As the sun shines brighter and the temperatures rise, it's essential to protect your skin from harmful UV rays. However, not all sunscreens are created equal when it comes to their impact on the environment. In this blog post, we'll explore the importance of choosing eco-friendly sunscreens and provide you with a comprehensive guide to making sustainable choices for sun protection.


1. The Environmental Impact of Traditional Sunscreens:

Concerns about the safety of sunscreen products have been raised lately due to the absorption of sunscreen ingredients into our bodies. You may have heard about the ban on oxybenzone (BP-3) and octinoxate (OMC) in Key West and Hawaii because of their harmful effects on marine ecosystems.

  • How sunscreen chemicals can affect marine life:

  • Green Algae: Can impair growth and photosynthesis.

  • Coral: Accumulates in tissues. Can induce bleaching, damage DNA, deform young, and even kill.

  • Mussels: Can induce defects in young.

  • Sea Urchins: Can damage immune and reproductive systems, and deform young.

  • Fish: Can decrease fertility and reproduction, and cause female characteristics in male fish.

  • Dolphins: Can accumulate in tissue and be transferred to young. (source)

But what about their impact on our health? Let's dig into the current evidence and see what it tells us.

So, we did some digging and found 29 studies that shed light on the association between these ingredients and our well-being. Good news is that there doesn't seem to be any adverse effects on fertility, hormone levels, adiposity, fetal growth, child development, or sexual maturation when it comes to elevated levels of BP-3. However, there are some reports suggesting a potential link between BP-3 and thyroid hormones, testosterone levels, kidney function, and pubertal timing. But hold on, more research is needed to confirm these associations.

When it comes to OMC, it seems to have no impact on thyroid and reproductive hormone levels based on the available studies. But we need more comprehensive research to fully understand the long-term risks of BP-3 and OMC exposure from sunscreen use.

In a nutshell, the current evidence doesn't provide a clear-cut answer about the potential health risks associated with elevated systemic levels of BP-3 or OMC. There are conflicting findings among studies, and we need more robust research, like well-designed longitudinal randomized controlled trials, to get a better grasp of the situation.

2. Understanding Eco-Friendly Sunscreens:

In recent years, the concept of eco-friendly sunscreens has gained traction as people become more conscious of their environmental impact. But what exactly are eco-friendly sunscreens, and how do they differ from traditional ones? Let's dive in and find out!

On the other hand, eco-friendly sunscreens take a different approach than traditional chemical sunscreens. They prioritize using mineral-based ingredients like zinc oxide and titanium dioxide. These minerals create a physical barrier on the skin's surface that reflects and scatters UV rays away from the skin, offering broad-spectrum protection. Unlike their chemical counterparts, mineral-based sunscreens are considered reef-safe and do not contribute to coral bleaching or other harm to marine life.

One of the key benefits of eco-friendly sunscreens is their biodegradability. Since they contain natural and mineral-based ingredients, they break down more easily in the environment compared to synthetic chemical sunscreens. This means that when you go for a swim or take a shower, eco-friendly sunscreens are less likely to leave behind harmful residues that can pollute water bodies and affect aquatic organisms.

Furthermore, eco-friendly sunscreens often come in packaging that is designed to be more sustainable. Many brands opt for recyclable or biodegradable materials to minimize their environmental footprint. They may also incorporate other eco-friendly practices into their manufacturing processes, such as reducing water usage or supporting ethical sourcing of ingredients.

Choosing an eco-friendly sunscreen not only protects your skin from harmful UV rays but also helps to preserve the health of our oceans and marine life. By making a conscious choice, you can enjoy the sun responsibly and contribute to a more sustainable future.

Remember, when shopping for sunscreen, look for key phrases like "reef-safe," "mineral-based," or "biodegradable" on the packaging. These indicators will guide you towards eco-friendly options that align with your values of protecting both your skin and the environment.

3. Other Sun Protection Strategies:

In addition to using eco-friendly sunscreens, there are several other sun protection strategies you can incorporate into your routine to stay safe under the sun.

These strategies not only complement the use of sunscreen but also offer additional layers of protection. Let's explore some of these practices:

  1. Seek shade: When the sun is at its strongest, typically between 10 am and 4 pm, seek shade whenever possible. This can be under trees, umbrellas, or any covered areas that provide shelter from direct sunlight.

  2. Wear protective clothing: Covering up with clothing is an effective way to shield your skin from the sun's harmful rays. Opt for lightweight, loose-fitting garments that cover as much skin as possible. Look for clothing with UPF (Ultraviolet Protection Factor) labels for enhanced sun protection.

  3. Wear a wide-brimmed hat: A wide-brimmed hat provides extra protection for your face, neck, and ears. Choose a hat with a brim that is at least 3 inches wide to ensure adequate coverage.

  4. Wear sunglasses: Protecting your eyes from harmful UV rays is just as important as protecting your skin. Look for sunglasses that offer 100% UV protection to shield your eyes from both UVA and UVB rays.

  5. Practice sun-safe behaviors: Remember to be mindful of your sun exposure habits. Avoid unnecessary sun exposure, especially during peak hours. If you're planning outdoor activities, try to schedule them earlier in the morning or later in the afternoon when the sun is less intense.

  6. Stay hydrated: Drinking plenty of water helps to keep your body hydrated and supports your skin's overall health. Hydrated skin is more resilient and less prone to sun damage.

  7. Regularly check your skin: Perform self-examinations of your skin to detect any changes or irregularities. If you notice any new or changing moles, spots, or lesions, consult a dermatologist for further evaluation.

No single sun protection method is foolproof, which is why a combination of strategies is recommended for comprehensive sun safety. By incorporating these practices into your daily routine, you can enjoy the outdoors while minimizing the potential risks associated with sun exposure.

4. Korean Reef-Safe Sunscreen

Did you know that the term "Reef-Safe" isn't regulated? That means any company can use it without facing any consequences. It's often used as a clever marketing tactic on sunblock products. But here's the thing: just because they claim to be "reef-safe" doesn't mean they're actually safe for coral reefs. It's more like the ingredients they're using haven't been proven to harm reefs (at least not yet!). So, it's important to be aware and do your own research when choosing products that truly prioritize our beautiful reefs. (source)
