Coola sunscreen is generally safe to use and meets FDA requirements for over-the-counter sun protection. However, safety varies across the product line because Coola sells both mineral and chemical formulas, and these use very different active ingredients with different safety profiles. Understanding which type you’re buying matters more than the brand name on the bottle.
Mineral vs. Chemical: Two Different Formulas
Coola’s product line splits into two camps. Their mineral sunscreens use zinc oxide and titanium dioxide as active ingredients. These are the only two sunscreen filters the FDA currently considers Generally Recognized as Safe and Effective (GRASE). They sit on top of the skin and physically block UV rays rather than being absorbed into the body. Coola’s Mineral Body Sunscreen Lotion SPF 50, for example, contains 3.5% titanium dioxide and 7.25% zinc oxide.
Their chemical sunscreens use a different set of ingredients entirely. The Classic Body Sunscreen SPF 50, for instance, contains avobenzone (1.75%), homosalate (5.0%), octisalate (2.0%), and octocrylene (5.0%). These filters absorb into the skin and neutralize UV radiation through a chemical reaction. The FDA has not classified any of these four ingredients as unsafe, but it has said it needs more data before it can confirm they are safe and effective. That’s a meaningful distinction: it doesn’t mean they’re dangerous, but it means the scientific review isn’t finished.
What the FDA’s Review Actually Means
In its proposed sunscreen rulemaking, the FDA sorted all sunscreen active ingredients into three groups. Zinc oxide and titanium dioxide passed the safety review. Two older ingredients (PABA and trolamine salicylate) failed it. Everything else, including avobenzone, homosalate, octisalate, and octocrylene, landed in a middle category where the FDA wants manufacturers to provide additional absorption and safety data before making a final call.
The concern driving that request is bloodstream absorption. Studies have shown that chemical UV filters can be detected in the blood after normal application, sometimes at levels that exceed the FDA’s threshold for requiring further toxicology testing. That doesn’t prove harm, but it triggered the request for more data. If you want to avoid that uncertainty altogether, Coola’s mineral formulas sidestep the issue.
EWG Safety Ratings for Coola Products
The Environmental Working Group’s Skin Deep database rates most Coola products as either low or moderate hazard. Products that scored low hazard include the Classic Sunscreen Stick SPF 30 and several Liplux lip balms. Products that received moderate hazard ratings include the Classic Body Sunscreen Spray SPF 50 (Guava Mango), the Firming Body Oil Mist SPF 30, and, perhaps surprisingly, the Mineral Body Sunscreen Lotion SPF 50.
That last one is worth noting. A moderate rating on a mineral sunscreen usually reflects concerns about inactive ingredients like fragrances, preservatives, or other additives rather than the sun-blocking agents themselves. The EWG also flags that data availability for many Coola products is “limited,” meaning fewer studies exist on the full formula. This is common for premium sunscreen brands that reformulate frequently.
Fragrance and Sensitive Skin
Many Coola products contain added fragrance, which is a common irritant for people with sensitive or reactive skin. If you’re prone to contact dermatitis or breakouts from sunscreen, look specifically for their fragrance-free options. Coola does offer fragrance-free versions in both their mineral and chemical lines, and these are the better choice for anyone with skin sensitivities, children, or anyone applying sunscreen to their face daily.
Fragrance in sunscreen doesn’t pose a systemic health risk for most people, but it’s one of the top causes of allergic skin reactions in cosmetic products. If you’ve had trouble with sunscreens irritating your skin in the past, this is often the culprit rather than the UV filters themselves.
Reef Safety
Coola’s chemical sunscreens do not appear to contain oxybenzone or octinoxate, the two UV filters most commonly banned in reef-protection legislation (such as Hawaii’s law). That said, the chemical filters they do use, particularly octocrylene, have drawn some environmental scrutiny. Octocrylene can degrade into benzophenone over time, and research on its effects on marine organisms is still developing. If minimizing environmental impact is a priority for you, Coola’s mineral formulas are the cleanest option for ocean and reef exposure.
Which Coola Products Are Safest
If your main concern is ingredient safety, Coola’s mineral, fragrance-free sunscreens are the strongest choice. They use the only two UV filters the FDA has fully cleared, they skip the fragrance that can irritate skin, and they avoid chemical filters that absorb into the bloodstream. For everyday use on the face, a mineral formula also tends to be gentler over months and years of repeated application.
Coola’s chemical formulas are not dangerous by any current evidence. Millions of people use avobenzone, homosalate, octisalate, and octocrylene daily without issues, and these ingredients have been in sunscreens for decades. The open question from the FDA is whether long-term, repeated absorption at high levels could pose a concern, and that question hasn’t been answered yet. For most adults using sunscreen as directed, the skin cancer risk from skipping sunscreen far outweighs the theoretical risks of chemical UV filters.
The practical takeaway: any Coola sunscreen you actually apply is safer than no sunscreen at all. But if you want the formula with the fewest open safety questions, reach for their mineral line.
