TiO2 Sunblock SPF 30 provides protection against both ultraviolet rays type A and B (UVA/UVB). This is very important because both UVA and UVB can damage the skin and most sunscreens only provide protection over a limited spectrum of sun ray types. This product achieves an ultra-broad protection by combining several types of active ingredients for maximum and durable coverage. While it does not contain as many hydrating ingredients asAdvanced Face Lotion, it does contain light moisturizing and anti-aging elements so it can be used in place of the lotion for normal to oily skin.
