Why you should choose Natural Sunscreen?
Hello Sunshines,
When looking for sun protection, more people than ever are looking for natural sunscreens without harmful chemicals and irritants. In fact, the natural sun protection products market is projected to bring in nearly $1 billion by 2030. But natural and organic sunscreens still only make up about 5–7% of the total sun care market. So what do you need to know about sunscreen to help you make the best choice for yourself and your family?
Chemical Sunscreens vs. Physical Sunscreens
For many years now, people have been categorizing sunscreens into two groups — chemical and physical. Chemical sunscreens use man-made chemicals to reduce sun damage by absorbing UV rays.
Physical sunscreens, on the other hand, are made with natural elements and are said to block or scatter UV rays so they never penetrate the skin in the first place.
The Problem with Chemical Sunscreens
Studies have shown that a number of the ingredients found in chemical sunscreens may be detrimental to your health and have a negative impact on the environment as well. Let’s look at some of the most commonly found chemicals in sunscreens, and why you might want to think twice before rubbing one into your skin.
Avobenzone
First discovered in the 1970s, avobenzone is one of the most widely used active ingredients in chemical sunscreens. It’s regulated as an organic, broad-spectrum UV filter.
Research has shown that the byproducts of avobenzone can cause allergic reactions and may also have hormone-disrupting effects.
One study examining sunscreen use and blood plasma concentrations showed that the body absorbs avobenzone at amounts nine times beyond the FDA threshold of 0.5 nanograms per milliliter (ng/mL). This threshold was exceeded even after a single day of sunscreen application.
Oxybenzone
Oxybenzone is frequently seen as a chemical of concern by doctors and researchers. It’s readily absorbed through the skin in significant amounts and was found in the blood of 97% of Americans tested. This is concerning because oxybenzone has been linked to allergic reactions, hormone disruption, and cell damage.
One study found that 24% of breast milk sampled contained detectable amounts of ozybenzone. And another recent paper from the Journal of Reproductive Toxicology suggests that pregnant women who use sunscreen containing oxybenzone may put their child at a higher risk of developing a birth defect known as Hirschsprung’s disease.
The American Academy of Pediatrics advises parents to avoid using sunscreens containing oxybenzone on children if at all possible. And although US sunscreen manufacturers are allowed to use it in concentrations up to 6%, the European Commission has recently published preliminary opinions suggesting that oxybenzone is unsafe.
Homosalate
Homosalate is frequently used in sunscreens for its ability to absorb short-wave UVB rays.
It’s been implicated for its endocrine-disrupting effects, raising concerns that it could contribute to breast and other hormonal cancers. Although it’s allowed by the FDA in concentrations up to 15%, homosalate is not currently recognized as a safe sunscreen ingredient. Homosalate is one of 12 sunscreen ingredients currently under review in the US.
The European Union’s Scientific Committee for Consumer Safety also recently released an opinion stating they believe homosalate is not safe in amounts up to 10%.
Octinoxate
Octinoxate is what’s known as a cinnamate, a classification of UVB sunscreens related to cinnamon oil. Cinnamates are absorbed rapidly into the skin and may show up in blood, urine, and breast milk. And both in vitro and in vivo studies have raised suspicions that octinoxate is an endocrine disruptor. Octinoxate has also been linked to allergic reactions in some individuals.
And — as if you needed another reason to watch out for this chemical — in 2021, both Hawaii and the Florida Keys banned sunscreens containing octinoxate due to their toxic effect on marine life.
Octisalate
Octisalate is a chemical derivative of salicylic acid that’s commonly used in sunscreens. In a recent study with five other chemical sunscreen ingredients, octisalate showed an absorption rate 10 times that of the threshold allowed for in the study.
Octocrylene
Another “O” to be wary of in chemical sunscreens is a compound known as octocrylene. It’s used for its ability to absorb UVA and UVB radiation. However, octocrylene is a known photosensitizer which means that when exposed to UV light, it can increase the production of free radicals in neighboring cells. Data has also revealed that this chemical accumulates in marine life and can cause cellular dysfunction in coral.
Although it’s approved by the FDA in concentrations under 10%, researchers petitioned to have octocrylene sunscreens removed from the market in 2021.
Retinyl Palmitate
Retinyl palmitate (also known as retinol palmitate) is a chemical compound made from vitamin A and palmitic acid. According to FDA data and research from the National Toxicology Program, retinyl palmitate may speed the development of skin tumors and lesions when applied to the skin in direct sunlight. And although this finding has been affirmed by the NTP’s Board of Scientific Counselors, the FDA has still not concluded its follow-up studies, which are intended to assess whether this chemical has a carcinogenic effect on humans.
The Benefits of Physical or Natural Sunscreens
The risks associated with chemical sunscreens are numerous, so it’s easy to see why more and more people are interested in natural sunscreen options. Many dermatologists and other skin care experts now recommend using so-called “physical” sunscreens, which are considered safer options because they offer broad-spectrum protection and lack hormone-disrupting risks. Two of the best-known minerals used in natural sunscreens are titanium dioxide and zinc oxide.
Zinc Oxide or Titanium Dioxide Sunscreen?
When formulating natural sun protection, the highest priorities should be broad-spectrum protection and safety. It’s important to offer protection from both UVA and UVB rays, along with protection from free radicals, which cause premature aging.
Zinc oxide has been used as sun protection for a long time. It offers broad-spectrum protection, shielding you from both UVB rays, which cause sunburn, and UVA rays, which penetrate more deeply and may be more dangerous in terms of causing skin cancer.
Though titanium dioxide works in a similar manner in providing broad-spectrum protection, its safety isn’t as well-documented as zinc’s. Zinc is an essential mineral that we actually need in our bodies for optimal function. And zinc is the only active sunscreen ingredient approved by the FDA for infants under six months.
A number of studies have demonstrated the superiority of zinc over other types of sunscreens. Here’s a small sample:
Researchers tested zinc oxide and found it offered broad-spectrum UV protection, and was “photostable,” meaning it didn’t alter in dangerous ways when exposed to UV rays.
In 2000, researchers compared zinc oxide with titanium dioxide for their abilities to weaken UVA radiation. They found that zinc oxide provided superior protection against long-wave, damaging UVA rays.
Concerns with Spray-On Sunscreens
Spray-on sunscreens have become very popular in modern cosmetics — and the appeal is understandable. The quick and easy application is favored for hard-to-reach areas or wriggling, resistant children. But the truth is that these aerosolized sunblocks may pose more risk than convenience.
Too thin a layer of sunscreen is a primary reason that chemical or physical sunscreens may not be particularly effective — and this is an especially pronounced problem for spray-on sunscreens. Researchers from Australia concluded that even a light breeze is enough to significantly reduce the effective coverage of sunscreen sprays — so much so that an entire bottle may not be enough to provide adequate protection.
Another concern with spray-on sunscreens is inhalation. The ultrafine particles of aerosol sprays can travel deep into the lungs and may have the potential to cause serious damage. Many sunscreen sprays have now been discovered to be contaminated with benzene — a cancer-causing compound that federal regulators don’t require testing for!
What About SPF?
Many of us have come to consider the SPF, or “sun protection factor,” carefully when choosing a sunscreen. The higher the number, the more protection, right? The thing is, SPF only refers to protection from UVB rays. Because they’re responsible for sunburn, we might think that’s the only protection we need.
Yet, UVA rays are considered even more dangerous, as they penetrate the skin more deeply and are linked to skin cancer. But SPF does not measure a sunscreen’s protection against UVA rays — only UVB rays.
To further explain — the SPF is a measurement of the difference between the amount of sunlight that causes redness in sunscreen-protected skin, and the amount that causes redness in unprotected skin. A sunscreen with an SPF of 15 theoretically gives you 15 times the minutes to stay out before you burn.
For example, if you usually burn in 10 minutes and you apply an SPF 15 product, you can stay out for 150 minutes. There are some problems with this equation, though. It makes people believe that an SPF 30 would allow them to remain twice as long in the sun as an SPF 15. In truth, an SPF 15 blocks about 93% of UVB rays, while an SPF 30 blocks about 97%, and an SPF 50 about 98%. So going higher and higher doesn’t necessarily create more protection after a certain point.
In addition, these numbers have nothing to do with UVA rays, so people who slather on an SPF 50 and stay in the sun for hours are likely to suffer even more severe skin damage if they don’t have a “broad spectrum” sunscreen that protects from both UVA and UVB rays.
Studies just don’t support the idea that, past a certain point, a higher SPF provides more protection. In addition, high SPF products are often made with greater percentages of chemical ingredients, which may be linked to hormone disruption, trigger allergic reactions, and potentially expose you to more free-radical damage.
Bottom Line — Your skin needs Protection & Moisturizing.
There’s no doubt that UV exposure increases the risk for skin cancer and accelerates the appearance of aging. A healthy skin care regimen should include protection. We believe we’ve found the best of all worlds with this all-natural formula:
Zinc oxide is still considered the safest option for sunscreens. It’s the only sunscreen recommended by the FDA for babies. It offers superior broad-spectrum protection against both UVA and UVB rays and helps decrease the risk of skin cancer and early skin aging caused by the sun.
Antioxidants neutralize environmental stressors. Part of the reason UV rays damage skin is that they create damaging stressors. Using ingredients like vitamin E and olive oil that are chock-full of antioxidants protects the skin against environmental stressors. And, to boot, they will give the look of clarified, brighter skin.
Natural protection: When you apply sunscreen, you have a golden opportunity to add some nourishment as well as protection to your skin. Red Raspberry Seed oil is the top-ranked natural protection among the oils: spf 35-45! A gourmet ingredient in natural formulas that not only highly add to the mineral protection but helps reduce the appearance of fine lines and wrinkles. Avocado oil has been shown in studies to have a natural spf of 5-15.
Natural soothers help calm skin when it’s overexposed, allowing it to stay comfortable. This includes ingredients that have a natural ability to soothe, like mango butter, nourishing and visibly enhancing your skin’s glow. Coconut oil may help reduce pain, swelling, and redness while helping to restore moisture to the sunburn area. Carrot oil can be used topically to heal and soothe dry skin and promote quick healing and maximize the absorption of Vitamin D.
Natural moisturizers keep skin hydrated and healthy. The stronger and more cohesive your skin is, the better it’s able to resist UV damage. Hydration is a key part of this process, as dry skin is likely to crack and flake, making skin more vulnerable to UV damage and premature aging.
