Essay On Sunscreens

In this experiment, DNA was extracted from human cheek cells using Gatorade, soap solution, and rubbing alcohol. To do this, Gatorade was swished in the subject’s mouth vigorously for 45 seconds, and then added to soap solution and rubbing alcohol. This mixture was left to sit in ice water for two to three minutes. It was hypothesized that when cheek cells were placed into Gatorade, soap solution, and rubbing alcohol, that the DNA would be extracted, forming a stringy substance. This hypothesis was supported by the results of the experiment. After adding the alcohol to the Gatorade and soap solution, a semi-translucent, fibrous substance was formed.

A common challenge that most consumers will face is ineffective sun screens. This has caused many people to begin to experience an increase in cases of skin cancer. The problem is that research has confirmed these challenges. Yet, no one has utilized the latest technology to create a product that will protect consumers and is environmentally friendly. This proposal is focusing on how this kind of merchandise can be marketed to customers to address this underlying need. The expected outcome is that these strategies will help to redefine how firms are delivering this product to cliental.

Thesis statement: Many people do not use sun protection on a daily basis and are unaware of the dangers that can be easily preventive by using sun protection.

UV radiation, such as that from the sun can be very harmful. It has been shown to cause many different mutations within cells, leading to issues for the organism such as death or disease. One of the most prevalent sources of UV radiation for humans is the sun. It’s very important for us to know the extent of cellular damage that can be caused by this radiation, as to know how harmful the sun’s rays are to us as humans. One way that the damage caused by the suns radiation can be tested is through the model organism yeast. For this lab, we exposed two different strains of yeast to UV radiation to test its affects. One strain was able to self-repair, while one was genetically altered so that it could not. Observations were recorded at

You can also find sunscreens with added antioxidants, such as green tea extract, that can further protect your skin from free radical damage caused by the sun and other environmental irritants.

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.

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.

In the United States, more cases of skin cancer have been diagnosed than any other type. It is estimated that about 2 million of these cases arise every year, and can be prevented significantly from utilizing sun protection.

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.

What is DNA? Is it these winding strands that look like ladders or is it what gives a person blonde hair and blue eyes? Actually, DNA is both of these things. DNA is a person’s genetic makeup–their hereditary blueprint passed on by their parents. It is a part of almost every cell in the human body. In each cell, a person’s DNA is the same; it stays the same throughout their lifetime. DNA is found in skin tissue, sweat, bone, the root and shaft of hair, earwax, mucus, urine, semen, and vaginal or rectal cells. The DNA found in a person’s saliva is the same as the DNA found in their blood. Parts of the DNA determine our physical characteristics, such as eye and hair color, height, and bone structure, but the

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.

Science has improved miraculously in the past few decades. So much that we are now able to re create human skin cells and test products like cosmetics on it.

However it is a known carcinogen and therefore alternatives have been developed. These, for instance gelred, can be used without the use of UV lighting. However they are often a lot more expensive.
