Your skin is also the part of you everyone sees. Any issue with it naturally may cause you to feel self-conscious and even leery of asking questions. But, know you’re not alone. Skin allergies and rashes are common.2
Also know we’re here for you. You may be tempted to try a DIY treatment. But, this could end up making the condition worse in the long run. The good news is we have a discreet solution you can use to get help.
Let’s talk about some possible symptoms and causes of skin allergies and rashes.

- Rash
Skin allergy causes include:
- Cold or hot temperatures

Rashing out?
Skin rashes vary widely. They may be dry, itchy, scaly or red. They may also appear as blotches, blisters or welts.4
Common rashes include:
Eczema.5 This is also sometimes called atopic dermatitis, which is the most common type of eczema. Skin with eczema can be dry, red, irritated and itchy. Sometimes eczema causes small bumps filled with fluid. The fluid may be clear or yellow. People with eczema often have a history of allergies in their family.
Hives. Hives are red bumps or welts. There are two types of hives: acute urticaria and chronic urticaria. Hives that last less than six weeks are acute urticaria. This type is most often caused by allergy or infection. Hives that last over six weeks are chronic urticaria. The cause is largely unknown.
Contact dermatitis. Contact dermatitis occurs when skin contacts an allergen or irritant, including:
- Soaps
- Shampoos
- Laundry detergents and fabric softeners
- Metals like nickel
- Nail polish
- Topical lotions, creams or medications
- Adhesives
- Latex or elastic gloves
- Plants
Photoallergic contact dermatitis is another type of rash. It’s caused by sunlight shining on:
- Sunscreen
- Some perfumes
- Shaving lotion6
Some rashes are more serious than others. Find out when to get emergency care.
