Introduction:
Which brand of sun block will keep you most protected? Sun block is a substance that provides a high degree of protection against sunburn, often preventing most tanning as well as burning, as by obstructing the penetration of ultraviolet rays. Sun block is almost a necessity for most people. Sun block is almost a necessity because certain people burn easily due to having sensitive skin. This could be very painful for certain people and it doesn’t go away easily or quickly.
Two types of radiation that cause skin cancer are ultraviolet A and ultraviolet B. These two UV rays can cause sun burn, skin aging, skin damage, and skin cancer. This is what sun block is for. It protects the skin from these rays that can damage our bodies permanently.
We decided to pursue this project because we all enjoy being outdoors having fun and playing sports. We feel that sun block is necessary because we don’t like having sun burn. Also because when we get older we do not want our skin to age, be damaged, or have skin cancer.
One thing we will talk about is why UV rays affect us. Another thing is how long does it realistically take for sun block to stop working. The last thing is what is in sun block that truly helps us.
This experiment will show which brand will keep us most protected and safe under the earth’s UV rays that are so damaging.
Body:
There are many different reasons to wear sun block. A couple reasons are that without it, you can develop sun burn, skin damage, aged skin, and/or skin cancer. These are common among careless, repetitive tanners and people who refuse to wear sun block when they know they will be outside for a long period of time. It is never okay to not wear sun block when going outdoors.

... because they are the two things that affect our bodies and skin when exposed to the sun. Knowing what SPF and how long your body can handle the sun is also very important because using an SPF that is too low could leave harsh effects on our body and so could being exposed to the sun for too long. Knowing what ingredients in sun block protect us is a good thing to know because when purchasing sun block you would want to look for those ingredients. Also knowing what that physical sun block is better is important. This is because you would want to find it over chemical sun block.
In our experiment, we will be testing to see which brand of sun block at SPF 50 will protect a sun strip over another sun strip.

A benefit of fake tanning in tanning beds is that it can be a source of vitamin D which is prevalent in the sun’s rays (Should Tanning Beds Be Banned?). By using skin protectant and eye safety glasses tanning beds can add value to specific individuals. People who use tanning beds regularly, wear eye protectant and the specific sun lotion made for tanning beds so they will not be as exposed to these harmful effects.

Tanning can be harsh to your skin. The light coming from the sun contains different wavelengths of ultra violet (UV) waves. The two types of waves concerned about are UVA rays and UVB rays. UVA rays are long waves that cause more damage than a UVB ray. UVA rays penetrate deeper into your skin and cause tanning (“The Dangers of”). More and more exposure to UVA rays can cause permanent damage ...
Tanning affects the human skin through ultraviolet radiation, part of the spectrum of light that omits from the sun to the surface of the earth. Ultraviolet A rays are the longer ultraviolet rays that are projected, and these rays penetrate deep into the layers of skin, causing a tanning effect (Harvard Women's Health Watch, 2). It does this by penetrating into the lower layers of skin, or the epidermis, and triggering cells known as melanocytes to make melanin, the brown pigment that causes tanning (Hyde, Patrice, MD, 1). They account for most of the ultraviolet components emitted by lamps in tanning beds, because they are associated with an almost immediate tanning effect (Brady, Mary S, 2). The shorter rays are ultraviolet B rays, and these rays only reach the outer superficial skin cell layer, also known as the epidermis (Harvard Women's Health Watch, 2). UVB rays, therefore, are the actual cause of sunbur...
Sun shine contain ultraviolet ray which can cause the sunburn or even skin cancer. According to Cancer Council in Australia, Australia has highest incident rate of skin cancer in the world. More than 430000 Australians are diagnosed with skin cancer each year. There are approximately 60 percent of people who have got skin cancer will survive greater than five years after they diagnosis (Cancer Council Australia, 2014). In order to protect people under the sun, the sun protective behaviour is significant necessary.
Melanoma skin cancer has multiple causes. The biggest and newest cause of melanoma skin cancer is a result of tanning in salon tanning beds. As said by Zoe D. Draelos, MD, FAAD, consulting professor, Duke University School of Medicine, Durham, NC “What they may not realize is that no matter whether you tan or burn, a tan from the sun or tanning beds damages the skin and may cause wrinkles, age spots, and skin cancer.” Now more than ever every day routines consist of going to the tanning salon. Adults are beginning to take their children to start tanning at young ages exposing them to the UV radiation that causes melanoma.
Most forms of skin cancer are found on areas of the body that experience constant exposure to sunlight. The ultraviolet rays in sunlight are one main cause of skin cancer, but artificial sources of UV rays have also been proven to be a contributing factor.
UV radiation causes significant damage to human skin, in the form of sunburns, aging, skin cancer, and nonmelanoma tumors. Human skin damage is primarily a result of tanning. The
Indoor Tanning beds are controversial and not without risk. The positives and negitives should be told straight up when going to a tanning salon. The risk of developing melanoma skin cancer from over exposure to UVA and UVB radiation has been proven and well documented by the medical field and research. There are a few benefits of using indoor tanning beds such as a positive mood boost, healing of some types of skin disorders and in the production of vitamin D. One must be educated about the use of indoor tanning before deciding to indulge and weigh the risks and benefits before making the decision to go tanning long term.
Skin Cancer is caused by hereditary factors, overexposure to the sun, and weak immune systems. (“Skin Cancer” infotrac.com) One reason people tend to get skin cancer is when someone in your family has passed their genes down to you, known as hereditary. Normally hereditary is one of the causes in the development of melanoma. For all types of skin cancers, overexposure of the skin to UV radiation in sunlight is the most frequently blamed source of skin cancer. “Research suggests that sunburns received early in one’s childhood can lead to skin cancer later in life” (“Skin Cancer” infotrac.com). For example, when someone gets sunburned, you usually don’t know till ten to twenty years after and that’s why people don’t get skin cancer till they reach their twenties.
The major environmental risk factor for melanoma is overexposure to ultraviolet (UV) radiation from the sun. People who have fair skin that burns or freckles easily need to be especially careful in the sun as protecting yourself against UV overexposure is an important way you can help reduce your risk of developing melanoma.
Probably the most commonly used word by your dermatologist, your beautician, your pharmacist or just the girl next door, and for a good reason. The sun’s damaging UV rays can single-handedly destroy your skin over time and in some cases even cause irreparable damage. It will burn your skin, dry it out, destroy collagen fibers and predispose you to cancer. Whether it’s a scorching sun or not, whether you are outdoors or not, sunscreen is an everyday must-wear. You have a choice.
We need the sun for everything; food, transportation, education, and just to live. The sun negatively affects us in our daily lives because our skin is sensitive to the sun. This means that we are prone to burn. A way to protect our skin is with sunscreen. The short-term effect of not wearing sunscreen when exposed to the sun is you can get a painful rash or peeling of skin can occur. Long-term effects of not protecting yourself from the sun can be that it changes your DNA or gives you skin cancer. It changes your DNA by radiation smashing into you skin. The reason why this is so dangerous is because the DNA will now instruct the skin to fix itself because of the radiation, but the instructions would have been changed. It can also speed up
