In most cases, rash spots on the face are harmless and resolve themselves over time. Persistent rash spots on the face may be a sign of an underlying condition, according to Medline Plus, a National Institutes of Health website. If you develop a rash on your face after taking medication or eating certain foods, seek immediate medical attention, because this can be a sign of a potentially serious allergic reaction.
Rosacea
Rosacea creates a red, inflamed appearance on the skin. You may also notice pus-filled bumps similar to acne. People with rosacea often experience cycles of having little to no symptoms, then flare-ups where the condition may cover most of the face. There is no cure for rosacea, but topical and oral antibiotics can help reduce the symptoms, explains the Mayo Clinic. You may find that you can treat your rosacea successfully at home with over-the-counter products. Talk to your dermatologist if your symptoms do not improve with self-care.
Allergic Reactions
Allergic reactions can lead to rash spots on your face, particularly if you have a drug or food allergy. Rashes caused by allergies may appear on other parts of your body as well, or they may stay localized to your face. A rash brought on by an allergic reaction often appears suddenly and may cause itching or pain. Discontinue use of any substance you suspect is irritating your skin and see a doctor if you suspect an allergy, especially if you experience other symptoms, such as nausea, vomiting or difficulty breathing.
Contact Dermatitis
Contact dermatitis is a condition that causes redness and swelling of the skin. Contact dermatitis can appear anywhere on the body, but you may notice a rash on your face if your skin comes into contact with clothing dyes, cosmetics or some soaps. Chemicals in elastic, latex and rubber products can also lead to a facial rash, according to Medline Plus. Some plants, such as poison ivy and poison oak, can leave an itchy, discolored rash if they rub against your face. Rashes from contact dermatitis usually clear up on their own, but you can use a cool compress or topical creams containing hydrocortisone to alleviate swelling, itching and burning.
Ringworm
Ringworm is a fungal infection that is most common in children. The condition gets its name from the red, ringlike appearance of the rash. Rashes from ringworm most often appear on the face and scalp and usually itch. Antifungal creams can help clear the infection and eliminate the rash. Ringworm rashes may take several weeks or even months to go away completely, according to the website FamilyDoctor.
Shingles
Shingles is a condition that leads to a painful, blistering rash that often spreads over multiple areas of the body and may include the face. Most people that get shingles are over the age of 50 or have a weak immune system from another disease or condition, according to FamilyDoctor. Shingles pain often begins a few days before the rash appears, and you may experience other symptoms including fever, nausea, diarrhea and difficulty urinating.
Antiviral medications can help clear up shingles rashes and over-the-counter pain relievers and anti-itch lotions can help minimize symptoms during the healing process. It is important to see your doctor if you suspect your facial rash is shingles because the condition can infect your eyes, which may damage your vision or lead to glaucoma later in life.
