Polydimethylsiloxane (PDMS)  or commonly known as dimethicone is actually a form of silicone ingredient that is naturally sourced. It is often formulated in a myriad of beauty products including makeup, skincare and even hair care. Additionally, the primary function of this emollient ingredient is to provide a silky and smooth texture that is usually associated with creams, moisturisers, lotions and primers. The ‘slip’ that it imparts allows the product to be spread easily on the skin. 

Benefits of Dimethicone

Although dimethicone has widely received mixed perceptions on its efficacy, this controversial ingredient actually brings several known benefits to the skin. The pros of using beauty products with dimethicone are as below:

  • It adds silky smooth texture to the products
  • Protects the skin by forming a protective barrier
  • Packed with occlusive properties that retain the moisture level
  • Soothes inflammation and redness
  • Features non-comedogenic and non-acnegenic properties that won’t clog the pores
  • Provides matte finish when added into makeup formulation
  • Prevents hair frizziness 
  • Conditions the hair for soft and shine finish 
  • Binds other ingredients from separating

Are There Any Side Effects of Using Dimethicone?

As we have mentioned earlier dimethicone is an occlusive ingredient, hence the question that has been lingering on people’s minds is whether it is actually comedogenic or not. Contrary to the popular belief, it is actually non-comedogenic, so it will not clog any pores or cause acne. In fact, a previous study published in 2014 found that dimethicone is suitable for those who have acne-prone or sensitive skin types as it features non-comedogenic and hypoallergenic properties. You might even be surprised to know that dimethicone is often included as one of the ingredients for oil-free moisturisers. 

In a review by the Cosmetic Ingredient Review Expert Panel, the majority of the beauty products constitute less than 15% of dimethicone. Hence, such a percentage is regarded as a safe amount. Although there’s a concern that people have over dimethicone, the truth is actually far from that as there is no evidence to support such views. However, similar to other ingredients, some people might experience side effects like itching, irritation, swelling and burning sensation. If such a situation ever happens to you, the easiest way to remove dimethicone from the skin is simply by removing the remnants of the product with gentle soap and water.
