Summer is here, and with it comes the need to protect our skin from the sun’s harmful rays. Sunscreen is a must-have for beach trips, outdoor sports, and even daily commutes. But not all sunscreens are created equal. While typical chemical sunscreens promise to shield us from UV radiation, they come with hidden toxic dangers that many people are unaware of.
Typical chemical sunscreens contain a cocktail of synthetic compounds designed to absorb UV radiation. Common ingredients include oxybenzone, avobenzone, octinoxate, and homosalate. The toxic build-up of these chemicals over time, create interference to your detoxification system and your nervous system. Here are some reasons why these chemicals are harmful:
Hormone Disruption: Some chemical sunscreen ingredients, like oxybenzone, can mimic hormones in the body, potentially disrupting endocrine function. This can lead to a host of issues, from developmental problems in children to reproductive health concerns in adults.
Skin Irritation and Allergies: Chemical sunscreens can cause skin irritation, redness, and allergic reactions, particularly in individuals with sensitive skin.
Environmental Impact: When washed off in the ocean, chemical sunscreens contribute to coral reef bleaching and other marine life harm. Oxybenzone and octinoxate have been shown to damage coral DNA, impede reproduction, and contribute to coral death.
Free Radical Formation: Some chemical ingredients can break down in the sun, leading to the formation of free radicals. These unstable molecules can damage skin cells, accelerate aging and most alarmingly, lead to skin cancer.
In contrast to chemical sunscreens, mineral sunscreens use natural minerals like zinc oxide and titanium dioxide to physically block UV rays. Zinc oxide is particularly noteworthy for its effectiveness and safety. Here’s some of the benefits of using zinc based sunscreen:
Broad-Spectrum Protection: Zinc oxide provides broad-spectrum protection against both UVA and UVB rays. It sits on top of the skin and reflects, scatters, and absorbs UV radiation, offering a comprehensive shield.
Non-Toxic and Safe: Zinc oxide is non-toxic and non-irritating, making it suitable for all skin types, including sensitive skin and children’s delicate skin. It doesn’t penetrate the skin barrier, reducing the risk of systemic absorption and hormonal disruption.
Anti-Inflammatory Properties: Zinc oxide has anti-inflammatory properties, making it beneficial for those with skin conditions like rosacea or acne. It can help soothe the skin and reduce redness and irritation.
Environmentally Friendly: Unlike chemical sunscreens, zinc oxide is safe for marine life and doesn’t contribute to coral reef damage. It’s a reef-friendly option that helps protect our oceans.
Long-Lasting Protection: Mineral sunscreens often provide more stable and long-lasting protection as they are less likely to degrade in the sun compared to chemical sunscreens.
Switching to a zinc oxide mineral sunscreen is a simple yet powerful step you can take to protect both your health and the environment.
Here are some tips to make the transition:
1. Read Labels Carefully: Look for sunscreens labeled “broad-spectrum” and containing “non-nano zinc oxide” as the active ingredient. Avoid products with chemical UV filters like oxybenzone or octinoxate.
2. Choose SPF Wisely: An SPF of 30 is usually sufficient for most people. Higher SPF offers marginally better protection but can lead to a false sense of security, causing people to stay in the sun longer.
3. Apply Generously and Frequently: Apply sunscreen liberally to all exposed skin and reapply every two hours, or more often if swimming or sweating.
4. Combine with Other Sun Protection: Use additional protective measures such as wearing hats, sunglasses, and long sleeves. Seek shade during peak sun hours (10
AM to 4 PM).
5. Do your Research: The Environmental Working Group (EWG) has an entire database dedicated to sunscreens. They reviewed over 2000 sunscreens and over 257 brands, and currently have 230 recreational sunscreens that meet their safety criteria.

So, this summer, make the switch and enjoy the sun safely and responsibly. Your skin, your health, and our environment will thank you
