The basics of sun protection
Spending time in the sun increases your risk of skin cancer and early skin aging. To decrease the risk of sunburns and sun damage, regularly use a broad spectrum (protecting against both UVA and UVB rays) sunscreen rated SPF 50+ and other sun protection measures including:
- limit time in the sun, especially from 10 a.m. – 4 p.m.
- wear UPF 50+ rated clothing including wide-brim hats, long-sleeved shirts, dresses, and pants
- seek shade from buildings and trees, or make use of a sun parasol
UVA rays cause tanning while UVB rays are responsible for causing sunburns. It is a common misconception that only sunburns are reason for concern, when the tanning caused by UVA rays is also a visible sign of sun damage and increases the risk for skin cancer.
Sun Protection Factor (SPF) is a measure of how much time a person can be exposed to the sun before getting burned. For example, if you burn in 10 minutes without sunscreen and you apply a liberal dose of sunscreen with a SPF number of 50, you would be protected from a sunburn for 500 minutes.
Mineral Sunscreens vs Chemical Sunscreens
There are two major types of sunscreens: mineral based and chemical based. Mineral based sunscreens function by using zinc oxide and titanium oxide to create a physical barrier that reflects UV rays away from the skin’s surface. Chemical based sunscreens function by making use of chemical UV filters that absorb UV radiation.
There is some controversy around chemical UV filters as studies have shown they are absorbed into the bloodstream and cause hormone disruption and even cancer. Chemical based UV filters have also been proven by researchers to cause damage coral DNA and larvae, contribute to coral bleaching, and affect the health of algae, fish, shellfish, urchins, and marine mammals.
Ingredients to avoid
According to the Haereticus Lab, the following sunscreen ingredients have all been found to cause damage to coral reefs. Unfortunately, many sunscreens that contain these harmful chemicals are still labelled as reef safe since there is no certification or testing requirement for this claim, so it’s important to always check ingredients when shopping.
- 4-Methylbenzylidene Camphor [4-MBC]
- Para-Aminobenzoic Acid [PABA]
- Any nanoparticles or “nano-sized” zinc or titanium
- Any form of microplastic, such as “exfoliating beads”
A single drop of oxybenzone in 4.3 million gallons of water—six and a half Olympic sized swimming pools—is enough to be deadly. It’s estimated that around 14,000 tons of sunscreen end up in the world’s coral reefs annually, causing irreparable damage to the ecosystem.
Ingredients to look for
Mineral sunscreens formulated with non-nano zinc oxide and titanium oxide are the only sunscreens considered to be safe, effective, and eco-friendly. We recommend covering up as much of your skin as possible with UPF 50+ clothing and applying a broad spectrum mineral sunscreen to exposed areas of skin as needed.
The harmful ingredients found in chemical sunscreens and other personal care products are washed off in the shower and flow through local water streams into the ocean, so it’s important to use a eco-friendly mineral sunscreen no matter how far you are from the ocean.
