Protecting your skin from sun exposure is something that should not be overlooked. When shopping for sunscreen products, we often encounter the terms SPF (Sun Protection Factor) and PA (Protection Grade of UVA). However, what is the actual difference between them?
SPF measures how well a product can protect the skin from damage caused by UVB (Ultraviolet B) rays, which can lead to sunburn. The higher the SPF number, the longer you can be exposed to sunlight without getting sunburned. For example, SPF 30 means you can be exposed to sunlight 30 times longer than if you were not using sunscreen.
On the other hand, PA measures how well a product can protect the skin from UVA (Ultraviolet A) rays, which can cause skin aging and increase the risk of skin cancer. PA has levels ranging from PA+ to PA+++, with more plus signs indicating higher levels of protection.
It’s important to note that a good sunscreen product should protect the skin from both UVB and UVA rays. Therefore, when choosing a sunscreen product, make sure to check both the SPF and PA labels. The right choice will help protect your skin from the harmful effects of the sun.
Now, after understanding the difference between SPF and PA, you can make wiser choices in taking care of your skin from the adverse effects of the sun. Don’t forget to always apply sunscreen before outdoor activities to keep your skin healthy and protected.
