Sunscreen is the first line of protection against skin cancer. It protects against UVB and UVA rays that can cause skin cancer. Sunscreen also prevents wrinkles, age spots, and other signs of skin aging.
Sunscreens are evaluated based on their SPF or sun protection factor. The higher the number, the more UVB protection they provide. The FDA has approved a new sunscreen rating system called PA or Protection Grade that takes into account both UVA and UVB rays to help people find a sunscreen with the right level of protection for their needs.
Sunscreen is a topical ointment that protects the skin from sunburn by blocking some of the ultraviolet (UV) radiation from reaching the skin. It is a form of photoprotection.
The best sunscreen for you depends on your skin type and how much time you spend outside. There are many types of sunscreen, including physical blocks, chemical blocks, mineral blocks, and organic sunscreens.
The main difference between this type of sunscreen and an SPF 30 sunscreen is that it provides better UVA (aging) protection than a regular SPF 30 does.

The sun is the strongest source of ultraviolet (UV) radiation on Earth. The UV rays from the sun can be divided into three types: UVA, UVB, and UVC.
The UVA rays are the most abundant, but they do not cause sunburn or tanning. They penetrate deep into the skin and are responsible for aging skin and wrinkles.
UVC rays are rare and don’t reach Earth’s surface since they are absorbed by ozone in the upper atmosphere.
UVB rays cause sunburns, tanning, and skin cancer when they reach Earth’s surface.
There is no such thing as a 100% effective sunscreen that will completely block all UV radiation from reaching your skin! This is because some UV radiation will always get through to your skin.
What are the types of sunscreens?
There are two types of sunscreens: chemical and physical.
Chemical sunscreens use dozens of ingredients that are absorbed into the upper layers of the skin when applied. They react with the skin to absorb UV rays and convert them into energy before damaging the skin.
Physical sunscreen, sometimes called “natural or mineral” sunscreen, consists of two components: zinc oxide and titanium dioxide. Together, these elements settle on the skin and deflect or reflect sunlight.
Think of physical sunscreen as a shield, while chemical sunscreens are absorbed into the skin. Both components work well to protect against UVA and UVB (broad spectrum) rays. Physical sunscreens are thick so they can turn white on the skin.
Sunscreen is one of the most important things you can use to protect your skin from the sun.
Sunscreen is not just a layer that sits on your skin. It goes deep into your skin to protect it from UV rays. The best sunscreen contains zinc oxide, which provides broad-spectrum protection against both UVA and UVB rays.
