Warmer weather is on the horizon, and with it comes outdoor activities, beach trips and plenty of sunshine. While spending time under the sun can be enjoyable, it’s important to protect your skin and use a sunscreen spray, stick or lotion to protect against the sun’s harmful UV rays.
When it comes to sun protection, you may have heard the terms “sunblock” and “sunscreen” used interchangeably, but are they really the same thing? In this article, we’ll explore the difference between sunblock and sunscreen, their key features and why they are crucial for safeguarding your skin from the sun’s harmful rays.
Sunblock vs Sunscreen
Sunblock
Sunblock, also known as a physical sunscreen, contains mineral-based ingredients such as zinc oxide and titanium dioxide that work by sitting on top of the skin and physically blocking and reflecting UV rays. These ingredients can also provide broad-spectrum protection against both UVA and UVB rays. Sunblock is typically thicker in consistency and may leave a visible white cast on the skin due to the mineral particles. It’s ideal for people with sensitive skin or those who are prone to skin allergies, as it is less likely to cause irritation.
Sunscreen
On the other hand, sunscreen, also known as chemical sunscreen, contains organic compounds such as avobenzone, octinoxate and oxybenzone that work by absorbing UV rays and converting them into heat, which is then released from the skin. Sunscreen is usually thinner in consistency and tends to be transparent on the skin, without leaving a visible white cast. It provides effective protection against both UVA and UVB rays and is often preferred for its ease of application and lightweight feel.
Choosing the Right One for You
It’s good to know that both sunblock and sunscreen undergo testing for safety, efficacy and approval by the U.S. Food and Drug Administration (FDA). And when choosing a sun protection product, it’s essential to look for the term “broad-spectrum” on the label, which indicates that it protects against both UVA and UVB rays. It’s also crucial to select a product with a high SPF (Sun Protection Factor) of 30 or higher, as this indicates the level of protection against UVB rays.
Just keep in mind that no sunscreen or sunblock can provide 100% protection against UV rays. Plus, they require reapplication every two hours, or immediately after swimming or sweating for optimal sun protection.
So, which one should you choose, sunblock or sunscreen? Ultimately, it depends on your personal preference, skin type and specific needs. Sunblock starts working immediately and may be a better option for those with sensitive skin or skin allergies. Sunscreen usually takes 15-20 minutes to absorb into the skiing, but it may be better for those who desire ease of application and a transparent finish.
Regardless of your choice, the most important thing is to make sun protection a non-negotiable part of your daily skincare routine, especially during the sunnier months.
Conclusion
Understanding the difference between sunblock and sunscreen is essential for effective sun protection. Sunblock and sunscreen both serve the same purpose — to protect your skin from harmful UV rays — but they differ in their chemical or mineral ingredients, consistency and application. Whether you prefer the physical barrier of sunblock or the lightweight feel of sunscreen, the key is to choose a broad-spectrum product with a high SPF and reapply regularly for optimal sun protection.
