What is Reef-Safe Sunscreen?

Reef-safe sunscreens are formulated without harmful chemicals that can damage coral reefs and marine life. Certain ingredients found in many traditional sunscreens, such as oxybenzone and octinoxate, have been shown to negatively impact coral reefs and marine ecosystems. There is evidence that applying sunscreens containing these ingredients, especially before swimming, may contribute to coral bleaching and damage the reefs. 

Opting for reef-safe sunscreens protects your children's skin while also doing your part to preserve the oceans. Look for mineral-based sunscreens containing ingredients like non-nano zinc oxide and non-nano titanium dioxide.

These ingredients are less harmful to coral. The downside is that mineral-based sunscreens often leave a white “cast” on skin after application. That said, the best sunscreen is the one that you and your kids will actually use. Don’t sacrifice UV protection because you can’t find a reef-safe lotion that you like.

The Importance of Sunscreen for Kids

Sunscreen is essential because it prevents sunburn, minimizes skin damage, and reduces the risk of skin cancer. Sunburn not only causes immediate discomfort but also increases the risk of long-term skin damage. The harmful effects of the sun's rays can be even more significant for children, as just one blistering sunburn during childhood can double the risk of developing skin cancer later in life, according to the Skin Cancer Foundation. 

Incorporating sunscreen into your child's daily routine sets a healthy habit that will benefit them throughout their lives. Sun protection is not just for beach days or summer vacations but should be a year-round practice.

Remember, sunscreen is just one part of sun protection. Encourage kids to seek shade, wear protective clothing, and use hats and sunglasses to further shield their skin from the sun's rays. And don't forget to reapply sunscreen at least every two hours, especially after swimming or sweating.

How to Choose the Right Sunscreen

Look for a sunblock with an SPF of 30 or higher that offers broad-spectrum protection against both UVB and UVA rays. Opt for skin-friendly formulas that are hypoallergenic, fragrance-free, and dermatologist-tested. Additionally, consider water-resistant sunscreens when swimming or sweating.
