1. Zinc Oxide
2. Titanium Dioxide

To understand why these ingredients contribute to a white cast, we can explore each one in detail.

  1. Zinc Oxide:
    Zinc oxide is a mineral compound used in many sunscreens for its effective UV protection. Zinc oxide reflects and scatters UV rays. When applied to the skin, it is often visible, especially on darker skin tones. A study by the Skin Cancer Foundation (2021) highlights that products containing high concentrations of zinc oxide are more likely to leave a noticeable white cast. Despite this drawback, zinc oxide is favored for its broad-spectrum protection and skin-soothing properties.

  2. Titanium Dioxide:
    Titanium dioxide is another mineral sunscreen ingredient that provides UV protection by scattering UV radiation. Like zinc oxide, it can create a white cast, particularly when used in larger particle sizes. A research paper [Journal of Cosmetic Dermatology, 2020] notes that titanium dioxide is often formulated into nanoparticle size to reduce visibility; however, some formulations still appear opaque on the skin. There is ongoing debate regarding the safety and efficacy of nanoparticles, but many consumers appreciate titanium dioxide for its hypoallergenic attributes.

The contrasting benefits and drawbacks of these ingredients highlight the importance of formulation in minimizing the white cast while providing effective sun protection.
