Titanium dioxide is a mineral, or physical, sunscreen filter. Rather than absorbing light chemically, it sits on the skin surface and scatters and reflects it. Because it is not absorbed, it is the filter usually recommended for sensitive skin and for children.

What Titanium Dioxide Is Used For

  • Broad sun protection in mineral sunscreens
  • Sunscreens for babies, children and sensitive or reactive skin
  • Products for skin prone to pigmentation and melasma
  • A white pigment in creams, makeup and toothpaste

Common Side Effects

  • A white cast on the skin, more visible on darker skin tones
  • A heavier feel than chemical sunscreens
  • Occasional blocked pores in oily skin

Precautions

Mineral sunscreen works immediately on application, but it rubs and sweats off, so reapplication every two to three hours outdoors still matters. Tinted versions reduce the white cast considerably. Avoid loose powder or spray forms around the face of a small child, since inhaling the fine particles is best avoided.
