Skin allergies are a widespread issue affecting people of all ages. They can range from mild irritations to severe allergic reactions, causing discomfort and impacting daily life. Understanding the causes, symptoms, and management of skin allergies can help prevent flare-ups and improve skin health.
In this blog, we will discuss the common causes of skin allergies, how to identify them, and the best ways to manage and prevent them.
What Are Skin Allergies?
A skin allergy occurs when the immune system reacts to an allergen (a substance that triggers an allergic reaction). This reaction leads to redness, itching, swelling, or rashes on the skin.
Skin allergies can be caused by a variety of triggers, including food, chemicals, plants, weather conditions, and even stress. Some reactions happen immediately, while others develop over time.

✔️ Jewelry (especially nickel)
✔️ Latex (gloves, balloons)
✔️ Certain plants (poison ivy, sumac)
🔹 Symptoms:
🔹 Itchy red rash
🔹 Dry, cracked skin
🔹 Blisters or swelling
💡 How to Manage:
