For adults, phenyl trimethicone is generally safe when applied to the skin. It’s a silicone that makes skin and hair feel smooth. Major reviews find low risk for cancer, allergies, and effects on pregnancy. A small number of studies show it can cause mild irritation to skin, eyes, or breathing in some people.
If you plan to use a product that lists phenyl trimethicone: do a small patch test on your inner forearm first; avoid spraying it into the face to prevent breathing it in; keep it out of your eyes; follow the product label and do not use on broken skin; stop use and rinse if you get irritation. If you are pregnant, breastfeeding, or have serious skin conditions, talk to your healthcare provider if you have concerns.
