Microplastics in Sunscreen The Hidden Threat to Our Oceans

When we think of sunscreen, we usually focus on its ability to protect our skin from harmful UV rays. However, what if the sunscreen we trust to shield us is unknowingly contributing to a much bigger environmental problem? Microplastics—tiny, often invisible particles—are quietly entering our oceans and ecosystems through everyday products, including sunscreen.

This blog post uncovers the hidden truth behind microplastics in sunscreens, their devastating impact on marine life, and how Aiguadolç is leading the way with eco-friendly alternatives that protect both your skin and the environment.

Microplastics are small plastic particles, less than 5mm in diameter, that are often used in personal care products to enhance texture, spreadability, or improve product performance. Sunscreens are one of the most common sources of microplastic pollution, and their presence in these products is alarming.

Many sunscreens contain synthetic materials, commonly used as "smoothing agents," that break down into microplastics in water. Once they enter the ocean, they do not biodegrade. The result? These tiny particles accumulate in marine ecosystems, posing a significant threat to ocean life. 

Studies show that up to 83% of popular suncare products contain microplastics or ingredients that degrade into microplastics when exposed to water. This widespread contamination is a major contributor to the growing problem of marine pollution. Microplastics can persist for decades in the oceans, disrupting marine ecosystems and entering the food chain through ingestion by marine animals.

Once microplastics are released into the ocean, they have a devastating effect on marine life. In addition to chemical pollutants like oxybenzone and octinoxate—which are common in sunscreens and contribute to coral bleaching—microplastics act as a silent invader. Marine animals mistake these particles for food, ingesting them unknowingly.

The consequences are dire:

• Marine animals ingesting microplastics face severe health issues, including reproductive problems, digestive blockages, and sometimes death.
• Coral reefs, which host 25% of marine species, are particularly vulnerable. Sunscreen microplastics contribute to reef degradation, making it even harder for coral ecosystems to thrive.

In fact, it’s estimated that 14,000 tons of sunscreen enter coral-rich waters every year. This is part of the reason why coral reefs around the world are suffering at an alarming rate.

The good news is that we can all take small steps to reduce microplastic pollution by making informed choices about the products we use.
