You really are clueless.

Look up titanium dioxide and aluminum - both in sunscreens. Read "Exposing the Hazards of Sunscreen" by Elizabeth Plourde, CLS, NCMP, PhD. You can find it published on pages 18-21 of Vol. 36, No. 1 of Price-Pottenger Journal. She has a book also, "Sunscreens - Biohazard: Treat as Hazardous Waste", and has been a researcher on it for over 25 years, and is a professor at San Diego University.

She is a professor and research, and has been published. What have you done?
