Sunscreens Exposed: Balancing the Sunny-side Benefits with the Shady Consequences for You and Our Planet

I adore the sun. It just makes me feel content to see it and feel its rays tickle my skin. The sun gives us warmth and light, makes our food grow and most importantly, it helps our bodies make the most optimal Vitamin D naturally. But, unfortunately the sun can also be harmful for our health. In the United States, skin cancer is the most common type of cancer. So rather than hide in the basement we slather on some sunscreen to protect us from the harmful UV rays and we are good to go, or are we? There has been a lot of press lately about the dangers of using sunscreen. Our skin is the largest organ and it will absorb almost anything we put on it. With so much controversy about sun protection, it’s easy to be skeptical of the effectiveness and safety of sunscreen altogether. Let’s delve into the world of suntan lotion and explore its advantages, disadvantages, and the ingredients that make it healthy or unhealthy.

Advantages of Sunscreen:

1. UV Protection: The primary benefit of sunscreen is shielding your skin from the damaging effects of ultraviolet (UV) radiation. Sunscreens with broad-spectrum coverage defend against both UVA and UVB rays, reducing the risk of sunburn, premature aging, and skin cancer.
2. Skin Defense: Mineral sunscreens can act as a barrier, preventing harmful substances and pollutants from penetrating your skin. It aids in reducing the risk of skin irritation, allergies, and certain dermatological conditions.
3. Prevents Uneven Skin Tone: Regular use of sunscreen helps prevent the formation of dark spots, hyperpigmentation, and uneven skin tone caused by excessive sun exposure.
4. Anti-Aging Benefits: By shielding your skin from UV radiation, sunscreen can help maintain a youthful appearance by minimizing the development of wrinkles, fine lines, and sagging skin.
5. Convenient Protection: Sunscreen comes in various forms, such as lotions, creams, sprays (may not be the best option),      and sticks, making it easy to apply and reapply throughout the day. It allows for hassle-free protection whenever you step out into the sun.

Ingredients: The Good, the Bad, and the Controversial:

Healthy Ingredients:

Zinc Oxide and Titanium Dioxide: These mineral-based ingredients offer broad-spectrum protection and are less likely to cause skin irritation or allergic reactions. They work by reflecting UV rays away from the skin.

Unhealthy Ingredients:

1. Oxybenzone and Octinoxate: These chemical filters are effective at absorbing UV rays but have raised concerns due to potential hormonal disruption and coral reef damage. They are often found in conventional sunscreens and can be harmful to marine ecosystems.
2. Retinyl Palmitate: A form of vitamin A, this ingredient has been linked to potential skin sensitivity and an increased risk of sunburn. It is advisable to avoid sunscreens containing this ingredient.
3. Avobenzone: Research shows avobenzone reacts with chlorine and might cause toxic reactions and cause skin allergies. Avobenzone degrades when it is exposed to the sun which results in harmful free radicals being released into the body.
4. Ecamsule: Ecamsule (trade name Mexoryl SX) also can be absorbed through the skin. It has the potential to cause rare short-term effects such as dermatitis, dry skin, acne, itching and redness.
5. Benzene: This compound is found in many spray-style or aerosol sunscreens. Long-term exposure to benzene can lessen your ability to fight off infection and lead to fertility issues, anemia and leukemia. Benzene is commonly used for industrial purposes such as in the manufacturing of plastics, rubber, pesticides and more. And it’s found naturally found in gas, crude oil and cigarette smoke.
6. Parabens: These are known endocrine disruptors that can mimic estrogen in the body. Studies have shown that parabens can affect the mechanisms of normal breast cells and potentially influence their abnormal growth.

Dangers of Common Sunscreen:

1. Allergic Reactions: Some individuals may experience skin irritation or allergic reactions to certain sunscreen ingredients. It’s essential to identify any personal sensitivities and choose sunscreens tailored to your needs.
2. Environmental Impact: Oxybenzone and octinoxate, found in many conventional sunscreens, pose a threat to coral reefs and marine life. These chemicals can contribute to coral bleaching, disrupt ecosystems, and harm underwater habitats. Opting for reef-safe sunscreens without these ingredients can help mitigate this environmental impact.
3. False Sense of Security: Relying solely on sunscreen for sun protection can create a false sense of security. It’s important to remember that sunscreen is just one part of a comprehensive sun protection strategy. Seeking shade, wearing protective (UV) clothing, using hats and sunglasses and the time of day you get sun exposure are also vital in minimizing sun damage. 

Also, beware of Vitamin D Deficiency: Excessive and indiscriminate use of sunscreen may inhibit the production of vitamin D, which plays a crucial role in bone health, immune response and many other vital functions. However, it’s essential to strike a balance between sun exposure for vitamin D synthesis and the need for UV protection.

What ingredients should you look for?

Mineral-based sunscreens as opposed to chemical sunscreens. The two most common ingredients in mineral sunscreens, titanium dioxide and zinc oxide, are the only sunscreen ingredients considered generally safe and effective by the FDA. They provide:

1. Broad-spectrum protection: Mineral sunscreens provide protection against both UVA and UVB rays. They form a physical barrier on the skin that reflects or scatters the sun’s rays, offering broad-spectrum protection.
2. Lower risk of skin irritation: Mineral sunscreens are generally well-tolerated and are less likely to cause skin irritation or allergic reactions compared to chemical sunscreens.
3. Safer for the environment: Chemical sunscreens can have harmful effects on marine life and coral reefs when they wash off into the water. Mineral sunscreens are considered more environmentally friendly.

But sunscreen isn’t the only answer. It’s also important to be mindful of when and how long we spend in the sun. The sun’s rays are strongest between 10 a.m. and 4 p.m., so try to seek shade during those hours.

Remember, everyone’s skin is different. Some people are more sensitive to the sun than others. If you have fair skin, light hair, or a history of sunburns, you might need to be extra careful.

In a nutshell

The sun is awesome and it’s powerful. And we need to be aware of its potential effects on our skin. It’s only logical to use common sense and read sunscreen labels carefully before putting anything on our skin (JUST LIKE FOOD LABELS). The right sunscreen is undeniably beneficial for protecting our skin from harmful UV radiation and maintaining its health. However, it’s important to be aware of both the advantages and disadvantages it presents. Opting for sunscreens with healthier ingredients, such as zinc oxide and titanium dioxide, can provide effective protection while minimizing potential risks. Additionally, choosing reef-safe sunscreens helps preserve our marine ecosystems. Remember, responsible sun exposure, alongside sunscreen, is key to striking the right balance between sun protection and vitamin D synthesis. So go ahead, embrace the sun but use your common sense from getting roasted.

I really like the Sunscreen products by Blue Lizard,  and in particular this one for sensitive skin, they are all broad spectrum, mineral based sunscreens free of fragrances and parabens. Another great sunscreen is Two Peas Organics which is an excellent product and healthy for you and the environment.
