For two of the last five years, SolBar has been the number one recommended sunscreen from over 50 different brands in our independent, national survey of U.S. dermatologists. Each SolBar sunblock offers a different combination of active ingredients. SolBar Zinc uses zinc oxide, a physical blocker, to enhance UVA protection, while SolBar Avo uses avobenzone (also called Parsol 1789), a chemical absorber, for enhanced UVA protection. SolBar SPF 50 provides a very high level of protection against UVB. Produced by Person & Covey of Glendale, California, SolBar offers the best SPF 30+ multi-spectrum formulations.
