Dimethicone is a silicone-based polymer and popular ingredient in skincare and personal-care products. The US Food and Drug Administration has approved dimethicone as safe for this use.

Main Ingredient

Dimethicone is the most common ingredient in many skin creams and lotions, shampoos and soaps. Many Aveeno moisturising products contain dimethicone, as does Johnson's Baby Lotion.


Products containing dimethicone are applied externally in cream or lotion form, or used as a shampoo or soap.

How It Works

Dimethicone forms a protective barrier on the skin to help retain moisture. Dimethicone's oil-like consistency also gives it emollient properties.

Side Effects

Dimethicone may cause itching, stinging or burning of the skin in some people. More severe side effects such as hives, difficulty breathing and swelling are rare and caused by an allergic reaction.


If you are using a prescription-strength dimethicone product and become pregnant or are considering becoming pregnant, speak to your doctor about the continued use of dimethicone.
