The EWG (Environmental Working Group) has investigated over 900 sunscreen products to come up with the sunsceen rating database linked here. Each product has a score from 0 to 10 where 0 to 2 indicates low hazard and 7 to 10 indicates high hazard.

This is not to say you should not use sunscreen. You should use sunscreen as recommended in the cosmeticsdatabase.com article as well as other sun-healthy tips.

Just have to buy one that is SPF 15 or high and listed in the database’s “best” list. See the chart matrix linked here and there are 28 products that are rated Low Hazard and Effective.

The EWG says “that 4 out of 5 sunscreen products offer inadequate protection from the sun, or contain ingredients with significant safety concerns.” And you can not just go by the brand name. EWG says “Some of the worst offenders are leading brands”. And some brands make many different products which ranges from 2 to 7 rating.
