Overexposure to the sun is damaging UV radiation; it can cause diseases and burns. There are so many new types of skin cancer than the any other types of cancers. Sunscreen is a current creation that engrosses or reflects the sun’s UV light. Sunscreen is helping to defend against sunburn and skin cancer.
It does not matter where we all are; we all come into contact with the sun’s rays. Whether we are outside going for a run or watching a soccer game, our skin is at risk by the sun. It is well known that solar radiation is damaging our skin; we protect ourselves from the sun’s force by wearing hats, sunglasses, or high-SPF sunscreens. Wearing sunscreen is protecting our skin from the skin? How long will the sunscreens last? Sunscreen products normally include active ingredients to protect human skin from UV energy, such as organic mixtures that attract UV rays and non-living compounds which act as chemical or physical filters avoiding or reducing UV penetration. Extra ingredients commonly present in about all commercial products include preservers, adjuvants, lotions, and antioxidants. Some reports discovered that sunscreen elements promote virus-related diseases in bacteria.
Thus, the connection of eco-compatible sunscreens can protect human skin from UV radiation. Our judgment is providing new understandings on the effects of sunscreens on our lives and encourages the use of eco-compatible sun care products; safe for every individual and the environment we are living. We decided to choose three different brands of sunscreens categorized by a high sun protection of SPF 50+. Sunscreen (I) has SPF 50+, this product has TiO2, Octocrylene, bis-ethylhexyloxyphenol, benzyl benzoate and butyl methoxydibenzoylmethane. Sunscreen (II) SPF 50 has benzophenone-3, butyl methoxydibenzoylmethane, homosalate, octyl salicylate, preservatives and octocrylene. Lastly, we choose a sunscreen (III) SPF 40, has ethylhexyl triazone, diethyl amino hydroxybenzoyl hexyl benzoate, methylene bis-benzotriazolyl tetramethylbutylphenol and the protective sorbic acid.
Different varieties of sunscreen include different recipes of active ingredients that can compose to reduce the impact of risky rays of light from the sun. Some of these materials will affect the UV light while others will absorb it. Most sunscreens work by either an organic chemical compound that attracts ultraviolet light, or an opaque material that redirects the light or a mixture of both. Sunscreen stains the light from the sun not many of it spreads to the deeper layers of your skin. As its materials attract UV energy, sunscreens start to fail and lose effectiveness. Sunscreen should be applied before the sun exposure to the skin.
To be successful in avoiding skin cancer and sunburn, sunscreen should be applied every two hours regardless of their assigned SPF. The higher the SPF, the more safety a sunscreen will offer against UVB radiation and sunburn. For instance, if it takes 20 minutes for our defenseless skin to start turning red, using an SPF 15 sunscreens hypothetically prevents 15 times longer-about five hours. SPF 50+ blocks 99%, SPF 50 blocks 98% and SPF 40 blocks 97%.
Randomly chose three volunteers to participate in this experiment. Volunteers had to have a positive background of sunburn in the past and to have at least 15 days of vacation in sunny areas for the next 2 months. Volunteers were randomly given to receive an SPF 50+, SPF 50 or SPF 40 sunscreens.
The three sunscreens were made with the same chemical absorbents, but the SPF 40 sunscreens contained a greater concentration of substances. This picture shows what happens to our skin sunburn Black squares signify the sun protection factor SPF 50, black circle signify SPF 40 Participants. There is serious need for increasing cosmetic products to protect every individual’s skin from the risks of solar radiation. The sun is an important when it comes to good health.
Ideal physical and mental happiness requires some exposure to the sun. Ultraviolet light allows the body to create Vitamin D, a vital material that works against the formation of tumors and helps in the absorption of calcium. Not only does sunlight support our physical protections against disease, but it also improves our mental, emotional protections against depression and exhaustion. A number of researched the effect of UV filters and preservatives on a variety of our lives. There are no studies judging contextually the effects of sunscreens on human skin cells.
We researched the defensive efficacy of two widely used sunscreens I, II including organic and inorganic filters previously reported affecting our cells and sunscreen III materials have been eco-friendly. With all the sunscreens we testes here, only sunscreens I, sunscreens III are concealing both UVA and UVB. Even though, sunscreen II is considered by a limited UVA absorption, all the three sunscreens examined were similarly effective. Sunscreen I had a smaller impact than Sunscreen II, affecting the growth of one third of the beginnings of all concentrations.
The effects of Sunscreen III were blurry from the control after one?day of treatment, the lack of negative effects on the early development. Research shows that the three examined sunscreens have a similar effectiveness in defending human fibroblasts from UVA radiation. The defensive outcome of sunscreen use against skin cancer has not been established in the general population, but there are forceful data that show a strong relationship between duration of sun exposure and skin cancer.
