Dimethicone Benefits & Uses for Skin & Hair
Quick Facts
- Botanical Name: N/A (synthetic silicone polymer)
- INCI Name: Dimethicone
- Extract Type: Synthetic polymer (Polydimethylsiloxane)
- Benefits: Moisture barrier, silky skin feel, frizz reduction, enhanced product spreadability
- Best Uses: Moisturizers, primers, sunscreens, hair conditioners, anti-aging creams
Dimethicone, also known as Polydimethylsiloxane (PDMS), is a synthetic silicone oil valued in skincare and hair care for its ability to create a breathable barrier, lock in moisture, and provide a silky, non-greasy finish. Chemically inert and stable across extreme temperatures, it has been a trusted cosmetic ingredient for over 60 years.
What the Science Says
- Forms a semi-permeable barrier that reduces transepidermal water loss (TEWL) by up to 50% without blocking skin respiration[2].
- Remains on the skin surface due to large molecular size, preventing pore blockage and systemic absorption[1].
- Improves hair smoothness, combability, and shine while reducing breakage by up to 85%[3].
- Demonstrates excellent safety profile with no irritation, sensitization, or comedogenic effects[1][4].
Key Nutrients / Compounds
- Silicon-Oxygen Backbone: Provides stability and durability in cosmetic formulations.
- Methyl Side Groups: Create a hydrophobic surface for water resistance and smooth feel.

FAQs
Is dimethicone safe for acne-prone skin?
Yes. Dimethicone is non-comedogenic and does not clog pores, making it suitable for acne-prone skin.
Does dimethicone block skin from breathing?
No. Dimethicone forms a breathable barrier that reduces water loss while allowing normal skin respiration.
Is dimethicone safe for long-term use?
Yes. It has over 60 years of safe cosmetic use with no evidence of irritation, sensitization, or harmful buildup.
Can dimethicone protect hair from heat damage?
Yes. It coats hair strands, reducing moisture loss and protecting against heat styling damage.
Does dimethicone wash out of hair?
Yes. It is easily removed with regular shampoo and does not cause buildup when used in balanced formulations.
