It’s actually much more that the ozone layer, which filters uv, is much thinner than it was even 60-70 years ago. The ozone layer might be growing again, but at a very slow pace.
Simple fact is, we’re much more exposed to uv than prior generations.

Which corresponds with the ozone layer being about 5% thinner:

Not good (or good for us) but also not a huge huge change, since we stopped the thinning of the ozone layer mostly in time.
