UV reach us by ozone hole. It is the thinning of ozone layer.
By being transmitted through the atmosphere.

Ozone absorbs the UV to decompose. It thus protects us.
The cream is opaque and reflects the UV rays before they reach the skin's surface.
Ozone is protecting and will protect us. The protection is against UV.
Yes the ozone layer protects us from uv (ultra violent) rays

The ozone protects us from much UV radiation. It is present as ozone layer.
Ozone gas protects us from the UV rays. These are fatal UV rays from the sun.
