This SPF certainly is hydrating. The formula is a thicker cream base compared to the famous and personally loved: Hyaluronic Acid Watery Sun Gel. Unfortunately, this SPF is not a winner for me since it's formulated with only a single UV filter: Zinc Oxide. The initial white cast takes about 5 - 10 minutes to absorb to a sheer invisible matte finish. A good physical SPF option perhaps for sensitive skin, but not for me. Still MUCH love to ISNTREE. I'm such a fan of the brand!
