# Irritant Contact Dermatitis

## Quick Summary

Irritant Contact Dermatitis describes a reaction pattern that can look like burning, itching, redness, rash, peeling, swelling, or discomfort after skincare exposure. It is not something to push through when symptoms are persistent or worsening.

## What It Is

This side-effect page is a cautious skincare-education page, not a diagnosis. The same symptoms can come from irritant exposure, allergy, occlusive layering over fragranced products, underlying dermatitis, or unrelated skin disease.

## Causes

Common contributors include fragrance, essential oils, alcohol-heavy formulas, retinoids and acids trapped under an occlusive layer, over-washing, and barrier damage. Timing, location, repeat exposure, and whether symptoms improve after stopping a product all matter.

## Seriousness

Mild, short-lived stinging can happen with some actives, but rash, swelling, blistering, oozing, crusting, eye symptoms, lip swelling, or worsening pain should be treated as more serious.

## When to Seek Care

Stop the suspect product and seek medical guidance for spreading rash, swelling, blistering, or eye-area involvement. Persistent reactions that do not improve after simplifying the routine belong with a clinician.
