- So the agency ditched the stars and instead will tell manufacturers that if they wish to label their products as offering "broad spectrum" protection they must make their defense against UVB and UVA radiation proportional.
- Any product that fails to offer proportional protection or has an SPF of 2 to 14 must include a warning that the product has not been shown to help prevent skin cancer or early skin aging.
