What is Dimethicone and is it safe?
Dimethicone is a type of silicone which is commonly used in cosmetics, hair care and skincare products. It helps products glide over the skin and helps keep the ingredients mixed together. This produces a silky-smooth texture. It also helps fill in pores and fine lines while creating a matte finish on the skin. This can be useful in camouflaging breakouts and redness. Dimethicone is often used as an ingredient in moisturizers to prevent or to treat dry skin and minor skin irritations.
There is some speculation as to whether or not dimethicone causes acne in those with acne-prone skin. However, the evidence to support this claim is mostly anecdotal and is not supported by studies. Human and animal clinical trials of dimethicone indicate that it did not cause irritation when applied to the skin. While this is not the same as acne, it is worth noting that dimethicone is non-comedogenic and forms a vapour permeable barrier on the skin. This means that it is not totally occlusive.
It is possible to have an allergy to Dimethicone. If you experience redness or swelling when using products that contain this ingredient, you should discontinue use and speak to your dermatologist.
