Back then, sunscreen served only as prevention from sunburn. Soon, people found that it was important to protect themselves from the sunís UV-rays as well, infusing ingredients that act like a barrier towards these harmful rays. Fast-forward to present time, researchers have found that sunscreen can have negative effects as well, taking measures to ensure sunscreens protect the skin while avoiding these negative effects. This is where biodegradable sunscreen comes into the picture. Indeed, there are differences between biodegradable and non-biodegradable sunscreen which you should be aware of.

A bottle of non-biodegradable sunscreen basically consists of ingredients that do not biodegrade. This means that the chemicals simply stay intact, which can harm the environment for years or even decades before the substance actually decomposes. Unfortunately, the decomposition process can also be quite a bother as it forms a reaction within the chemicals involved, which would become a corrosive pollutant. The ingredients that are often used in the chemicals of non-biodegradable sunscreen are like parabens, cinnamates, and benzophenones, which are very detrimental ingredients to both the environment and humans. Likewise, it can affect the environment which consequently affects humans as well.

Biodegradable sunscreen, on the other hand, is made out of ingredients that biodegrades. It is made out of mineral ingredients that allow the biodegrading process to take place, like zinc oxide, titanium oxide, or other similar minerals. Of course, one cannot apply the mineral alone on the skin, so instead of mixing them with harmful ingredients, they are mixed with natural ingredients like organic butters, and plant oils, or even synthetically derived natural ingredients like shea butter. Ingredients like shea butter are not exactly all natural, but it is much cheaper to produce and sold at high prices. What happens with the combination of the minerals and the organic ingredients is that when worn for a play or swim in the ocean, they can get washed off into the ocean. However, they do not affect the surroundings; instead, they collect on the sea floor like silt, which eventually gets buried within the sand. These mineral ingredients have low toxicity levels so if a human or an organic life form happens to ingest them; they do not affect the system and is easily excreted from the system. Interestingly, this fact is often used as a marketing tactic to sell biodegradable sunscreen because they are somewhat safe to eat, although one really should not actually be doing so.
