Ozone is a molecule made of oxygen atoms. There are 3 atoms in ozone, unlike the oxygen molecule, which has 2 oxygen atoms. It forms in a lot of ways. One way is when ultraviolet sunlight breaks up oxygen atoms and they combine into ozone. That is what happens in Earth's stratosphere, where our ozone layer is. That happens on Mars too, and Mars has ozone. There is much less oxygen to start with, so there is not very much ozone on Mars. It doesn't form a layer there, it reaches all the way to the surface. And there is little enough ozone that far more ultraviolet light reaches the surface of Mars than the surface of Earth. Basically if you go to a Marsian beach to get a tan you would get sunburns pretty fast.

Mars does not have an ozone layer because Mars has virtually no oxygen (0.15%) in its atmosphere (which is much much thinner than ours to begin with).
