pinkdervishP&R Day Cover SPF content
Dear Skin Biology,
Would you be able to measure the amount of titanium dioxide (percentage) in the P&R Day Cover? It would be helpful to know how much of an SPF is actually in the product.
Thank you.

Dr. PickartSPF is not exactly the blockage of sunlight. It is the redness that occurs after sun exposure.
