"The Sun Protection Factor (SPF) displayed on the sunscreen label ranges from 2 to as high as 50 and refers to the product's ability to screen or block out the sun's harmful rays. For example, if you use a sunscreen with an SPF 15, you can be in the sun 15 times longer that you can without sunscreen before burning. Consumers need to be aware that SPF protection does not increase proportionally with an increased SPF number. While an SPF of 2 will absorb 50% of ultraviolet radiation, an SPF of 15 absorbs 93% and an SPF of 34 absorbs 97%." from http://www.melanomafoundation.org/prevention/facts.htm

Yes, that is correct. Only the original jar and tube Carmex products do not contain SPF 15. Other varieties of Carmex, such as flavored or tinted lip balms, do contain SPF 15 for added sun protection.
