Most Effective Sunscreen

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.

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.

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

Whether swimming at the beach, picnicking at a park, or snowboarding in the mountains, our skin is continuously exposed to the sun’s ultraviolet rays as we go about our daily lives. The skin is beneficial as it protects our body from the outside elements including keeping out wind and water, dirt and dust, and all types of germs (Claybourne; 56). The topic of my experiment is to determine which SPF strength of sunscreen - SPF 30, SPF 50 or SPF 70 - is the most effective in blocking out the sun’s UV radiation. The purpose of this investigation is to observe, compare and determine whether the SPF label on sunscreen bottles are really effective in blocking out the amount of the sun’s UV rays, or if it is just a marketing gimmick to sell more products. This investigation benefits society because knowing which strength of SPF is the most effective in protecting against UV rays is useful to know when shopping for sunscreen, especially for those who spend a lot of time outdoors.

Since UV radiation is so damaging, always wear UV-blocking sunglasses, and start wearing proper eye protection at an early age.

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.

Since its inception in 1979, The Skin Cancer Foundation has always recommended using sunscreen with an SPF of at least 15 or higher as one important part of a complete sun protection regimen. Other prevention tips include the following: seek the shade, cover up, keep newborns out of the sun, examine your skin, and avoid tannin/ using UV tanning beds. It is also recommended you see you physician annually for a professional skin

The sun is an amazing creation, it gives off vitamin C while making people feel warm and happy. In addition to trying to achieve that beautiful tan there are many reasons why people love to bath in the sun but plenty more reasons on why people should protect themselves from the sun. Overexposure to the sun could cause severe permanent damage to the skin, including premature aging and the worst of all skin cancer. The sun releases UV rays (ultraviolet radiation) which damages DNA and disables protective tumor suppressor genes in the epidermal cells, causing the skin cells to rapidly multiply forming tumors.

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).

Adequate coverage. Using sunscreen can only protect the areas of the body where it has been applied. Trying to make sure that happens by yourself isn't adequate. You always need to have someone help you with hard-to-reach places such as the middle of your back and mid-shoulders. If it is not feasible to have someone help you apply, then make sure to use a mirror to maximize your

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.

Skin disease is an anomalous development of skin cells, there are three sorts of skin growths: Basal cell is a tumor that develops on various parts of your body that get heaps of sun. It can spread to different parts of your body too. Squamous cell malignancy is the second most basic skin disease. It is normally found in zones of the body harmed by UV beams sun and tanning beds. Melanoma is the most genuine skin malignancy it can get into different organs like your eyes, interior organs like your digestion systems. The sun and tanning beds and any UV radiation exposure increase the risk of skin cancer. Half of all newly diagnosed cancers are skin cancer. (Scarlett W. 371). Solar radiation is an

--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.

Every hour at least one American will die of skin cancer caused by exposure to the sun. These statistics are alarming and most people are unaware that the sunshine that we all love so much is in fact a threat to our health and good looks. It is up to us to educate ourselves and our children on the harmful effects of sun exposure on the human body like premature aging, physical damage to the body, and cancerous diseases.
