sunscreen is not cope.
- sunlight UVA/UVB radiation is proven to cause DNA damage to skinn cells which become unable to produce collagen
- sunscreen 30 SPF is proven to block 99% of UVA and UVB sunlight radiation
- after using sunscreen you become unable to produce vitamin D, however you can just take it from supplements once a day

I never take sun in my face in winter (most of the time) and use a hat in summer, i just get sun while bathing, which is like 1 hour a day in summer months.
