Sunblock and sunscreen products are both popular for protecting the skin from the sun’s harmful rays, but they differ in how they provide that protection. Sunblock, as the name suggests, completely blocks UV rays from penetrating the skin, making it ideal for people who spend time in the water under the sun, such as boaters, divers, and athletes. Sunblock does not wash off easily, so it does not need to be reapplied as frequently. On the other hand, sunscreen filters the sun’s rays, allowing some ultraviolet rays to pass through and providing a tan. Sunscreen is typically less dense than sunblock due to its zinc oxide content and is generally less expensive. Understanding the differences between these two products is essential for those who frequently expose themselves to the sun.
Key Takeaways
- Sunblock completely blocks UV rays, while sunscreen filters them, allowing some to penetrate the skin.
- Sunblock is denser and more water-resistant than sunscreen, making it ideal for water-based activities.
