Difference Between Sunscreen and Sunblock

Skin Condition: Sunscreen vs Sunblock? Difference, Causes, Treatment.


Sunscreen is a commonly used type of sun protection. It filters or screens the sun's ultraviolet (UV) rays. This keeps most rays out but allows some to go inside. It can also be called a chemical sunscreen.

In simple words, sunscreen acts like a window shade, reducing (but not completely blocking) the effects of the sun's harmful rays. They usually contain organic compounds called benzophenones, which cause UVA radiation (which causes premature skin aging and wrinkles), and cinnamon and salicylate, which are also known as UVB radiation (the way sunburn and melanoma cause skin cancer. Causes) avoids. Rossi highly encouraged the use of sunscreen, known as "broad-spectrum.


Sunblock, on the other hand, reflects the sun's rays from the skin, causing the rays to penetrate the skin. This can be called physical sunscreen.

According to Rossby, sunblock usually contains protective elements such as titanium dioxide and zinc oxide, which appear white on the skin.

Sunblock is more effective

Blair Murphy-Rose, MD, FAAD, a board-certified dermatologist in New York City's Medical Dermatology and Cosmetic Surgery, says sunblock often contains zinc oxide and / or titanium dioxide. This can cause a physical barrier between the skin and harmful rays of the sun.

Sunblock is more effective than its sister sunscreen. In fact, zinc oxide and titanium dioxide are currently the only materials that are labeled as GRASE (generally recognized as safe and effective) to meet the requirements of the Food and Drug Administration.

Sunscreen contains many other chemicals such as avobenzone, octocrylene, homosalate, octylate, octinoxate and oxybenzone. Although, these provide the necessary sun protection for us, juries are still left out of how harmful they can be to our bodies by frequent use. In addition, sunscreen often needs to be reapplied more often and given more time to sleep into our pores.

Is sunscreen or sunblock better?

Doctor says that both types of sun protection have their own rules and icons. She recommends sunblock for people with sensitive skin or skin conditions, as some ingredients in chemical sunscreens may cause irritation or allergy. But in the end, the best sun protection product is the one you like to use and work for your needs.

Expert gives the sunblock an edge because it does not contain any chemical elements that can cause irritation.

All sunscreens and sunblock come with an SPF (sun protection factor). The American Academy of Dermatology recommends using a SPF of at least 30, which prevents 96% of UVB rays. But remember, while high SPF numbers block slightly more of the sun's UVB rays, no sunscreen can block 100% of them.
