Sunscreens protect the skin and reduce the risk of skin cancer

• Every year, over 300,000 new cases of skin cancer are registered.
• Sunscreens with SPF 30 provide sufficient protection.
• Scientists are researching new ingredients for sunscreens.

Every year, over 300,000 new cases of skin cancer are diagnosed, but they can be prevented. In particular, this may be due to the effectiveness of sunscreens that have long been available. However, due to myths and misconceptions, spread on social media, some people may refuse to use them.

It is important to note that ultraviolet (UV) radiation, which penetrates the Earth's atmosphere, can cause skin damage. There are two main types of UV: UVA, which penetrates deep into the skin layers, and UVB, which causes sunburn.

Sunscreens are divided into two types: "chemical" and "physical." Chemical sunscreens contain organic compounds that absorb UV radiation, while physical sunscreens use titanium dioxide or zinc oxide to block UV. None of the creams can completely block UV radiation, but they significantly reduce its impact.

Dermatologists recommend using sunscreen with an SPF of at least 30, as it provides sufficient protection. At the same time, it is important to note that many people do not apply enough cream, which reduces its effectiveness.

It is believed that creams with higher SPF provide better protection, but the difference between SPF 30 and SPF 50 is not significant. It is important to use SPF 30 daily, rather than relying on occasional use of higher SPF 100.

Moreover, there is a growing interest in natural sunscreens, which use natural ingredients. However, their effectiveness is often questionable, and experts recommend being cautious with homemade recipes.

Researchers are also investigating the possibility of using plant-based ingredients to create new types of sunscreens that may reduce dependence on chemical substances.
