Common treatments for noninfectious facial skin rashes include topical steroid creams such as hydrocortisone, oral steroids, oral antihistamines, and moisturizing and medicated lotions, according to MedicineNet. However, facial rashes caused by an underlying infection, such as a fungus, are generally treated with antifungal medication.
Most noninfectious facial rashes are treated according to symptoms or are left alone for a period of time to see if improvement occurs, according to MedicineNet. Topical hydrocortisone cream can help to provide relief from itching and is available over the counter.
Oral antihistamines such as hydroxyzine and diphenhydramine can also be helpful for controlling itching and preventing the body from overreacting to an allergen, according to HealthLine. Severe rashes may require treatment with oral steroids.
Treatment of a facial rash caused from an allergic reaction to a particular drug requires that use of the drug is discontinued, and if needed, a short course of oral steroids is taken. Rashes due to fungal infections are most effectively treated with topical antifungal medications containing ingredients such as clotrimazole, according to MedicineNet.
Calamine lotion is a medicated lotion commonly used for soothing several types of facial rashes caused by contact dermatitis. Additionally, oatmeal bath products are recommended for relief of rashes such as eczema or psoriasis, according to MedlinePlus.
