Most commercial skin care products contain micronized titanium dioxide coated with alumina, dimethicone, silica, and trimethoxy capryl silane. Hence, it does not penetrate deep into the skin.

Several studies have proven that titanium dioxide, even as nanoparticles, does not penetrate the skin or stratum corneum (SC) (2). A study published in the International Journal Of Environmental Research And Public Health demonstrated that titanium dioxide nanoparticles (TiO2NPs) could not permeate intact and damaged skin (3). It has been suggested that it can exhibit a potentially toxic effect on the skin only after long-term exposure.

It is thought to have carcinogenic properties when taken orally or inhaled. However, none of the studies found any evidence of carcinogenicity of titanium dioxide (4). Also, there is no evidence of adverse effects of titanium dioxide after topical application. However, some people can be allergic to it, and upon topical application, titanium dioxide may:

  •  Irritate your eyes and skin
  •  May cause coughing, phlegm, and shortness of breath (if inhaled).

Titanium dioxide is not a new name in the skin care industry. It has been used in powder-based makeup and sunscreens. However, there have been a few safety concerns about using titanium dioxide for the skin. Though there are a few speculations about the ingredient’s toxicity, there is not enough scientific evidence to prove that titanium dioxide is unsafe for your skin. However, if you are allergic to the topical application of titanium dioxide, it may cause a few reactions. Therefore, if you have been using products with titanium dioxide, you may continue using them; otherwise, do a patch test before using.
