The symptoms of skin allergies can vary in severity and presentation, but commonly include:

1. Itching: Itchy skin is one of the hallmark symptoms of skin allergies. The affected area may feel intensely itchy, leading to scratching, which can worsen the condition.

2. Rash: A rash is a noticeable change in the texture or color of the skin. It can appear as red, swollen, raised bumps (hives) or as a more generalized redness and inflammation.

3. Redness and inflammation: The skin may become red and inflamed around the affected area. This inflammation is caused by the release of chemicals by the immune system in response to the allergen.

4. Dry or scaly skin: Allergic reactions can cause the skin to become dry and scaly. This can lead to flaking, peeling, or the formation of rough patches on the skin.

5. Blisters: In some cases, skin allergies can result in the formation of blisters filled with fluid. These blisters may be itchy or painful and can break open, leading to oozing and crusting.

6. Swelling: Allergic reactions can cause swelling, also known as edema, in the affected area. The swelling may be localized or more widespread, depending on the extent of the allergic reaction.

7. Sensitivity and tenderness: The skin may become sensitive and tender to touch. Even slight pressure or friction on the affected area can cause discomfort.

Skin allergies can be triggered by a wide range of substances, including certain medications, cosmetics, soaps, detergents, fragrances, metals (such as nickel), latex, plants (like poison ivy or poison oak), and certain foods. The specific allergens and the severity of the reaction vary from person to person.

If you suspect you have a skin allergy, it is important to seek medical advice for proper diagnosis and treatment. A healthcare professional can help identify the allergen causing the reaction and recommend appropriate measures to manage and alleviate symptoms, which may include topical corticosteroids, antihistamines, or avoidance of the triggering substance.
