The UV rays of the sun are a part of the electromagnetic spectrum. These are high energy radiations. They build and destroy ozone both.
The epidermis is the outer layer of the skin that acts as armor for the human body. It can keep out dust, water, germs, and the suns ultra-violet rays. It also gives you the sense of touch including pain pressure and temperature. It is composed of 4-5 layers.
SPF 25 sunscreen blocks about 96% of the sun's ultraviolet rays from reaching the skin. The remaining 4% can still penetrate the skin and cause damage, so it is important to reapply sunscreen regularly and practice other sun protection measures.

Ozone gas in the Earth's stratosphere acts as a shield against the sun's ultraviolet radiation by absorbing and filtering out a significant portion of harmful UV rays before they reach the Earth's surface. This helps protect organisms and ecosystems from the harmful effects of UV radiation.
The thing which protects us from suns UV rays is the ozone. It is an allotrope of oxygen element.
