Sunscreen Guide
During summer months especially, many people are more thoughtful about sun protection. The conversation and research on sunscreen -- what the safest sunscreens are to use, and what are the environmental impacts of sunscreen are – is becoming more widespread. This is the sunscreen brush I use to apply the sunscreen. Ideally I always use natural bristles, this is when I apply my 80/20 rule as the bristles in this brush are plastic in order to hold up when applying sunscreen. If you are concerned, using your hands to spread it is best.

Titanium Dioxide – “Regular supply of TiO2 NPs at small doses can affect the intestinal mucosa, the brain, the heart and other intestinal organs, which can lead to an increased risk of developing many diseases, tumours or progress of existing cancer progresses. The mechanism behind the nanotoxicity of NPs has not been discovered yet. Many studies attribute to oxidative stress, thus nanotoxicity is still an important area for future exploration”.

Polyaminopropyl Biguanide (less than 0.1% per EU restrictions) - The Expert Panel for Cosmetic Ingredient Safety reviewed the safety of Polyaminopropyl Biguanide, which is a preservative in cosmetic products, and concluded that the data is insufficient to determine the safety in products that may be accidentally inhaled. Otherwise, it is safe at a low concentration and when formulated to be nonirritating and non-sensitizing.

I prefer mineral sunscreens, which sit on top of the skin to protect and filter out UV rays (versus chemical sunscreens which absorb into the skin). Mineral sunscreens typically include titanium dioxide or zinc oxide and are broad-spectrum, providing protection from both UVA and UVB rays. Because mineral sunscreens work by creating a protective barrier between the skin and UV rays, it works pretty much immediately upon application, but can also leave a white film on the skin. I always look for sunscreen with an SPF of at least 30. And I am always careful to avoid ingredients such as added fragrances, chemicals, and dyes. Of note, AAP recommends keeping babies under 6 months old out of the sun with loose-fitting clothes that cover all of the skin). See notes on what sunscreens were found to be safe for babies 6 months of age and older.
Over-the-counter sunscreens are regulated by the FDA under the Sunscreen Innovation Act. In the recent FDA proposed rule, 2 active ingredients (zinc oxide and titanium dioxide) were found to be generally recognized as safe and effective (GRASE), while 12 active ingredients (cinoxate, dioxybenzone, ensulizole, homosalate, meradimate, octinoxate, octisalate, octocrylene, padimate O, sulisobenzone, oxybenzone, and avobenzone) had insufficient data and therefore, more data has been requested from the sunscreen manufacturers.
Studies have shown that sunscreen chemicals can be absorbed systemically and sometimes even at levels above the FDA-established threshold. Another study, found that the blood concentration of some of these sunscreen chemicals continued to rise as daily use continued.
From an environmental perspective, studies also indicated that sunscreens play a role in damaging our coral reefs. Recently, Hawaii as well as the only living coral reef in North America: Key West, Florida, have banned sunscreens containing oxybenzone and octinoxate because they cause coral bleaching and are dangerous to marine ecosystems.
To keep our oceans healthy, the key is to find a sunscreen with the active ingredients: zinc oxide and titanium dioxide as they provide a physical block to protect the skin from absorbing any rays (whereas chemical sunscreen absorbs UV rays, turns the rays into heat, then releases them from the skin). There is also still further research being done about the concern about nanoparticles in sunscreen, particularly zinc oxide and titanium dioxide. When purchasing sunscreen, you can also make sure your sunscreen doesn’t include any harmful ingredients listed on the HEL list.
