He helped develop a sun protective formula called ‘Red Vet Pet.’ Soldiers used this petroleum-based, sticky red ‘goo’ to protect themselves from the South Pacific sun. In 1944, Green used his invention as the basis for Coppertone Suntan Cream - the first consumer suncare product in the USA. The more user-friendly mixture, with coca butter and jasmine, concocted by Green on his wife’s stove and tested on his own bald head, was created for his customers in Miami Beach. Coppertone®, the leader in sun protection, has come a long way since Green’s first homemade concoction. In 1957, Plough, Inc, (part of the Schering-Plough Corporation since 1971), acquired what was then known as the Coppertone Sales Corporation. In 1971 the company opened the Coppertone Solar Research Center in Memphis, Tennessee. Today, the Center is one of the world’s largest state-of-the art facilities for testing the efficacy of a wide-range of suncare products to protect and enhance the skin. WHO IS THE COPPERTONE BABY? In 1959, a 3-year-old girl in pig-tails named Cheri Brand posed for a family snapshot in the backyard of her Bronxville, NY home and soon became Little Miss Coppertone, a symbol of summer and poster-girl for the long-running Coppertone sunscreen ad campaign whose famous slogans proclaim “Don’t be a Paleface!” and “Tan - Don’t Burn.“ Many people believe that Jodie Foster was the original Coppertone girl. That is not true. Foster did, however, get her start in showbiz in a Coppertone suntan-lotion ad in 1965. She was three years old at the time and appeared in the ad as a toddler on a boat accompanied by her family. Images property of Schering-Plough Corporation 13 COPPERTONE NO. 6 The original Coppertone® fragrance was called Coppertone Perfume # 6 (apparently the first 5 iterations were not acceptable); this is similar to how Chanel No. 5 got its name in that Chanel’s first 4 versions were rejected. The Coppertone archives only go back 45 years, but looking back to 1961, we find Coppertone Perfume # 6 was not just used in one product but was already being used in a line of Coppertone products, such as Noskote Ointment for the nose and lips, Coppertone Suncare Crème, Coppertone Oil Aerosol, (yes, Continuous Spray in 1961!!), and even Quick Tan Lotion. The scent of Coppertone® continues to be used today and can be smelled in all 50 states of the U.S. as well as around the world in Coppertone® products in Brazil, Italy, Dubai, Canada, Mexico, and Japan.

The brand is recognized around the world as a trusted leader with high standards for testing sunscreens and providing quality products. The introduction of SPF labeling followed work done in the early 1970’s by Schering-Plough scientists who developed the basic SPF testing methodology used in the U.S. at the Coppertone Solar Research Center. The testing methods developed by Schering-Plough were presented to and adopted by the FDA and incorporated into the 1978 FDA-proposed sunscreen monograph, forming the basis for the SPF methods used today. In 1977, Coppertone® was the first brand to cite SPF (Sun Protection Factor) on its labels in the U.S. and in 1978, Coppertone® was the first to market an SPF 15 product: Coppertone Super Shade Sunblocking Lotion, SPF 15. Sunscreens have changed in many ways over the years. The biggest change is that now sunscreens protect against both UVA and UVB protection, whereas the very first sunscreens only offered low levels of UVB protection. The development of more advanced sun-protective ingredients, formulations and delivery systems has made newer formulations easier to apply, as opposed to the first sunscreens that were described as sticky and goo-like. Coppertone® makes hundreds of sunscreens including products for the Coppertone Sport, Oil-Free, WaterBabies and Kids lines. Coppertone also has a line of sunless tanning products called CoppertoneMoisture Mist Tan Continuous Spray, a sunless tanning spray that offers an easy way to a natural looking tan with quick application. The Coppertone® Continuous SprayTM line provides durable broad spectrum UVA/UVB protection in a convenient, easy-to-use spray. Coppertone® Quick CoverTM Lotion Sprays combine the convenience of continuous spray with all the benefits of a lotion. 15 GLOSSARY AGE SPOTS The brown or tan spots that appear on exposed areas of the skin can be caused by years of sun exposure. These spots, which can resemble freckles but are larger, range in size from a quarter of an inch to over an inch. The spots are called age spots and sometimes referred to as "senile freckles." Future age spots can be minimized by applying a high-SPF sunscreen, (SPF 15 or higher), whenever outdoors. BASAL CELL CARCINOMA Antioxidants in sunscreens neutralize free radicals, thus protecting skin from being damaged and allowing skin cells to repair themselves (see Free Radicals). The most common form of skin cancer, basal cell carcinoma usually appears as slowgrowing, translucent, raised pearly nodules, which, if untreated, may ulcerate and sometimes bleed. If detected and treated early, there’s a greater than 95% cure rate. AVOBENZONE BENZOPHENONE Avobenzone is a highly effective broad spectrum sunscreen ingredient offering superior protection from UVA rays. There are many ingredients and methods widely available to all manufacturers to photostabilize A class of sunscreen that includes oxybenzone, used in many U.S. products. These help provide UVA and UVB protection and are used in most Coppertone® products. ANTIOXIDANTS 16 Avobenzone. Photostabilized Avobenzone is used in combination with other sunscreen ingredients in many Coppertone® products to provide excellent broad-spectrum protection from UVB and UVA rays. Avobenzone is also known as Parsol® 1789 and butylmethoxydibenzoylmethane. (Parsol® 1789 is a registered trademark of DSM Nutritional Products, Inc.) BROAD SPECTRUM This refers to sunscreen products that contain ingredients to protect against both UVB and UVA rays. Coppertone® products with SPF 15 or more provide broad-spectrum protection against UVB and UVA rays. Some broad spectrum sunscreens contain Parsol® 1789, aka avobenzone to provide extra UVA protection for those who are outdoors for long periods of time or have sun-sensitive skin. DEET Also known as N, N-diethyl-m-toluamide, DEET is the most common active ingredient found in insect repellents today. Coppertone® Bug & Sun, a dual protection insect repellent and sunscreen, contains 10 percent DEET to repel annoying insects for hours. DIHYDROXYCACETONE (DHA) Many products on the market provide the "look" of a tan without sun exposure, and not all are dyes or bronzers. Coppertone® "sun- less" products such as Coppertone® Endless Summer® Moisturizing Self-Tanners contain dihydroxyacetone. This chemical combines with amino acids in the outer layer of the skin to produce a tan color. You control the "tanning" intensity by the frequency of use. With repeated applications, it’s easy to achieve a darker tan. And the tan will not run or wash off. ECAMSULE (also known by its trade name Mexoryl™SX) is an active ingredient patented by L’Oreal® and recently approved by the FDA for use in one product Anthelios® SX daily moisturizing cream SPF 15.* The ingredient, Mexoryl™ SX, claims to be effective against short UVA rays as defined to be 320-340nm. (Anthelios® SX is a registered trademark of LA Roche-Posay Lab. Pharm.) ERYTHEMA Erythema, redness due to sunburn, is a visible sign of skin damage caused by overexposure to the sun’s ultraviolet rays. The amount of sunlight needed to cause minimally perceptible sunburn is known as the minimal erythema dose (MED). FREE RADICALS Molecules with an unpaired electron which makes them highly reactive. Free radicals contribute to short term skin damage, including sunburn, as well as long term damage like skin cancer and photoaging. HELIOPLEX™ is a name trademarked by the makers of Neutrogena® to describe the technology or combination of ingredients Neutrogena uses to photostabilize Avobenzone. In 2006, Helioplex™ can be found in a select number of Neutrogena® suncare products. There are many ingredients and methods widely available to all manufacturers to photostabilize Avobenzone. For more than 5 years, the makers of Coppertone® have been formulating sunscreens with photostabilized Avobenzone. HOMOSALATE Homosalate is a UVB sunscreen ingredient that is often found in products with lower SPF ratings or in combination with other sunscreens in higher-protection products. It is used in some Coppertone® products. HYPOALLERGENIC This classification indicates that a product has been specially formulated and tested to be less likely to cause sensitive/allergic reactions. All Coppertone® Water BABIES® Sunscreen Lotions, and Coppertone Kids® products, as well as Coppertone® Self Tanner products are hypoallergenic. 17 INCIDENTAL SUN EXPOSURE MINIMAL ERYTHEMA DOSE (MED) NON-COMEDOGENIC Incidental sun exposure is the kind of exposure received unintentionally during everyday activities. For the average person, incidental time spent in the sun is projected to account for 80 percent of his or her lifetime exposure. For this reason, dermatologists emphasize the need to protect the skin with clothing or a high-SPF sunscreen (SPF 15 or above) on a daily basis. The skin’s reaction to sun exposure varies according to the individual. Each skin type is able to accept a specific amount of UV rays before burning. The amount of time an individual can stay in the sun before burning reflects the minimal erythema dose (MED). The MED and expected sun exposure, in turn, determines the proper SPF for a skin type. A product that is non-comedogenic will not clog the skin’s pores. Non-comedogenic sunscreen products, especially designed for those who experience frequent or occasional breakouts, include Coppertone® Oil Free products and Coppertone® Oil Free Sunless Tanner Light/Medium and Dark. OCTYL SALICYLATE NANOMETER MELANOMA The most dangerous of all skin cancers, melanoma is characterized by the uncontrolled growth of pigment-producing tanning cells (melanocytes). If detected in the early stages, melanoma can often be treated successfully, but in the later stages it spreads to other organs and can result in death. MEXORYL™ SX See Ecamsule 18 This is the unit used to measure the wavelengths of solar radiation, including the shortest wavelengths, ultraviolet rays, which are responsible for sunburn, photoaging, and certain kinds of cancer. N, N-DIETHYL-M-TOLUAMIDE Also known as DEET, this is the most common active ingredient found in insect repellents today. Coppertone® Bug & Sun, a dual protection insect repellent and sunscreen, contains 10 percent DEET to repel annoying insects for hours. A relative of homosalate, this UVB sunscreen ingredient is used in lower-SPF products or combined with other sunscreen ingredients in products of higher SPF. OTHER INGREDIENTS Suncare products contain other components such as emulsifiers (to facilitate permanent mixing of oil and water in formula) and preservatives (to guard against spoilage). Moisturizers are also a very important part of the formula since they soften skin and help prevent drying. Additionally, many suncare products contain a variety of special ingredi- ents such as vitamin E and aloe. Exotic oils, such as mink, jojoba and coconut, contribute to the cosmetic appeal and feel of a product. OXYBENZONE A common sunscreen used in combination with other sunscreens to provide broad-spectrum protection. OZONE A gas composed of three atoms of oxygen (03), which partially filters out certain wavelengths of ultraviolet radiation before reaching the earth. OZONE LAYER This is the scattered layer of ozone molecules found in the stratosphere, located six to twenty-five miles above the earth’s surface. The ozone layer partially filters out certain wavelengths of UV radiation from the sun, preventing these rays from reaching the earth. PABA-FREE Para-aminobenzoic acid was considered one of the most effective sunscreens for many years, but it is no longer used in Coppertone® products. PABA can stain clothing and sting skin. PADIMATE O A PABA derivative, this water-resistant sunscreen ingredient is sometimes used for UVB protection in U.S. products. (Also called octyl dimethyl PABA.) PHOTOAGING Dermatologists use this term when referring to certain types of sun-induced skin damage. Photoaging is a process that starts in youth, although the more obvious skin changes, such as wrinkles, freckles, leathery texture and loss of elasticity, may not become evident for decades. Using a high-SPF sunscreen (SPF 15 or above) on a regular basis can help protect the skin from further damage. There is also evidence to suggest that the skin has the ability to heal itself if protected, thereby reversing some of the signs of photoaging. PHOTOSENSITIVITY In certain situations, exposure to ultraviolet radiation can cause skin reactions, such as exaggerated sunburn. For example, people who are taking certain antibiotics, tranquilizers, diuretics and other drugs may experience photosensitivity. The skin reaction may consist of swelling, itching, inflammation, or a rash. Some perfumes and citrus oils can also cause phototoxic reactions. Individuals who experience photosensitive reactions are often advised by their physicians to minimize exposure to sunlight, protect the skin with clothing and use a high-SPF broad-spectrum sunscreen (SPF 30, 45 or 50). PHOTOSTABILITY "Photostability" refers to the ability of a sunscreen ingredient to maintain its protective power and not break down during exposure to UV rays. For more than 5 years, the mak- 19 ers of Coppertone® have been formulating sunscreens with photostabilized Avobenzone to provide longer lasting UVA protection.* There are many ingredients and methods widely available to all manufacturers to photostabilize Avobenzone. PROTECTION FACTOR A (PFA) The PFA (protection factor A) method is based on the minimal response dose (MRD), which is the smallest UVA dose that produces a minimal erythema or tanning response. The response is evaluated 22 to 24 hours after exposure, and is stable, reproducible and clinically significant, in that the action spectra for erythema and tanning are similar to those for skin cancer and photoaging. Further, the test is performed using human subjects with skin types I, II and III, who are the individuals who have the greatest need for sun protection. The UVA protection factor, PFA, is the ratio of the MRD for sunscreen-protected skin to that for unprotected skin. 20 SKIN AGING It is important to distinguish between the changes that occur normally with the passage of time from those that are the consequence of sun over exposure. Many skin changes, such as premature wrinkles, leathery skin, some freckles and other dark spots result from chronic unprotected sun exposure. In fact, it is estimated that overexposure to the sun accounts for 80 percent of the effects we call aging skin. Changes that are attributable to aging include increased dryness, decreased sweating, and changes in hair growth and facial contours. The aging process also affects the skin’s ability to protect itself. The rate of cell production and turnover slows down with age making cell repair less effective. The epidermis - the outer layer of the skin - becomes thinner, and melanocytes gradually lose their pigmentproducing ability, thereby reducing the protection they offer the skin. Those who formerly spent a great deal of time in the sun without using sunscreens can prevent further damage by using a high-SPF sunscreen on a regular basis. This action may actually allow the skin to repair some signs of sun-induced damage. Coppertone® Water BABIES®, Coppertone Kids®, Coppertone® Sprectra 3® and Coppertone Sport® products offer effective sun protection and moisturizing agents important for all ages. SQUAMOUS CELL CARCINOMA A common form of skin cancer, squamous cell carcinoma, appears as nodules or red, scaly patches and can metastasize if untreated. While the cure rate is very high if treated early, squamous cell carcinoma can result in death. SUNBLOCK Sunblock is a term generally used to refer to products in the higher SPF (15, 30, 45, 50) categories of protection. No product is a total sunblock. That is why some tanning can occur even when high SPF products are used. All suncare products with SPF values on the label contain sunscreening ingredients for sunburn protection. SUNBURN The most common adverse reaction to the sun is the ordinary sunburn -- also known as erythema. Burns from the sun are induced primarily by UVB radiation. The injury they cause is characterized by delayed redness and swelling followed by tanning and peeling. Sometimes the skin darkens without first reddening, but that does not mean that the damage has not occurred. Chronic sun damage and sunburns especially in the first 18 years of life can result in dry, wrinkled skin and possibly skin cancer in later life. SUN PROTECTION FACTOR (SPF) The Sun Protection Factor (SPF) is a ratio between the ultraviolet dose required to produce minimal erythema reaction (redness) in protected skin (skin with sunscreen) com- pared to unprotected skin (skin without any sunscreen). The SPF number indicates how many times longer a person can stay in the sun before beginning to burn while wearing sun protection than if he or she was not wearing any sunscreen at all. This amount of time varies from one individual to another. For example, Coppertone® SPF 15 lotion allows a person to remain in the sun without burning 15 times longer than if that same person did not use the product. SPF numbers usually range from 2 to 50. Most dermatologists recommend that people use a sunscreen with a SPF of 15 or higher. It should be applied liberally before exposure to the sun and reapplied often. Reapplication is necessary more frequently if the user swims, engages in sustained vigorous activity, perspires heavily or towels off. SUNSCREENS All sun protection products labeled with a SPF of 2 or higher are considered sunscreens. Sunscreen agents absorb, reflect or scatter UV light. Most lotions and oils work by forming a surface layer of sunscreen ingredients on the skin, which absorb the sun’s UV rays exposed before they can penetrate the skin. SUN-EXPOSED AREAS OF THE SKIN Particular areas of the body are more likely to burn due to continued sun exposure than other parts of the body. These include the ears, lips, cheekbone area, nose, top of the head and shoulders. Don’t forget these areas when applying sunscreen. Also, protecting one’s eyes with UV blocking sunglasses is very important since ultraviolet light may damage the eyes, leading to cancer of the eyelids and conjunctiva (the membrane covering the eyeball and lining the lids), as well as to the development of cataracts. 21 SWEATPROOF FORMULA (Ultra Sweatproof) Some products bond to the skin on contact, allowing sunscreens to provide protection despite sweating without leaving a noticeable residue. Sunscreens such as Coppertone Sport® Ultra Sweatproof Dry Lotion allow fitness enthusiasts to enjoy outdoor activities with the confidence that the sunscreen will not leave a greasy residue to affect their grip or run into their eyes and cause stinging. TANNING/BURNING PROCESS When sunlight stimulates the melanocytes, they produce melanin. Melanin is the brown pigment that gives the skin its tanned appearance. The darkening or tanning of the skin caused by melanin is one of nature’s ways of protecting the underlying basal layer form further sun exposure. However, even as this natural process is taking place, sunburn 22 can also occur, causing damage to the epidermis and the dermal layer below that. Sunburn damage occurs before you are able to see or feel it. Frequently, sunburn occurs before tanning. It is not true that a tan will completely protect the skin from burning. TITANIUM DIOXIDE, ZINC OXIDE Ingredients that reflect, absorb and scatter UV rays are called inorganic or "physical" sunscreens. They form protective barriers to UV penetration of the skin and provide UVA and UVB protection. ULTRAVIOLET RADIATION: UVA, UVB, UVC: Ultraviolet (UV) radiation is part of the sun’s spectrum – wavelengths shorter than visible light. Ultraviolet rays are divided into UVA (320-400 nanometers), UVB (290-320 nm) and UVC (<290 nm). The UVA spectrum is further divided into UVA II (320-340nm) and UVA I (340-400nm). UVB rays are the primary cause of sunburning, premature aging of the skin and development of skin cancer. UVA rays are more constant year-round and penetrate deeper into the skin’s layers; UVA rays are also harmful and contribute to burning, premature aging of the skin, and the development of certain forms of skin cancer. UVC rays are blocked by the ozone layer and do not reach the earth’s surface. Tanning beds primarily emit UVA rays. This kind of exposure does not show immediate signs of damage, but over time, breaks down the skin’s collagen and elastic and thereby can accelerate wrinkles, leathery skin and skin cancers.
