The benefits of an all-physical sunscreen, like Eclipse SPF50+, includes the use of the inert (does not irritate skin) sunscreen actives, zinc oxide and titanium dioxide. Although Extreme Protect SPF30 contains a chemical sunscreen active, it is micro-encapsulated so that it can be used in small amounts and protect the skin from skin sensitivities commonly experienced with brands containing large amounts of chemical sunscreen actives. Extreme Protect SPF30 is a favorite among those with sensitive skin because of the micro-encapsulation of actives, the anti-inflammatories, and antioxidants it contains.
