Researchers emphasize the findings don't mean people should refrain from using sunscreen, which can help to prevent skin cancer and protect the skin.

‘The randomized trial assessed the absorption of six active ingredients (avobenzone, oxybenzone, octocrylene, homosalate, octisalate and octinoxate) in four sunscreen products formulated as lotion and sprays (aerosol, nonaerosol and pump).’

More research is needed to determine the effect of exposure to sunscreen ingredients. This study was conducted indoors in a clinical research setting and participants weren't exposed to direct sunlight during the seven days they remained at the clinic. 




A change in study design from an indoor to an outdoor setting would better represent real-life sunscreen application. The study also wasn't designed to assess the absorption difference by formulation or skin types.
