How Sunscreen Functions

It’s no secret that sunscreen is important for protecting your skin from the harmful effects of the sun. But how does sunscreen actually work? In this article, we’ll take a look at the science behind sunscreen and how it helps to keep your skin safe from damage. Here is how sunscreen functions.

When UV rays from the sun hit your skin, they cause damage on a cellular level. This damage can lead to premature aging, wrinkles, and even skin cancer. sunscreen works by absorbing, reflecting, or scattering the UV rays before they can penetrate the skin.

There are two main types of sunscreen: chemical and physical. Chemical sunscreens work by absorbing the UV rays and converting them into heat, which is then released from the skin. Physical sunscreens work by reflecting or scattered the UV rays away from the skin.

Both types of sunscreen are effective at protecting the skin from damage, but they each have their own advantages and disadvantages. Chemical sunscreens are typically more water-resistant than physical sunscreens, but they can be more irritating to the skin. Physical sunscreens are less likely to irritate the skin, but they need to be reapplied more often.

With so many options available, it can be hard to know which sunscreen is right for you. The best way to choose is to read the label and find a sunscreen that offers broad-spectrum protection from both UVA and UVB rays. SPF, or sun protection factor, is also important. A higher SPF will provide more protection from the sun.

When applying sunscreen, be sure to use enough to cover all exposed skin. It is also important to reapply sunscreen every two hours, or more often if you are swimming or sweating. By following these simple tips, you can help keep your skin safe from the sun’s harmful rays.
