The ZO Smart Tone Broad Spectrum SPF 50 sunscreen is quick-drying and non-greasy. Your skin is shielded against the again effects of HEV (high-energy invisible) light which can age your skin. This sunscreen also offers broad-spectrum protection against UVA and UVB rays. For outdoor activities, this is a great option as it is water and perspiration resistant while also hydrating the skin to prevent dryness. Using ZO’s exclusive oxybenzone free ZOX12TM complex, which is engineered for 12-hour time-release, this helps to shield your skin from harmful infrared (IR-A) rays.
