Titanium Dioxide Ewg-Does Titanium Dioxide Block Pores

Titanium dioxide is a common ingredient in sunscreen and other skincare products, primarily used for its ability to reflect and scatter UV rays, providing protection against sun damage. It is considered a physical sunscreen ingredient, as opposed to chemical sunscreens that absorb UV rays.

Titanium dioxide particles are typically very small, often in the nano-size range, but they do not block pores in the way that larger particles, like those found in some makeup or skincare products, might. Instead, they sit on top of the skin’s surface and reflect UV light away. Because of their small size and the way they are formulated in products, they are generally designed to minimize the risk of clogging pores.

However, individual experiences may vary. Some people with very sensitive or acne-prone skin might find that certain formulations containing titanium dioxide can lead to irritation or clogged pores, especially if the product is not well-suited to their skin type or if it contains other comedogenic ingredients.

It’s also worth noting that the risk of pore blockage is more related to the overall formulation of the product rather than the titanium dioxide itself. Non-comedogenic sunscreens are formulated to avoid clogging pores and are often a better choice for those concerned about this issue. If you’re worried about pore blockage or breakouts, look for products labeled as non-comedogenic and consider patch testing new products before applying them to your entire face.
