Butterbean sunscreen 20SPF 全天然防晒。一共只有6种成分。 Ingredient: beeswax, shea butter, appricot  kernel oil, coconut oil, zinc oxide>100mn 22%, tocopherol(维他命E) Coconut oil. Renowned for its nourishing effects on the skin. The antioxidant properties prevent burning, premature aging and oxidative damage. Coconut oil has anti-viral, anti-bacterial and anti-protozoa properties. It also has naturally occurring sun protection. Zinc Oxide.A micronized powder from the earth. Zinc is used in sunscreens to provide a physical barrier between the suns rays and your skin. We use powdered zinc oxide and add it to the oils over a very low heat. The zinc oxide used at Butterbean is non-nano meaning the particles are large enough not to get into the blood stream (read more here). Shea butter. Extracted from the nut of the Karate Tree or, “The Tree of Life". This Shea butter is raw and unrefined. It is produced in the traditional way in Uganda by village women. The women scoop the oil into gourds and the gourds are packed and shipped. Shea butter is high in unsaponifiables, antioxidants and cinneamic acid, a natural sunscreen. Shea Butter also contains Vitamins A, E and F. Vitamins A and E sooth the skin as well as provide collagen which has a recognized effect against skin aging. Vitamin F has essential fatty acids that restore damaged skin. Beeswax. Seals in moisture on the skin and helps to make the sunscreen more water resistant. It imparts a sweet fragrance as well. Our beeswax is sourced locally from a beekeeper named Brian. He has been keeping bees since 1992. Apricot Kernel Oil. A very mild and non-greasy oil. It is gentle for sensitive baby skin and great for any skin type. Apricot kernel oil is high in vitamins E, A and C. It is also rich in essential fatty acids like oleic and linoleic acid. The source company has a pure-as-can-be ingredient standard. Every essential oil must pass a battery of tests to ensure its authenticity, quality and purity. The extraction method does not include solvent, hexane, or alcohol extraction and the result is an oil that is as pure as it can be! - See more at: http://www.butterbeansunscreen.com/ingredients.html#sthash.iTvfYYwB.dpuf Vitamin E. An antioxidant that scavenges for free radicals in tissues. It incorporates into the cell membrane and protects the cell from oxidative damage. Vitamin E is a strong moisturizer. Vitamin E works as a natural preservative to extend the shelf life of our products.  - See more at: http://www.butterbeansunscreen.com/ingredients.html#sthash.iTvfYYwB.dpuf 这家还有喷的防晒，宝宝大人都能用，在www.ewg.org 上的score 是0， 是最好的天然的防晒。 UvA Protection  EXCELLENT UvB Protection  EXCELLENT Mineral vs Chemical sunscreensButterbean sunscreen contains zinc oxide as the primary sun blocking ingredient. Zinc oxide is a mineral that works as a physical barrier where it sits on top of the skin and scatters and absorbs ultraviolet rays from the body. Zinc oxide is photo stable which means the sunscreen will not loose its effectiveness an hour after it is applied. It is not absorbed into the skin. Butterbean also contains organic ingredients. The Coconut and Shea butter oils are certified organic. The Apricot kernel oil is sourced from Aura Cacia, a company that has a well earth sustainability program. Zinc oxide does not carry an organic certification, however it is a natural mineral. Chemical sunscreens absorb into the skin to impart protection. This is the reason that chemical sunscreens must be soaked in for 15 minutes before swimming. There are often multiple chemicals included in order to provide a full spectrum protection. One active ingredient in many chemical sunscreens is oxybenzone. The US Center for Disease Control found that 97% of Americans have this chemical in their blood. This ingredient has been proven to disrupt normal hormone functions and should not be used on babies or children as it may disrupt their developing systems. Additional chemicals in sunscreens break down into free radicals or carcinogens. The chemicals do not just sit on top of the skin, but are absorbed and enter the body. The Environmental Working Group, a non-profit, recommends to avoid spray sunscreens entirely. The ingredients in chemical sunscreens are not meant to be inhaled and can be extremely hazardous. About SPF:SPF stands for Sunburn Protection Factor. There are two categories of UV light: UVA and UVB. UVA causes aging and UVB causes burns. SPF numbers are for UVB rays only. PPD, which stands for persistent pigment darkening, is the term used to measure UVA.  SPF helps to prevent sunburns and PPD guards against photoaging. It is important to have a broad spectrum sunscreen to protect against both types of UV rays. Sunscreen with a UV protection above 30 can give a false sense of security since these numbers do not offer significantly more protection from the suns rays. So here's how SPF numbers work. The idea is that if it takes, say, 10 minutes of sun exposure to cause a burn, an SPF15 will allow you to be in the sun for 10 minutes X 15 or 150 minutes without burning. This equation is non-linear. An SPF70 will not give protection for 700 minutes. An SPF15 absorbs 93.3 percent of UVB rays. An SPF30 absorbs 96.7 percent. Even though the SPF number doubled, the absorption has increased only slightly. An SPF50 absorbs 98 percent. As you can see, once an SPF30 is reached protection does not increase dramatically. The FDA has stated that any sunscreens labeled higher than SPF30+ are misbranded. Butterbean sunscreen has an approximate SPF of 20. This is based on the percentage of zinc oxide used (20%) and takes into account the way that non-nano zinc oxide behaves in a matrix. Coconut oil and Shea butter have a naturally occurring SPF delivering extra protection. Sunscreen should be re-applied at least every 2 hours and after swimming. Other measures should be taken to limit sun exposure such as: wear protective clothing such as rash guards and hats stay in the shade as much as possible avoid the hours between 10am and 4pm when the suns most intense UV rays are shinning avoid reflective surfaces such as water, sand or pavement - See more at: http://www.butterbeansunscreen.com/about-spf.html#sthash.ieLs38NZ.dpuf - See more at: http://www.butterbeansunscreen.com/mineral-vs-chemical-sunscreens.html#sthash.5PM4MnWE.dpuf [size=15.5555562973022px] 快点看看你们的防晒有没有有害的成分， 我最近扔了三支几乎没怎样用过的防晒，一看怪不得脸好像很敏感原来我的防晒含有 Chemical EWG Hazard Score Use in U.S. sunscreens Skin Penetration Hormone disruption Skin Allergy Other concerns References UV filters with higher toxicity concerns Oxybenzone 8 Widespread Detected in nearly every American; found in mother’s milk; 1-to-9% skin penetration in lab studies Acts like estrogen in the body; alters sperm production in animals; associated with endometriosis in women Relatively high rates of skin allergy Janjua 2004, Janjua 2008, Sarveiya 2004, Gonzalez 2006, Rodriguez 2006, Krause 2012 Octinoxate (Octylmethoxycinnamate) 6 Widespread Found in mothers’ milk; less than 1% skin penetration in human and laboratory studies Hormone-like activity; reproductive system, thyroid and behavioral alterations in animal studies Moderate rates of skin allergy Krause 2012, Sarveiya 2004, Rodriguez, 2006, Klinubol 2008 UV filters with moderate toxicity concerns Homosalate 4 Widespread Found in mothers’ milk; skin penetration less than 1%  in human and laboratory studies Disrupts estrogen, androgen and progesterone Toxic breakdown products Krause 2012, Sarveiya 2004, SCCNFP 2006 Octisalate 3 Widespread; stabilizes avobenzone Skin penetration in lab studies Rarely reported skin allergy Walters 1997, Shaw 2006 Singh 2007 Octocrylene 3 Widespread Found in mothers’ milk; skin penetration in lab studies Relatively high rates of skin allergy Krause 2012, Bryden 2006, Hayden 2005 UV filters with lower toxicity concerns Titanium Dioxide 2 (topical use), 6 (powder or spray) Widespread No finding of skin penetration No evidence of hormone disruption None Inhalation concerns Gamer 2006, Nohynek 2007, Wu 2009, Sadrieh 2010, Takeda 2009, Shimizu 2009, Park 2009, IARC 2006b Zinc Oxide 2 (topical use), 4 (powder or spray) Widespread; excellent UVA protection Less than 0.01% skin penetration in human volunteers No evidence of hormone disruption None Inhalation concerns Gulson 2012, Sayes 2007, Nohynek 2007, SCCS 2012 Avobenzone 2 Widespread; best UVA protection of chemical filters Very limited skin penetration No evidence of hormone disruption Relatively high rates of skin allergy Klinubol 2008, Bryden 2006, Hayden 2005, Montenegro 2008 Mexoryl SX 2 Uncommon; pending FDA approval; offers good, stable UVA protection Less than 0.16% penetrated the skin of human volunteers No evidence of hormone disruption Skin allergy is rare Benech-Kieffer 2003, Fourtanier2008 6 other ingredients approved in the U.S. are rarely used in sunscreens: benzophenone-4, benzophenone-8, menthyl anthranilate, PABA, Padimate O, and trolamine salicylate

大家可以上www.ewg.com 这个网有所有化妆品，护肤品，洗发水。什么东西都有， 它根据产品的成分来score它的危害性，而我分享的这个防晒虽然我还没用过，但是我看它的成分真的又简单有天然，比其他大牌子还是天然的防晒还是更胜一筹我觉得在防晒效果方面。它是个美国网，我住在加拿大，所以要买还是要上网买，而且这个是make fresh to order。 我不是卖广告，只是觉得这个真心好，我之前买的OMBREELLE 防晒擦得我脸真的好像刺痒过敏才开始研究防晒。我之前找资料如果每天坚持擦防晒，到50岁的时候比同龄人年轻13岁，不管真还是假，紫外线还是会破坏皮肤镇曾胶原蛋白，现在不擦防晒看不出来皮肤有什么不一样，但是我觉得20年后就看的出来了。 我觉得擦多少保养品之前还是把防晒做最好！
