Perbedaan Sunscreen dan Sunblock yang Perlu Anda Tahu

Pengertian dan Manfaat Sunscreen Pengertian sunscreen – Sunscreen adalah lotion pelindung dari sinar matahari yang meyerap ke dalam lapisan teratas kulit untuk menyerap sinar matahari yang sudah sempat masuk ke dalam kulit Biasanya sunscreen dapat melindungi kulit dari sinar UVB saja Sinar UVB ini dapat menyebabkan kulit terbakar dan perih.

cell carcinoma two types of skin cancer There is little evidence that it is effective in preventing basal cell carcinoma A 2013 study concluded that the diligent everyday application of sunscreen could slow or temporarily prevent the development of wrinkles and sagging skin The study involved 900 white people in Australia and required some of them to apply a broadspectrum sunscreen every day for four and a half years It found that pe Potential risks In 2009 the Therapeutic Goods Administration of Australia updated a review of sunscreen safety studies and concluded “The potential for titanium dioxide (TiO2) and zinc oxide (ZnO) nanoparticles in sunscreens to cause adverse effects depend primarily upon the ability of the nanoparticles to reach viable skin cells To date the current weight of evidence suggests that TiO2 and ZnO nanoparticles do not reach viable skin cells” Sunscreen ingredients typically undergo extensive review by gove Sun protection factor and labeling The sun protection factor (SPF rating introduced in 1974) is a measure of the fraction of sunburnproducing UV rays that reach the skin For example “SPF 15” means that 1⁄15 of the burning radiation will reach the skin assuming sunscreen is applied evenly at a thick dosage of 2 milligrams per square centimeter (mg/cm2) It is important to note that sunscreens with higher SPF do not last or remain effective on the skin any longer than lower SPF and must be continually reapplied as directed Sunblock Sunblock typically refers to opaque sunscreen that is effective at blocking both UVA and UVB rays and uses a heavy carrier oil to resist being washed off Titanium dioxide and zinc oxideare two minerals that are used in sunblock The use of the word “sunblock” in the marketing of sunscreens is controversial Since 2013 the FDA has banned such use because it can lead consumers to overestimate the effectiveness of products so labeledNonetheless many consumers use the words sunblock and sunsc In addition to moisturizersand other inactive ingredients sunscreens contain one or more of the following active ingredients which are either organic or mineral in nature 1 Organic chemicalcompounds that absorb ultraviolet light 2 Inorganic particulates that reflect scatter and absorb UV light (such as titanium dioxide zinc oxide or a combination of both) 3 Organic particulates that mostly absorb UV light like organic chemical compounds but contain multiple chromophores that reflect and scatter a fraction of light like inorganic particulates An example is Tinosorb M The mode of action is about 90% by absorption and 10% by scattering The principal active ingredients in sunscreens are usually aromatic molecules conjugated with carbonyl groups This general structure allows the molecule to absorb highenergy ultraviolet rays and release the energy as lowerenergy rays thereby preventing the skindamaging ultraviolet rays from reaching the skin So upon exposure to UV It is known that SPF is affected by not only the choice of active ingredients and the percentage of active ingredients but also the formulation of the vehicle/base Final SPF is also impacted by the distribution of active ingredients in the sunscreen how evenly the sunscreen applies on the skin how well it dries down on the skin and the pH value of the product among other factors Changing any inactive ingredient may potentially alter a sunscreen&#39s SPF When combined with UV filters added antioxidants can work synergistically to affect the overall SPF value positively Furthermore adding antioxidants to sunscreen can amplify its ability to reduce markers of extrinsic photoaging grant better protection from UV induced pigment formation mitigate skin lipid peroxidation improve the photostability of the active ingredients and neutralize reactive oxygen species formed by irradiated photocatalysts (eg uncoated TiO₂) thus enhancing the efficiency and safety of sunscreens Compar SPF 30 or above must be used to effectively prevent UV rays from damaging skin cells This is the amount that is recommended to prevent against skin cancer Sunscreen must also be applied thoroughly and reapplied during the day especially after being in the water Special attention should be paid to areas like the ears and nose which are common spots of skin cancer Ask your dermatologist about what sunscreen is best to use for your specific skin type The dose used in FDA sunscreen testing is 2 mg/cm2 of exposed skin If one assumes an “average” adult build of height 5 ft 4 in (163 cm) and weight 150 lb (68 kg) with a 32inch (82cm) waist that adult wearing a bathing suit covering the groin area should apply approximately 30 g (or 30 ml approximately 1 oz) evenly to the uncovered body area This can be more easily thought of as a “golf ball” size amount of product per body or at least six teaspoonfuls Larger or smaller individuals should scale these quantities accordinglyC Certain sunscreens in water under ultraviolet light can increase the production of hydrogen peroxide which damages phytoplankton A 2002 study suggests that sunscreen causes an increase in virus abundance in seawater leading to poor marine environment health similar to that of other pollutants A 2008 study that tested different sunscreen brands protective factors and concentrations found that they all caused bleaching on hard corals and the rate of beaching increased with increased quantity of sunscreen Of the compounds found in sunscreen that were tested separately “butylparaben ethylhexylmethoxycinnamate benzophenone3 and 4methylbenzylidene camphor caused complete bleaching even at very low concentrations” Media reports link oxybenzone in sunscreens to coral bleaching although some environmental experts dispute the claim A 2015 study published in the Archives of Environmental Contamination and Toxicology linked oxybenzone to effects on cell culture experiments and j Early civilizations used a variety of plant products to help protect the skin from sun damage For example ancient Greeks used olive oil for this purpose and ancient Egyptians used extracts of rice jasmine and lupine plants whose products are still used in skin care today Zinc oxide paste has also been popular for skin protection for thousands of years Among the nomadic seagoing SamaBajau people of the Philippines Malaysia and Indonesia a common type of sun protection was a paste called borak or burak which was made from water weeds rice and spices It was used most commonly by women to protect the face and exposed skin areas from the harsh tropical sun at sea In Myanmar thanaka a yellowwhite cosmetic paste made of ground bark is traditionally used for sun protection “The first ultraviolet B filters were produced in 1928” Followed by the first sunscreen invented in Australia by chemist HA Milton Blake in 1932 formulating with the UV filter &#39salol (Phenyl salic New products are in development such as sunscreens based on bioadhesivenanoparticles These function by encapsulating commercially used UV filters while being not only adherent to the skin but also nonpenetrant This strategy inhibits primary UVinduced damage as well as secondary free radicals Also UV filters based on sinapate estersare under study Does it work or not? – illustrated explanation of how UV light is absorbed by chemicals in sunscreen from Wired
