What Is a Skin Allergy?

A skin allergy happens when the immune system reacts to a substance that normally should not harm the body. These substances are called allergens.

When the skin comes in contact with an allergen, the body releases chemicals like histamine, causing:

• Itching
• Redness
• Swelling
• Rashes
• Burning sensation

Skin allergies can happen to anyone — children, adults, and elderly people.

Common Skin Allergy Symptoms

Here are the most common symptoms of skin allergies:

1. Itching (Pruritus)

Persistent itching is often the first sign of a skin allergy. It may worsen at night or after exposure to heat, sweat, soaps, or cosmetics.

2. Red Rashes

Red patches or rashes can appear on the face, neck, hands, legs, or body.

3. Swelling

Some people develop swollen skin, lips, eyelids, or face after allergic reactions.

4. Dry and Flaky Skin

Allergic skin may become extremely dry, cracked, or rough.

5. Burning Sensation

The affected area may feel irritated or painful.

6. Small Bumps or Hives

Raised itchy bumps are commonly seen in urticaria (hives).

7. Skin Peeling

Severe allergies may cause peeling or blistering.

8. Dark Patches After Allergy

Many patients develop post-inflammatory pigmentation after scratching.

9. Sensitive Skin Reaction

Some people experience immediate reactions after using skincare products or makeup.
