Difference Between Sunscreen and Sunblock

If you’re looking to protect yourself from ultraviolet radiation from the sun, there are two alternatives to try – sunscreen and sunblock. While both sound alike and have a similar purpose, they work differently. Hence you need to clearly distinguish between them. That’s where we come in. This article highlights the similarities and differences between sunscreen and sunblock. 

What is Sunscreen?

Like the name implies, sunscreen works to screen the skin from incoming UV rays. This whitish fluid turns transparent when rubbed into the skin. The best sunscreens are those that protect against UV-A and UV-B rays. It’s important to note that the active ingredient in sunscreen is octinoxate, oxybenzone, octisalate, avobenzone, homosalate, or octocrylene. 

What is Sunblock?

Unlike sunscreen, sunblock blocks out UV rays by reflecting them from the skin surface. They are also called physical sunscreens. Most sunblocks are made from titanium dioxide and zinc oxide. This is why these products have a considerably thicker appearance. Because of the physical properties of sunblocks, certain people may struggle to spread it on their body. It’s also considerably easier to notice when applied on the skin. 

Possible Similarities Between Sunscreen and Sunblock

There are a few similarities between sunscreen and sunblock, and it’s almost easy to ignore them. They include: 

• Sunscreen and sunblock are both designed to protect the skin from UV radiation, and any skin diseases associated with overexposure. 
• While the method of application may differ slightly, both products are used on the skin surface. 
• Both sunscreen and sunblock have a whitish appearance. 

What is the Difference Between Sunscreen and Sunblock?

There are a few notable differences between sunscreen and sunblock, starting from the manner of application to avoid UV radiation. Sunscreen only works when it’s absorbed into the skin. As a result, you may need to rub it. Often, it’s recommended to rub sunscreen till it changes from white to transparent. When applied correctly, sunscreen leaves no white residue on the skin. 

On the other hand, sunblocks are used to cover the skin. So, you don’t have to struggle to rub it in. However, you’ll need to cover all parts of your body evenly. Leaving just a small patch of skin exposed may result in a sunburn. Because of its application method, sunblocks leave a white residue on the skin surface. 

Furthermore, there’s a higher risk of side effects with sunscreens than sunblocks. Why? Sunscreens are absorbed into the skin and may easily irritate its layers. Additionally, sunscreens may also contain oil and fragrances that may cause acne.
