What is The difference between UVA and UVB? (The eco-friendly sunscreens on my list of eco-friendly sunscreens are all broad-spectrum.) If sunscreen isn’t broad-spectrum, it won’t protect you from UVA rays. When5sunscreen is broad-spectrum, it means it protects you from both UVA and UVB rays. None of the 14 UV chemicals is banned in Europe, even coral-reef-bleaching Oxybenzene, despite some American states banning all of them. The FDA found that UV chemicals could be detected in the blood weeks after application and removed 14 out of 16 substances from its GRASE list (generally recognised as safe and effective) until more research can prove they are definitely safe. Some brands advertised as “natural” contain octocrylene. The EU has concluded that it is safe in small amounts and has not banned it. In 2021, new research has been published revealing octocrylene breaks down into a carcinogenic, hormone-disrupting substance called Benzophenone. There is also a higher chance of having an allergic reaction to the active ingredients themselves or the other added chemicals included in mainstream brands, like preservatives and fragrances. There is also some concern over the lack of research on humans, particularly in relation to hormones. Many UV filters are harmful to fish and corals. Here are a few of the downsides to chemical sunscreen:īecause chemical sun cream sinks into your skin, it is much more likely to clog pores and cause acne.Īs sunscreen gets washed off in the shower or the sea, it has been found in large quantities in ocean ecosystems. They are popular because they are less likely to leave a residue on your skin, however, there are lots of concerns about these substances. Most sunscreens you buy in supermarkets and pharmacies are known as “chemical sunscreens.” They contain UV filters that absorb into your skin and block UV rays. What are the problems with chemical sunscreen? If a mineral sunscreen packaging says it is an organic product, it means the other ingredients in the products are grown organically (without toxic pesticides).ģ. The minerals titanium and zinc oxide are not carbon-based so they are inorganic. In this instance, “organic” means a substance with carbon-hydrogen bonds. If you’re used to shopping for food or products with organically-grown ingredients, you might find it confusing that chemical filters are organic but minerals are not. This is particularly problematic for people of colour so I’ve included a nano option on my list to include everyone. The only downside is the bigger particles are more likely to leave a white cast on your skin. However, research has shown that tiny mineral particles, known as nanoparticles, make sea creatures more likely to be harmed by other contaminants.įor this reason, most eco-friendly brands use “non-nano” mineral filters in their products, but it’s always worth checking. Mineral filters, in particular zinc oxide, are considered the most eco-friendly and non-toxic because they don’t bleach coral reefs. Chemical sunscreens contain organic filters that sink into your skin to absorb UV light. Mineral sunscreens are made from zinc or titanium oxide and sit on top of your skin as a shield. There are two types of sunscreens, chemical and mineral. mineral and chemical sunscreen - what is the difference?
