Chemical sunscreens have ingredients (oxybenzone, avobenzone, octisalate, octocrylene, homosalate, and octinoxate) that may potentially cause health problems. According to some recent researches they seep through the skin into the bloodstream after only a couple hours. These chemicals persist in the blood for up to seven days and exceed, by up to 40 times, the allowed limits.
