The investigation found that some sunscreens labeled as 'natural' or 'organic' actually contain ingredients that are known to be carcinogenic. The findings have raised concerns among consumers and health experts, prompting calls for better regulation of sunscreen products.
Can we infer that "All sunscreen brands on the market contain harmful chemicals."? Yes, no, or maybe?
