lax skin, brown spots, and more), as well as skin cancer” (Skin Cancer Foundation).

Maintain coverage. Sunscreen is only effective as long as it is on your skin. After awhile in the sun, it's natural for sunscreen to start wearing off due to activity, sweating, bring rubbed off from clothing, or from going into the water. It's always a good idea to reapply periodically... just to be on the safe side.

Finding a product which offers superior UV protection while hydrating and moisturizing your skin at the same time gives you double the impact. That is what you get from EltaMD UV Daily Broad-Spectrum SPF 40.

--The lighter your skin tone, the more protection you’ll want. This means that you’ll need to use a cream with an SPF (sun protection factor) of 30+. If your skin is darker in tone, you’ll want a cream with SPF 15+. Regardless of your skin tone, the cream needs to be reapplied every couple hours. For the best facial protection, buy your cream from a professional cosmetic

For this year’s science project, I would like to test the effects of both mineral and commercial sunscreens on human skin and coral reefs. In current news, the island chain and United States’ state, Hawaii is planning on banning common sunscreens for the detrimental effects on the coral reefs. I would like to test the sunscreens for the detrimental effects on human skin as well to answer the common question, “Why should I care?” With this project, I will be able to educate the public on not only the effects of chemicals on marine life, but also on humans as well. Also, determine if there is a way not to wear sunscreen at all and still be protected from the sun’s UV rays.

A layer of shea butter on the skin helps absorb the radiation of the sun, so it doesn't damage the skin.
