Explained
Polymethylsilsesquioxane is a silicone used as a film forming agent.
When applied to the skin, this ingredient creates an invisible film on the surface. This film still allows oxygen to pass through, but prevents moisture from escaping. This can help condition and hydrate the skin. It also leaves a silky feel when applied.
Polymethylsilsesquioxane has not been shown to clog pores. It has been deemed safe to use up to 55%, but most cosmetics use much less.
If you have concerns about using this ingredient, we recommend speaking with a professional.
