Could Zinc be absorbed through the skin via Sunblock?

Answer

Zinc is most likely absorbed into the body when zinc-containing sunscreens are applied to the lips. However, this would be a small amount under the recommended daily allowance (RDA) for zinc, which is 11 mg for adult men and 8 mg for adult women.
