A. Great question. It seems everything contains a bit of sunscreen these days, whether it’s our mineral makeup or our lip balm (which is so important). With all of the layering, something has to give you protection if not double your protection, right? Unfortunately this is not the case. I consulted with Connecticut based dermatologist Dr. Loyd Godwin who indicated that you do not increase SPF by layering two different products. You should always use a sunscreen of at least 15 that provides both UVA and UVB protection.
