With so many SPFs on the market, it can be difficult to know which one is right for your skin. So where to begin? Firstly it’s important to note there are two main types of sunscreen; chemical SPFs and physical SPFs, that function in different ways, but both provide protection from the sun. When searching for your ultimate SPF, the best place to start is by understanding the difference between a chemical and physical sunscreen.
What is a chemical SPF?
To put it quite simply, chemical sunscreens absorb into the skin, and physical sunscreens sit on top of the skin. Chemical sunscreens often include ingredients such as avobenzone, oxybenzone or octinoxate. These ingredients will be absorbed into the skin, the UV rays then penetrate the skin and are absorbed by the chemical SPF, which converts the UV rays into heat, and then releases them from the body, preventing sun damage. Our skin is clever huh?
What is a physical SPF?
Physical sunscreens sit on top of the skin and form a barrier, reflecting the UV rays, and preventing them from penetrating the skin. Titanium dioxide and zinc oxide are the key ingredients in physical sunscreens, so if you’re ever unsure whether a sunscreen is physical or chemical, just check the ingredients listed on the product packaging. Now you have the inside scoop on SPF you can choose one that’s right for your skin.
Which is better, chemical or physical sunscreen?
So now you know the difference between the two sunscreens, it begs the question of which type is best for your skin? Well, this all depends on your skin type. Typically people with sensitive or dry skin are best suited to a physical sunscreen, this type of sunscreen is usually less irritating and a thicker consistency for increased hydration.
Due to the thickness of the physical sunscreens many brands have formulated tinted or matte versions to reduce the white cast that some sunscreens can create, so you can experience a smoother, more even appearance. This type of sunscreen is also great for using under makeup!
