      Chemical ingredients — such as avobenzone, oxybenzone and homosalate — absorb the UV rays. Both types of sunscreen can degrade or wash off over time, so it’s important to reapply every two hours, and more frequently if you’re swimming or sweating.
    • 2024 June 21, Danielle Sinay, quoting Madhu Shetti, “Is Sunscreen Bad for You? TikTok’s Anti-SPF Movement, Explained”, in Glamour‎[2]:
      As documented in a recent FDA study, chemical sunscreens, with active ingredients like oxybenzone, octocrylene, octinoxate, homosalate, and avobenzone, are applied to the skin and then can remain in the blood plasma at significant levels for days to weeks after application[.]
