S4 Sport’s world-class protection is credited to two factors: 1) its PURE PHYSICAL nature and, 2) its inherent PHOTOSTABILITY.

PURE PHYSICAL means that the only active ingredients used in S4 Sport are Zinc Oxide or Titanium Dioxide, or a combination of both. These are natural minerals, hence the “PURE” for natural and “PHYSICAL” for minerals.
To protect the skin, chemical sunscreens use UV filters that absorb radiation from the sun. When a sunscreen is exposed to this radiation, it can alter the chemical structure of the UV filters, thus degrading its ability to maintain itself and forfeiting skin protection. A "PHOTOSTABLE" sunscreen maintains its ability to protect against the sun's harmful rays — even in the presence of UV radiation.
S4 Sport is PHOTOSTABLE. We do not use chemical UV filters or absorbers. S4 sunscreens only use Zinc and Titanium as active ingredients. These metals are natural sun-blocks that DO NOT breakdown in the presence of UV radiation.
S4 formulates with only the best ingredients.
Still not convinced? Here are some other FAQ’s:
A. S4 stands for Sun, Surf, Sand and Snow. S4 Suncare is for all your outdoor endeavors.
A. Broad spectrum protects against the harmful effects of both UVA (long wavelengths- aging rays) and UVB (shorter wavelengths - burning rays) UVA can penetrate through windows and penetrates deeper into the dermis. Generally thought to be responsible for wrinkles, premature aging, cellular level and long term damage. UVB rays are responsible for damage to the outer layers of the skin and are the main cause of sunburn. They also play a role in skin cancer.
A. The SPF (Sun Protection Factor) measures the UVB – that is the burning rays/ shorter rays. UVB affects the outer layer of skin, the epidermis, and is responsible for your tan lines and sunburns. It is most intense between 10:00 and 2:00 when the sun is brightest and closest to Earth. UVB does not penetrate glass.
While nothing blocks the sun 100%, the higher the SPF level is, the better it will deflect harmful UVB rays. What SPF value you choose should be based upon your skin type and degree of sun exposure.
SPF 15- 93.0%
SPF 20- 95.5%
SPF 25- 96.0%
SPF 30- 97.0%
SPF 50- 98.0%
Everyone has a different skin type based on the amounts of melanin (pigment) in the skin. The Fitzpatrick Phototype Scale (standardized scale used by dermatologists and other medical professionals). The lighter or fairer your skin type, the more susceptible you are to sunburn and sun-induced skin damage. Knowing your skin type is important in determining your safe period and SPF you should be using.
TYPE I-Ivory White, no tanning ability, always burns
TYPE II- White, minimal to weak tanning ability, high inclination to sunburn.
TYPE III- White, Low tanning ability, moderate inclination to sunburn.
TYPE IV- Beige-Olive, lightly tanned, moderate tanning ability, very low inclination to sunburn
TYPE V- Moderate brown or tanned, sun insensitive skin, very low inclination to sunburn.
TYPE VI- Dark brown or black, sun insensitive skin, never burns.
The FDA, CDC and Skin Cancer Foundation recommend choosing a sunscreen based on your specific needs. You should not be using a higher SPF sunscreen that you need to, because the concentration of chemicals relative to the protection they afford is much higher in products with higher SPF ratings. *****Note, S4 sunscreens do not use chemical filters in their SPF protection. S4 sunscreens are formulated with only physical (mineral or natural) sun protectants. *****
A. Reef Safe and biodegradable claims on sunscreens are unregulated and have been controversial. There have been claims that chemical sunscreens have been partially responsible for bleaching coral reefs. These claims are difficult to conclusively prove, but no one wants to contribute to bleaching our coral reefs.
Mineral (physical) sunscreens (Zinc Oxide or Titanium Dioxide) often claim "Reef Safe" because they are of the earth, they belong there. They do not biodegrade and will settle into the sediment of the ocean floor making it unlikely that it will come in contact with the reef or other aquatic life in the future.
If you are swimming, snorkeling or diving near a coral reef, use S4 Sport (a pure physical) sunscreen with 80 minutes water resistance and it is unlikely that your sunscreen will introduce any problems to the marine life.
A. An unstable (uneven number of electrons) looking to stabilize itself by stealing an electron from a healthy (evenly paired electron) cell. Once an electron is stolen, cellular death occurs. This happens a gazillion times a day. Free radicals come from our environment (sun, pollution, smoke) and are thought to contribute to cancer, aging and other diseases.
A. They are the Kryptonite to Free Radicals. They are molecules that can safely interact with Free Radicals and terminate the chain reaction before cellular damage occurs. (Antioxidants, have extra stable electron to donate to a Free Radical in order to stabilize it and stop further damage from occurring). We get Antioxidants from fruits, vegetables and other healthy foods we eat. We also get them from some skin care and nutritional supplements. All S4 products include Antioxidants in their formulas to give an added level of protection.
A. To protect the skin, chemical sunscreens use UV filters that absorb radiation from the sun. When a sunscreen is exposed to this radiation, it can alter the chemical structure of the UV filters, thus degrading its ability to maintain itself and forfeiting skin protection. A "photostable" sunscreen maintains its ability to protect from the sun's harmful rays even in the presence of UV radiation.
S4 sunscreens are Photostable. S4 does not use chemical UV filters. S4 only uses Zinc and Titanium as active ingredients. They are natural sunscreens from the earth that do NOT breakdown in the presence of UV radiation.
A. S4 uses only Pure Physical actives. This means the active ingredients are only Zinc Oxide or Titanium Dioxide or a combination of both. S4 does not use Chemical UV filters or absorbers. S4 formulates with only the best ingredients for your protection.
A. S4 Suncare prices are comparable to other premium natural suncare products. S4 uses only the best natural actives in their products and our products comply with the strictest of guidelines and quality control standards. Natural sunscreens are often able to offer a more consistent and dependable suncare protection than its chemical competitors.
A. S4 does not and will not test on animals.
