Numbuzin - No.1 Clear Filter Sun Essence SPF 50+ PA ++++ is a lightweight and clear sun essence designed to protect your skin from harmful UV rays and environmental pollutants. It is a broad-spectrum sunscreen that provides high protection against both UVA and UVB rays, with a sun protection factor (SPF) of 50+ and a PA++++ rating, which is the highest protection rating available! It does not leave your face feeling sticky or leave behind a residue. Honestly, after I apply it I can't even tell that it's there at all. It is a great addition to my daily skincare routine!
