Florida's "Natural" Sunscreens: The Humid Truth Revealed

Are you tired of sunscreen that feels like you’re coated in grease, only to wash off the second you step outside in Florida’s humidity? Do you want to protect our precious coral reefs while protecting your skin? You’re not alone. Finding a truly reef-safe, effective sunscreen in the Sunshine State can feel like searching for buried treasure.

Let’s cut through the marketing hype and get real about sunscreen in Florida.

Many sunscreens claim to be “reef-safe” or “natural,” but a closer look at the ingredients often reveals otherwise. Oxybenzone and octinoxate are the notorious culprits, but other chemicals like octocrylene and homosalate are also under scrutiny for their potential harm to marine life. These chemicals are often found in popular brands readily available in drugstores from Miami to Jacksonville.

So, how do you navigate the sunscreen aisle and choose a product that actually protects both you and the reefs?

First, become a label detective. Don’t just trust the front of the bottle. Scrutinize the ingredient list. Look for sunscreens that use mineral-based active ingredients like zinc oxide and titanium dioxide. These minerals create a physical barrier against the sun’s rays, rather than being absorbed into the skin like chemical sunscreens.

Second, beware of “greenwashing.” Just because a sunscreen has a picture of a coral reef on the label doesn’t mean it’s actually reef-safe. Many companies use misleading marketing tactics to capitalize on the growing demand for eco-friendly products.

Third, consider the SPF level. While a higher SPF might seem better, it’s important to understand that SPF only measures protection against UVB rays, which cause sunburn. It doesn’t measure protection against UVA rays, which contribute to premature aging and skin cancer. Look for “broad spectrum” sunscreens that protect against both UVA and UVB rays. An SPF of 30 to 50 is generally sufficient for most people.

Now, let’s talk about the Florida factor: humidity and sweat. This is where many “natural” sunscreens fall short. They can feel heavy, greasy, and prone to running, leaving you with a white cast and uneven protection.

One solution is to look for mineral sunscreens specifically formulated for active lifestyles. These sunscreens often contain ingredients like silica or tapioca starch to help absorb excess moisture and prevent the dreaded “slip-and-slide.”

Another option is to apply your sunscreen in layers. Instead of slathering on a thick coat all at once, apply a thin layer, let it absorb for a few minutes, and then apply another layer. This can help the sunscreen adhere better to your skin and prevent it from feeling greasy.

Let’s compare some popular brands you might find in a Walgreens in Tallahassee or a CVS in Orlando.

Badger Balm: This brand offers a range of mineral sunscreens with simple, natural ingredients. However, some users find it to be a bit thick and difficult to apply.
Thinkbaby/Thinksport: These sunscreens are popular choices for families because they are effective, reef-safe, and relatively affordable. They tend to be less greasy than some other mineral sunscreens.
Raw Elements: This brand offers a tinted mineral sunscreen that can help minimize the white cast often associated with mineral sunscreens. It’s also water-resistant and long-lasting.
Stream2Sea: This brand is specifically formulated to be reef-safe and biodegradable. It’s a good option for divers and snorkelers.

But what if you want even more control over the ingredients in your sunscreen? Consider making your own!

Here’s a simple DIY sunscreen recipe using accessible ingredients:

2 tablespoons zinc oxide powder (non-nano)
1/4 cup coconut oil
1/4 cup shea butter
2 tablespoons beeswax
Optional: a few drops of essential oil for fragrance (lavender, chamomile, or carrot seed oil are good choices)

Instructions:

Melt the coconut oil, shea butter, and beeswax in a double boiler or a heat-safe bowl set over a pot of simmering water.
Once melted, remove from heat and let cool slightly.
Slowly whisk in the zinc oxide powder until it is fully incorporated. Be careful not to inhale the powder.
Add essential oils, if desired.
Pour the mixture into a jar or container and let it cool completely.

This DIY sunscreen will be thicker than commercial sunscreens, so you’ll need to rub it in well. It’s also important to note that the SPF of homemade sunscreen is difficult to determine accurately. It’s estimated to be around SPF 20-30, but it’s best to reapply frequently, especially after swimming or sweating.

Application is key, regardless of which sunscreen you choose.

Apply sunscreen liberally 15-30 minutes before sun exposure.
Reapply every two hours, or immediately after swimming or sweating.
Don’t forget to apply sunscreen to often-overlooked areas like your ears, neck, and the tops of your feet.
Use a shot glass-sized amount (about an ounce) to cover your entire body.

One common mistake is not applying enough sunscreen. People often underestimate the amount needed to achieve the stated SPF protection. Another mistake is not reapplying frequently enough. Sunscreen can wear off due to sweat, water, and friction.

Another challenge is the white cast that mineral sunscreens can leave on the skin. To minimize this, choose a tinted mineral sunscreen or look for sunscreens that use micronized zinc oxide. However, be aware that micronized zinc oxide may be more easily absorbed into the skin, which some people prefer to avoid.

Finally, remember that sunscreen is just one part of sun protection. Wear protective clothing, seek shade during peak sun hours (10 am to 4 pm), and wear a hat and sunglasses.

Living in Florida means embracing the sun, but it also means taking sun protection seriously. By choosing reef-safe sunscreens, applying them correctly, and practicing other sun-safe behaviors, you can protect your skin and our precious coral reefs. So, next time you’re in a Publix in Sarasota or a Winn-Dixie in Daytona Beach, take a moment to read the labels and make an informed choice. Your skin and the planet will thank you.
