What Is Dimethicone?

Dimethicone is a type of silicone-based polymer widely used in skincare and cosmetics. It forms a protective barrier on the skin, locking in moisture and creating a smooth, silky finish.

It’s commonly found in:

• Primers
• Moisturizers
• Foundations
• Serums
• BB/CC creams

According to the Cosmetic Ingredient Review Expert Panel, dimethicone is considered non-comedogenic, hypoallergenic, and safe for use in personal care products—even around the eyes and lips. It forms a breathable, protective film that helps prevent water loss without suffocating the skin.

Benefits of Dimethicone in Skincare

• Creates a Smooth, Velvet-Like Finish
• Seals in Moisture
• Reduces Irritation
• Non-Greasy Feel
• Enhances Product Spreadability

A study published in PMC confirms dimethicone’s role in maintaining skin barrier function and reducing symptoms of dry, itchy, or compromised skin.

But... Is Dimethicone Actually Bad for You?

🔥 Myth: Dimethicone suffocates the skin – False. It forms a semi-occlusive, breathable film.

⚠️ Myth: It causes breakouts – False. Dimethicone is non-comedogenic, but improper product layering or poor cleansing can trap other comedogens underneath.

🧪 Concerns about microbiome interference and long-term barrier disruption exist, but there is no definitive clinical evidence to support them.

When to Avoid Dimethicone

Avoid or limit dimethicone if:

• You live in a hot/humid climate and use multiple occlusives
• You have extremely reactive or allergy-prone skin
• You notice breakouts from silicone-heavy routines

How to Use Dimethicone Safely in Your Routine

• Apply after water-based serums to lock in hydration
• Always double cleanse if using in makeup or long-wear primers
• Avoid layering with other occlusives unless your skin is very dry
• Opt for non-comedogenic and fragrance-free formulas
