The Birch Moisturizing Mild-Up Sunscreen SPF 50+, PA++++ is a moisturizing sunscreen designed to protect sensitive skin by reflecting ultraviolet rays while locking in moisture and brightening the complexion. It is packed with amino acids, minerals, and Birch Sap vitamins that form a moisture barrier to protect the skin from drying out. The lotion-type consistency is easy to blend and allows for easy layering throughout the day.
