Overview

Randomized trial evaluates whitening effects of mineral sunscreens in diverse skin tones, suggesting user preferences impact sun protection efficacy.

Key Points

  • The study aims to assess the whitening effect of mineral sunscreens on different skin tones and how this affects consumer preferences and sunscreen efficacy.
  • Five mineral sunscreens and one chemical sunscreen tested on forearms at 2 mg/cm2.
  • Two sunscreens randomly assigned for application on lower legs; preferred product applied to face.
  • Hybrid Diffuse Reflectance Spectroscopy used to determine UVAPF and SPF.
  • Controlled application caused significant whitening, especially three times more on darker skin tones.
  • Uncontrolled application reduced the amount applied and sunscreen efficacy, along with whitening.
  • Participants preferred sunscreens with less whitening, affecting their choices.
