As summer approaches, the excitement builds with thoughts of longer days, short-sleeved tops, and leisurely beach days. However, the sunny season also brings challenges, especially when it comes to our skin care. The warm weather not only invites us to wear less but also exposes us to harmful UV rays, making SPF an essential part of our summer skin care routine.
Many people think of SPF as something only needed at the beach or during prolonged sun exposure. Yet, it’s equally important for everyday use. Simple activities like walking to and from our cars can expose our skin to significant UV damage, affecting areas like our face, neck, and arms. So, what should we keep in mind when choosing a summer SPF? Let’s delve into it.
Physical vs. Chemical Sunscreen: In the U.S., chemical sunscreens are widespread and easy to find in grocery and drugstore aisles, which might suggest they are the preferred choice. However, physical sunscreens are actually better for your skin, your health, and the environment. Here’s why:
- Mechanism of Action: Chemical sunscreens absorb UV rays into your skin and convert them into heat, which is then released. This can heat up the dermis, causing irritation, redness, and discomfort. Physical sunscreens, on the other hand, reflect UV rays away from your skin like a mirror, preventing them from penetrating the skin at all.
- Skin Irritation: Chemical sunscreens can irritate the skin, whereas physical sunscreens are generally soothing and calming.
- Application: Chemical sunscreens need to be washed off and reapplied to be effective again because the old residue can interfere with the reapplication. Physical sunscreens can be layered without the need to wash off the previous application, making them more user-friendly.
UVA/UVB Protection: It’s crucial to choose broad-spectrum SPF products that protect against both UVA and UVB rays. UVB rays, more prominent during the hottest and brightest months, are primarily responsible for sunburn. UVA rays, however, are more insidious; they’re present all year round, can penetrate glass and clouds, and contribute to skin aging by breaking down collagen and elastin. They also play a significant role in various types of skin cancer. Ensuring your SPF protects against both types of rays is vital for maintaining healthy skin.
In summary, understanding the differences between physical and chemical sunscreens and the importance of broad-spectrum protection will help you make informed choices about your summer skincare, keeping your skin safe and healthy during the sunniest part of the year.
