What Causes Skin Sensitivity? (And How to Strengthen a Reactive Skin Barrier)

What causes skin sensitivity?

Skin sensitivity occurs when the skin barrier becomes weakened or compromised. This allows irritants to penetrate more easily, leading to redness, dryness, or discomfort.

Main causes include:

• over-exfoliation
• harsh skincare ingredients
• environmental stress
• lack of hydration
• overuse of active treatments

What is the skin barrier?

The skin barrier protects against environmental damage and prevents moisture loss. When it is damaged, skin becomes reactive and inflamed.

How to strengthen sensitive skin

Focus on:

• barrier-repair skincare
• gentle cleansing
• hydration support
• reducing irritation triggers

Consistency is more important than intensity.

Key takeaway

Sensitive skin is repairable but only through calm, consistent support.
