Dimethicone

Also known as Silicone

A skin-friendly silicone that forms a light, breathable layer on the skin. It smooths, locks in moisture and is the key ingredient in silicone scar gels.

What is dimethicone?

Dimethicone is a silicone, a type of ingredient made from silicon, oxygen and other elements. In skincare it creates a smooth, silky texture and forms a thin, breathable layer on the skin. Silicones have been used in skincare for decades and are considered very safe.

What it does for your skin

  • Helps reduce moisture loss so skin stays hydrated
  • Smooths the look and feel of the skin surface
  • Makes creams glide on easily
  • In scar gels, helps scars look softer, flatter and less red over time

How to use it

For scars, apply a thin layer of our Silicone Scar Gel to clean, fully healed skin twice a day and let it dry. Results build over weeks to months, so consistency is key. In our Redness Relief Moisturizer, Multivitamin Brightening Moisturizer and Retinol 0.5% Night Cream, dimethicone helps seal in hydration.

Who it's for

Dry and sensitive skin, anyone using retinol, and anyone looking to improve the appearance of surgical, injury or acne scars.

Common questions

Does dimethicone clog pores?
No. Dimethicone is non-comedogenic and is used in many products for acne-prone skin.
Is dimethicone bad for your skin?
No. It is one of the best-studied and gentlest skincare ingredients. The layer it forms is breathable.
How long does silicone scar gel take to work?
Most people start to notice a difference after several weeks of twice-daily use, with continued improvement over a few months.
Can I use silicone gel on an open wound?
No. Wait until the skin has fully closed and healed.
