  • Sunscreen Faqs
    Sunscreen FAQs What type of sunscreen should I use? There are two main types of sunscreen ingredients: physical sun blockers and chemical sunscreens. Physical sunscreens prevent ultraviolet light from reaching your skin, and contain either zinc oxide or titanium dioxide. Physical sunscreens protect against UVA and UVB damage. Physical sunscreens are preferred for patients with sensitive skin or children. Chemical sunscreens rely on an interaction between the sun and the chemical to protect your skin. Examples of such chemicals are avobenzone, octinoxate, homosalate, padimate O, and many others. Chemical sunscreens can protect against UVA, UVB, or both types of damage, depending on which ingredient is used. Read the label to ensure coverage for both UVA and UVB exposure. There are new ingredients being developed that take chemical sunscreens and stabilize them to prolong their activity (i.e., Helioplex, Mexoryl). Does the SPF really matter? In laboratory testing, there are minor differences between SPF 15 and SPF 30 or greater products. However, that data is based on using 1 oz. (30 gm.) of sunscreen for each full body application (the size of a shot glass). Most people use far less in real-life settings. For that reason, we recommend an SPF of at least 30. It is common to find good sunscreens with SPF ranging from 45-70. To maintain protection, reapply sunscreen every 1-3 hours, depending on sweating, water exposure, and sun intensity. Is sunscreen alone enough to protect my skin in the sun? In some cases, yes. However, if you are in the sun for longer periods on a regular basis (such as gardening, golfing, boating, sports), it may be better to add sun protective clothing or habits.

  • Which Sunscreen Provides the Most Effective Protection Against UV Rays?
    Which Sunscreen Provides the Most Effective Protection Against UV Rays? Haven Simmons Background information ● Ultraviolet (UV) rays are invisible rays that are part of the energy that comes from the sun. A common danger of UV rays is sunburns. Prolonged exposure to UV radiation may increase the risk of skin cancer. ● Sunscreen, also known as sunblock, is a lotion, spray, gel, foam, stick or other product that absorbs or reflects some of the sun's ultraviolet radiation and helps protect against sunburn. ● SPF stands for sun protection factor. It is a measurement of the sunscreen’s ability to protect skin from UVB rays. These rays damage the outermost layers of the skin. ● The best SPFs to use is 30 and below. Anything above 30 can sometimes be ineffective ● Some sprays have alcohol that may affect the skin or may not give enough protection. It is better to use if you play sports or do any physical activities outside. Lotions have better coverage since you have to rub it in. Lotions are very effective in preventing skin cell cancers. Background Information (Continued) ● Chemical based sunscreen absorbs the UV rays so your skin doesn't. Natural based sunscreen scatters the UV rays away from the skin. Chemical based sunscreen breaks down the UV rays easily but can irritate your skin. Natural doesn't have as good an effect as chemical but is best used for people with sensitive skin. ● Main active ingredients include: zinc oxide, titanium dioxide, and octinoxate. ● Zinc oxide is one of the most effective ingredients to have in sunscreen.

  • Almost Summer Sun Protection Edition: Sunscreen 2019, Sunscreen Danger?, UPF Clothing
    © Take 3 – Practical Practice Pointers June 3, 2019 Edition Almost Summer Sun Protection Edition: Sunscreen 2019, Sunscreen Danger?, UPF Clothing From the Consumer Reports and Caveat Emptor 2019 1) Sunscreen 2019: Not All Sunscreens Deliver Claimed SPF Ultraviolet radiation (UV) exposure is recognized as a major environmental risk factor for both melanoma and keratinocyte cancers. The sun protection factor (SPF) is a relative measure of how long a sunscreen will protect you from UVB rays, which are the chief cause of sunburn and a contributor to skin cancer. Usually the number is explained as the amount of time it takes an individual’s skin to burn when it’s covered in sunscreen compared with when it’s not. For example, assuming you apply—and reapply—the sunscreen correctly, if you’d normally burn after 20 minutes in the sun an SPF 30 protects for about 10 hours. SPF calculations do not apply to UVA rays, which can tan and age skin and also trigger skin cancer. Thus the need for a broad-spectrum sunscreen that provides protection against both types of UV rays. However, no sunscreen blocks 100 percent of UVA or UVB rays. The breakdown: SPF 30 blocks 97 percent of UVB rays, SPF 50 blocks 98 percent, and SPF 100 blocks 99 percent. The Consumer Reports organization yearly tests sunscreens to see how close they approximate their claims. In 2019, of the 82 lotions, sprays, sticks, and lip balms tested, 32 tested at less than half their labeled SPF number. These results aren’t a fluke. Similar patterns have been found in previous years’ sunscreen tests.

  • Alt-Health: Sunscreen, Summer and Skin Cancer
    Alt-Health: Sunscreen, Summer and Skin Cancer Every time I research a health topic, I uncover something that surprises the crap out of me. I assumed that sunscreen protects us from the damaging effects of the sun. Turns out the opposite may be true — cases of skin cancer have actually increased since its introduction to the general market. The ancient Egyptians used plant extracts to protect against sun damage. Zinc oxide paste has been applied to noses for thousands of years. But it wasn’t until the late 1920s that inventors began producing synthetic commercial sunscreens. One of the first was invented in 1938 by Franz Greiter, the man who also invented SPF (sun protection factor.) He called his formula “Glacier Cream.” It had an SPF of 2. In 1944, Benjamin Green gave us Red Vet Pet, a sticky and largely ineffectual substance that was supplied to GIs in WWII. In 1950, Coppertone improved and reintroduced Red Vet Pet to the public as Coppertone Girl and Bain de Soleil. The first Coppertone ads featured a 4-year-old girl with her lips pursed in surprise as a cocker spaniel pulled her swimsuit down, revealing a pure white bottom in contrast to a burnished brown tan. “Don’t be a paleface!” the ad teases. It promises “a magic ingredient that screens out harmful burning sun rays.” People took this invitation at its word. In 2011 the US Food and Drug Administration finally released standards for sunscreen labels. By now it was known that sunscreen was not the protective panacea it had been heralded to be.

SARAH MATLACK FOOD & DRUG LAW WINTER 2009 Sarah Matlack Food & Drug Law, Winter 2009 ABSTRACT: On August 27, 2007 the FDA published a Proposed Amendment to the Final Monograph for Over-the-Counter Sunscreen Drug Products. The proposed regulations marks major progress in the regulation of sunscreen products, because it includes, for the first time, comprehensive regulations addressing testing and labeling standards for both UVB and UVA regulation. Developing a monograph for sunscreen products, however, has been an arduous administrative process that has spanned over 30 years and produced significant criticism of the FDA. This article examines the regulation of sunscreen products in light of cultural and scientific developments that governed the rise and revolution of the sunscreen industry arguing that, for the most part, FDA has responded with impressive flexibility and attention to dynamic technological advancements, transformation of consumer expectations, and uncertain science.

  • Facts About Sun Protection
    Lowe Plastic Surgery (LPS) Dr. Lowe’s Facts about Sun Protection Why should I block out the sun, isn’t good for you? The sun has many benefits, but the sun has many more negatives than positives. The sun will not make your skin look younger; to the contrary, consistent sun exposure makes skin look prematurely old. Many of the harmful effects of sun are not immediate. Sun exposure or artificial sun exposure (tanning beds) significantly increase the risk of skin cancers that include: basal cell carcinoma, squamous cell carcinoma, and melanoma. Patients are not only at risk right now, but in the future. Many of the harmful effects of over-exposure to sun are not reversible and can be deadly. Certain skin types such as light or pale skin are at higher risk of developing sin cancer. Some patients have genetic traits that almost guarantee a deadly skin cancer with over-exposure. Skin cancers result in deforming scars and in some cases the cancer may be deadly! Can I really control the sun? Board certified Dermatologists and Plastic Surgeons routinely give recommendations to patients on skin care and protection. For young patients it might be controlling acne or skin texture. For older patients it is usually about reversing the effects of damaging sun. Suns exposure is one of the few things that every patient with limited resources can control. It is not easy to avoid the sun particularly when you are young and involved in a great deal of outdoor activities. Nevertheless, the fact is the sun and sun tanning will make you look older than you should either now or in the future.
