There’s concern whether nanoparticles are safe to use in sunblocks, and the limited research that exists has provided mixed results. Also, the mining of zinc and ilmenite to produce titanium dioxide aren’t without their local environmental impacts. Thus, it helps to find ones that match your skin color most come in different colored tints. They tend not to rub in as clearly and have lower rated SPFs. While sunscreens that use minerals like zinc oxide or titanium dioxide to reflect sunrays seem to be less likely to negatively impact marine life and humans, they have some disadvantages. Note that some brands have “reef-safe” on their label, however these indications are unregulated, so best to look at the ingredient list. Granted, any effect on reefs will be dwarfed in comparison to the impact of climate change, so if reefs are a motivating factor for you, know that everyone avoiding chemicals in their sunblock isn’t going to save the reefs. While these chemical concentrations are low this doesn’t mean they can’t or will not eventually have an active effect on delicate marine life. Believe it or not, given the popularity of these hot tourist destinations a lot of sunblock washes off into the ocean, and not to mention the effect of waste water runoff. The issue is that some research on these chemicals have been linked to damage to not only humans but also coral reefs. Most major brands use chemical blockers in order to provide higher SPFs and for better waterproofing. (watch out for chemistry sounding ingredients like polymers) by Jason Denney Also, be sure to read the label carefully and avoid the sunscreen ingredients listed above.Avoid chemicals & microplastics. When shopping for sunscreen, you can look for ROOPAYUR SUNSCREEN MOISTURIZER instead of chemical sunscreens. In conclusion, it's important to choose sunscreens that are free of harmful ingredients, not just for the health of our skin, but also for the health of the environment. The EWG recommends avoiding sunscreens with nano zinc oxide. However, nano zinc oxide particles are so small that they can be absorbed into the bloodstream and may have negative health effects. Zinc oxide is a mineral sunscreen ingredient that reflects UV rays. PABA has been largely replaced by other sunscreen ingredients, but it may still be found in some products. However, it has been linked to skin irritation, allergic reactions, and can stain clothing. PABA is a chemical sunscreen ingredient that absorbs UVB rays. The EWG rates octocrylene as a moderate hazard ingredient. However, it can produce free radicals when exposed to sunlight and has been linked to skin irritation. Octocrylene is a chemical sunscreen ingredient that helps stabilize other sunscreen ingredients. The EWG rates homosalate as a moderate hazard ingredient. It has been found to disrupt hormones and can also accumulate in the body over time. Homosalate is a chemical sunscreen ingredient that absorbs UV rays. The EWG recommends avoiding sunscreens with retinyl palmitate. However, when exposed to sunlight, retinyl palmitate can break down and produce free radicals that can damage skin cells. Retinyl palmitate is a form of vitamin A that is commonly added to sunscreen for its anti-aging properties. Octinoxate has been banned or restricted in several places around the world, including Hawaii and the European Union. It has also been linked to hormone disruption and can be harmful to coral reefs. Octinoxate is another chemical sunscreen ingredient that absorbs UV rays. According to the Environmental Working Group (EWG), oxybenzone is a high hazard ingredient and should be avoided. However, it has been linked to hormone disruption, allergic reactions, and it can be harmful to coral reefs. Oxybenzone is a common chemical sunscreen ingredient that absorbs UV rays. In this blog post, we'll explore some of the sunscreen ingredients to avoid and why. Some sunscreen ingredients can be harmful to both our skin and the environment. Sunscreen is an important tool to protect our skin from the harmful effects of the sun, but not all sunscreens are created equal.
