The Truth About Mainstream Sunscreen

Updated: Sep 19

Everywhere we go there are toxins. During the summertime there are many toxins we may not realize are in our reach. Bug repellants. Sunless tanners. Sunscreen. After-sun products. The list goes on. Not only are these toxic to humans, but also to the environment and aquatic life.

Certain ingredients found in sunscreens have been banned in many locations including the U.S. Virgin Islands, Hawaii, Key West, Florida, Bonaire, Palau, and multiple Mexican vacation spots (1). Certain ingredients can induce bleaching and damage DNA, deform or even kill coral. This is such a problem that the Center for Biological Diversity has petitioned the Federal Drug Administration (FDA) to nationally ban these coral-killing sunscreen ingredients (2).

The 7 Best Sunscreens on the Market

Did you see New York Post's article 7 Best Sunscreens to Protect the Whole Family, Per Experts published in 2022? This article featured sunscreen recommendations with chemical ingredients such as avobenzone and oxybenzone, which they claim work by absorbing UV rays and reducing their penetration into the skin. These are the same ingredients that have been banned in several locations. Aside from those chemicals, do you know what else is in these "best" sunscreens? What about the dangers associated with those ingredients? We are going to take a closer look into each of these specific sunscreens and their ingredients. Then we will take an even closer look at why these ingredients are toxic to us.

The Toxic Impacts of Sunscreen

While swimmers and snorkelers standing on or touching the fragile ecosystems present their own threat, an even more pressing danger has emerged: toxic sunscreens chemicals from mainstream sunscreens. Mainstream sunscreens bleach the coral reefs, preventing them from reforming coral reefs and interfering with reproduction in fish and turtles while harming the entire ocean (3). For good reason, the most commonly banned sunscreen ingredients are octocrylene, avobenzone, octinoxate, and oxybenzone. Studies have found that these four petrochemical sunscreens are toxic to human health, coral reefs, and marine species.

  • Octocrylene, although claimed to be a "pure" ingredient, is often contaminated with benzophenone, a mutagen, carcinogen, and endocrine disruptor (4). Benzophenone is a class of benzophenones, a formaldehyde in which both hydrogens are replaced by phenyl groups (5). short-term exposure to formaldehyde has been linked to coughing, headaches, dizziness, nausea, eye, nose, and throat irritation, while long-term exposure to formaldehyde may cause certain types of cancer (6). Additionally, Benzophenone accumulates over time from the degradation of octocrylene in mainstream sunscreen products. A study examined six different study sites in Brazil for the presence of octocrylene in the livers of Franciscana dolphins. The dolphins were either stranded or accidentally caught in fishing nets along the Brazilian coast between 1994 and 2009. The study found high concentrations of octocrylene in 21 out of the 56 dolphin livers analyzed (7).

  • Avobenzone is an oil-soluble, light-sensitive ingredient derived from dibenzoylmethane (8). Oceanographers have found this petrochemical to damage marine and reef environments, increasing the rate of coral bleaching (9). According to Dibenzoylmethane Safety Data Sheet, upon skin contact with this chemical, you should "wash off immediately with soap and plenty of water while removing all contaminated clothes and shoes. Get medical attention (10)." Aside from that, Avobenzone degrades when sun exposure, resulting in harmful free radicals being released into the body (11). Avobenzone can disrupt the endocrine system and can be found in the blood weeks after use (12).

  • Octinoxate or Octyl methoxycinnamate (OMC) is often marketed as "natural" despite being a mix of sulfuric acid and methanol, a petroleum by-product (13). This chemical is dangerous to beaches, aquatic life, and coral reefs. This ingredient can also be found in some drinking water supplies (14). This ingredient is absorbed into the body quickly and has been detected in human urine, blood, and breast milk even after use (15). Octinoxate is an endocrine disruptor, mimicking estrogen, and can disrupt thyroid function (16).

  • Oxybenzone, known as benzophenone-3 amongst other names, is a chemical compound that blocks UV rays (17). This chemical releases toxins in the corals' water, stressing their symbiotic partners. Stress awakens dormant viral infections in algae, causing the coral to expel the algae, which may lead to death (18). Oxybenzone also affects humans and is considered a hazardous eye irritant and allergen (19). Additionally, this ingredient can interfere with hormones and has been found in human breast milk, amniotic fluid, urine, and blood. Finally, children may be more vulnerable to the health hazards associated with oxybenzone (20).

Octocrylene, avobenzone, octinoxate, and oxybenzone aren’t the only toxic ingredients that can wreak havoc in the oceans. According to the National Ocean Service (NOAA), sunscreens' ingredients can cause marine life problems: benzophenones, OD-PABA, 4-methylbenzylidene camphor, 3-benzylidene camphor, nano-titanium dioxide, and nano-zinc oxide.


The issue affects more than our beautiful coral reef systems, the NOAA, details the following impacts on marine life exposed to toxic sunscreen ingredients (21):

  • Green Algae: Can impair growth and photosynthesis.

  • Coral: Accumulates in tissues. It can induce bleaching, damage DNA, deform young, and even kill.

  • Mussels: Can induce defects in young.

  • Sea Urchins: Can damage immune and reproductive systems and deform young.

  • Fish: Can decrease fertility and reproduction and cause female characteristics in male fish.

  • Dolphins: Can accumulate in the tissue and be transferred to young.

Aside from the many dangers of the ingredients that make sunscreen, sunscreen, there are many additives that cause additional toxicity to the body. To name a few:

  • Petroleum clogs pores and often causes acne breakouts as well as rashes. Petroleum has also been linked to estrogen dominance. Estrogen dominance is a common condition in which sufferers have a high ratio of estrogen, with little to no progesterone to balance its effects in the body (22).

  • Caprylyl Glycol is an alcohol derived from a fatty acid. It is a humectant that pulls water into the skin and helps to hold moisture into the skin. The problem is that it can irritate some skin types, particularly those already sensitized or irritated (23).

  • Dimethicone is silicone-based which you do not want. Why don’t you want a silicone-based product? Silicone-based products will form a barrier on top of your skin that can trap dirt, sweat, bacteria, sebum, dead skin cells, and other debris, and it can dehydrate your skin and interfere with cell renewal, among other things (24).

  • Stearic Acid may cause a few side effects, including eye irritation, skin irritation, gastrointestinal irritation like nausea, vomiting, and diarrhea, respiratory tract irritation (25).

Natural Sun-Protection Recommendations

Remember, exposure to sun rays is not always considered bad. In fact, exposure to these rays has shown to be particularly helpful in treating vitamin D deficiency, seasonal affective disorders, psoriasis, sarcoidosis, mycosis fungoides, and numerous other cutaneous conditions (26). For optimal sun exposure, get around ten to forty minutes between 10 AM and 3 PM. It’s best to start slowly, around ten minutes, and work your way up to forty. Go in if you notice your skin starting to turn pink. Additionally, you can use some of these natural sun-protection recommendations:

  • Badger's Natural Mineral Sunscreen sets the standard for simple safe sunscreens that protect you and your family. With nourishing and protecting properties and organic ingredients, this brand's mineral sunscreens are ideal for long days in the sun. With a wide variety of options for babies, kids, and adults, this reef and human-friendly option are sure to have something for everyone.

  • Earthley's Sun Shield is a sun protectant lotion that provides a completely natural way of safeguarding your skin from sun damage. This lotion doesn’t absorb the sun’s rays or reflect them. Instead, it penetrates deeply into the skin to help prevent damage at the cellular level. Raspberry seed oil protects against UVA and UVB rays, while the oils and butters naturally have SPF ranging from 2 up to 50 SPF each. Sun Shield is NOT an official sunscreen. Depending on your skin type, you may prefer to pair this with a mineral-based sunscreen for particularly hot or sunny days, or you may find it to be enough protection on its own.

  • Two Peas Organics' All-Natural, Organic Mineral Sunscreen uses highly effective plant-derived and certified organic ingredients to provide superior sun protection that is biodegradable and coral reef safe. This sunscreen provides reliable SPF 30 broad spectrum UVA & UVB protection. Gentle enough for a baby's sensitive skin yet strong enough coverage for kids and adults.
