What's In Your Sunscreen? The Debate Over Oxybenzone, Avobenzone & Chemical Sun Protection

The chemical additive known as oxybenzone, used as a product stabilizer and UV protectant in many sunscreen and skin care products, may be gradually bleaching and killing the world’s coral reefs.
Which may leave you wondering: What's in your sunscreen?


How to Read a Sunscreen Label

Not all sunscreens are created equal, which of course is why there are so many to choose from--something you may be familiar with after spending any amount of time near a sunscreen aisle or online attempting to make the best decision for your skin. The front of every tube seems to have its own defining factors, but what you really should be looking at is the ingredient panel. It may seem intimidating at first glance, but it’s totally worth knowing what’s in your sunscreen products.

Many sunscreens feature active ingredients oxybenzone, avobenzone, octisalate, octocrylene, and octinoxate—or some combination of those chemicals. What are active ingredients? Good question. The active ingredients are the ingredients in a product that are biologically active. Essentially, these are the ingredients doing most of the work. In the case of sunscreen, the active ingredients are those that actually keep you safe from the sun. However, not all active ingredients are created equal either. Some of the chemical ingredients, most notably oxybenzone, have been shown to damage the ecosystem. We suggest you should look for mineral active ingredients—like zinc oxide, titanium dioxide, or both—in the ingredient panel.


Concerns About Oxybenzone

The purpose of oxybenzone in sunscreen is to absorb the UV radiation produced by the sun before it has the opportunity to damage your skin. It can slow the effects of sun exposure, like dark spot formation, and minimizes the risk of sunburn. Sounds good, if not for the disturbing scientific discoveries that were made public in 2015.  Results of extensive environmental research published in the Archives of Environmental Contamination and Toxicology revealed that oxybenzone in the ocean is a major contributor to widespread coral bleaching. This chemical is wreaking havoc on the undersea environment and accelerating damage that was already resulting in coral destruction. As little as a teaspoon of oxybenzone-containing sunscreen can cause coral bleaching. This is just a fraction of the amount of sunscreen needed to cover the body before sun exposure—not to mention reapplying.

Aside from the environmental repercussions, some scientific evidence would indicate that oxybenzone stays in the body, and may lead to hormone disruption (Janjua 2004; Environmental Working Group, 2008).


How to Choose a Sunscreen? - 3 Sunscreen Buying Tips

After all of this talk of chemicals, there are still good options out there. Just keep these few things in mind:

  1. Stick to sunscreens with mineral active ingredients (usually zinc oxide or titanium dioxide, if not both)
  2. Make sure the formula provides broad-spectrum protection. Broad-spectrum sunscreens protect against both UVA and UVB rays, both of which are damaging in their own way
  3. Choose mineral. Keep the environment in mind by choosing a sunscreen that is reef friendly and biodegradable.
