At Kiehl's, we hold firm in the knowledge that broad-spectrum sunscreen, which shields the skin from both UVA and UVB rays, is not only a vital, but crucial aspect of any daily skin preparation and the key to healthy, protected skin. We strongly recommend the regular use of sunscreens for the face, eye-area and body on a daily basis throughout the year. In fact, it is the cornerstone of every sound skincare regimen.
