Acne Shield IQ is a lightweight SPF 45 which contains an innovative blend of active ingredients. It protects skin from multiple extrinsic factors known to cause premature aging, including UVA, UVB and infrared radiation. Clear Defense SPF 45 delivers a new strategy in sun protection, providing the highest possible level of protection while restoring youthfulness to the skin. Derived from knotweed extract, our botanically-based active is the first of its kind, preventing damage from infrared radiation, which is believed to be just as detrimental to skin health as UVA and UVB. This fast-absorbing SPF also features a high level of niacinamide to promote a smoother, clearer complexion.
