How sunscreens work to protect your skin
Most sunscreens work by either reflecting or absorbing ultraviolet rays. Sunscreens that reflect light usually contain titanium dioxide or zinc oxide and have a whitish tint when they’re first applied. They immediately begin to protect your skin as soon as you put them on. And they continue to protect your skin for as long as they’re on.
Sunscreens that absorb ultraviolet rays usually contain chemical filters such as oxybenzone, octinoxate, octisalate, avobenzone or homosalate. These sunscreens tend to be clear when you put them on and may need to be reapplied more often than sunscreens that reflect light.
The different types of sunscreen available
There are many different types of sunscreen available on the market today. Each has its own set of benefits and drawbacks, so itufffds important to choose the right one for your needs.
Sunscreens can be divided into two main categories: chemical sunscreens and physical sunscreens. Chemical sunscreens work by absorbing the UV rays from the sun, while physical sunscreens work by reflecting the UV rays away from the skin.
Both types of sunscreen have their pros and cons. Chemical sunscreens are often more lightweight and easier to apply, but they can sometimes irritate sensitive skin. Physical sunscreens are usually a bit thicker in consistency, but they provide better protection against both UVA and UVB rays.
The best way to choose a sunscreen is to consult with a dermatologist or another medical professional. They can help you determine which type of sunscreen would be best for your particular skin type and needs.
How to choose the right sunscreen for your skin type
When it comes to sunscreen, there are a lot of options to choose from. How do you know which one is right for your skin type?
“The first thing you want to look for is the SPF, or sun protection factor,” says Dr. Dawn Davis, a Mayo Clinic dermatologist. “You want to choose something that has an SPF of 30 or higher.”
SPF measures how well a sunscreen protects your skin from ultraviolet B (UVB) rays. UVB rays are the main cause of sunburn and play a role in skin cancer.
You also want to make sure the sunscreen is broad spectrum, which means it protects against both UVB and ultraviolet A (UVA) rays. UVA rays penetrates deep into your skin and can lead to wrinkles, dark spots and other types of skin damage.
When it comes to applying sunscreen, more isn’t always better. “You want to use enough so that you have a teaspoon full for your face alone,” says Dr. Davis. “And if you’re going to be outside for an extended period of time, like at the beach or by the pool, you want to reapply every two hours.”
Dr. Davis also recommends using a lip balm or lipstick that has SPF in it as well. And if you’ll be outside during peak sunlight hours ufffd between 10 a.m. and 2 p.m ufffd seek shade when you can and wear protective clothing, like long-sleeved shirts and hats.
