Common sunscreens are formulated with large amounts of chemical sunscreen actives that are potential skin irritants and inflammatories. The risk of this inflammation increases on exposure to sunlight as the chemical sunscreen active goes through a chemical reaction. After sunscreen application, the severe skin redness and irritation that may result upon sun exposure is called a photosensitivity reaction. Eclipse SPF50+ contains no chemical sunscreen actives and only contains physical sunscreen actives. 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 this micro-encapsulation of actives, the anti-inflammatories, and antioxidants it contains.
