If you have developed inflammation or a skin rash after you touched or ate something, the chances are that you are allergic to whatever you ate or touched. This article discusses natural alternatives that can help combat skin allergy and soothe the rash. Scroll down for more information.

Types Of Skin Rashes

  • Seborrheic dermatitis: This type of skin allergy results in red, scaly, and itchy lesions that mostly affect the scalp, forehead, brows, cheeks, and external ears.
  • Contact dermatitis: A skin allergy brought about by contact with certain chemicals that an individual may be allergic to. The wrist due to a watch, or the finger due to a ring might be affected.
  • Diaper rash: A type of irritant contact dermatitis that mostly affects infants and some adults who wear diapers soiled with feces and urine for too long. Fungal infection or yeast can also cause diaper rash.
  • Stasis dermatitis: An oozy skin allergy that occurs on the lower legs of individuals who have chronic swelling due to poor blood circulation and/or poor lymphatic drainage.
  • Nummular eczema: An oozy skin allergy that surfaces as coin-shaped plaques on extremely dry skin during the winter.
  • Drug eruptions: Certain antibiotics and pain relievers could produce allergic skin reactions as a side effect.

Skin allergies might also be a result of various underlying causes. However, the end result is mostly the same – swelling and itchy rashes on your skin. The home remedies discussed in this article can help you find relief. Make sure you consult your doctor before opting for any method to avoid complications.

Expert’s Answers For Readers’ Questions

What happens to your body when you have a food allergy?

When you have a food allergy, your immune system reacts by producing antibodies called immunoglobulin E (IgE). They travel to your cells and initiate a cascade of chemicals, causing an allergic reaction. This release causes symptoms in the nose, lungs, sinuses, throat, ears, and skin. There are also IgG delayed food allergy symptoms.

How long does it take for an allergic reaction to go away?

For most allergic reactions, the symptoms begin to fade away within a few hours after the allergen has been removed. They usually clear completely in about two days.

Which medicine works best for skin allergies?

Your doctor might prescribe antihistamines or topical creams containing hydrocortisone to treat skin allergies. However, antihistamines can cause drowsiness, and long-term use of hydrocortisone causes thinning skin.

Which is the best cream for a skin allergy?

You can use anti-itch creams containing hydrocortisone or safer applications like calamine lotion. If you are looking for natural alternatives, any of the above remedies will do the trick.

Which soap works best for a skin allergy?

Soaps containing oatmeal, like Aveeno, or olive oil are great for those with skin allergy. Cetaphil soap is another good option.
