Plant Oils for Barrier Support: Choosing the Right One

Plant oils rich in essential fatty acids have 85-90% dermatologist support for improving dryness, elasticity, and barrier function.

Why Plant Oils Matter

Your skin barrier requires a balanced mix of lipids—ceramides, cholesterol, and fatty acids. Certain plant oils can supplement these lipids, especially for dry or compromised skin.

Top Barrier-Supporting Oils

Understanding Fatty Acids

Linoleic Acid (Omega-6)

Deficiency linked to acne, impaired barrier

Found in: Rosehip, hemp, grapeseed oils

Benefit: Lightweight, non-comedogenic

Oleic Acid (Omega-9)

Better for: Dry, mature skin

Caution for: Acne-prone skin (can be comedogenic)

Found in: Olive, avocado, sweet almond oils

GLA (Gamma-Linolenic Acid)

Anti-inflammatory properties

Best for: Eczema, dermatitis

Found in: Borage, evening primrose oils

How to Choose the Right Oil

For Acne-Prone Skin

Choose high-linoleic, low-oleic oils:

Rosehip seed oil

Hemp seed oil

Grapeseed oil

For Dry/Mature Skin

Choose richer, oleic-acid oils:

Argan oil

Marula oil

Avocado oil

For Sensitive/Eczema-Prone Skin

Choose GLA-rich oils:

Borage seed oil

Evening primrose oil

How to Use Plant Oils

Apply as final step - seal in other products

Use 2-4 drops - a little goes a long way

Can mix with moisturizer if texture is too heavy

Patch test first - especially if you have allergies

Cautions

Patch test - plant allergies are possible

Watch for breakouts - some oils are comedogenic for certain skin types

Storage matters - keep oils away from heat and light

Check expiration - oils can go rancid

The Bottom Line

Plant oils are valuable tools for barrier support, but choosing the right one matters. Match the oil's fatty acid profile to your skin type for best results.
