Diagnosis:

Rosacea is diagnosed by a dermatologist through medical history and physical examination.

Oral medications like antibiotics and topical gels like Brimonidine and azelaic acid are used to subside pimples and redness in rosacea. Laser treatment can control telangiectasia and surgery might be needed if nose disfigurement occurs.

Diagnosis:

After history and examination, a doctor will order additional tests if he suspects a malar rash. These include specific antibody tests for lupus such as antinuclear antibody tests and ESR/CRP. Niacin levels might be ordered if pellagra is suspected.

Malar rash is treated according to its cause. If lupus is present, nonsteroidal anti-inflammatory drugs (NSAIDs), antimalarials, steroids, and immunosuppressants would be prescribed. If there is a bacterial infection, antibiotics are given. Sensitive skin is protected via topical sunscreens and lotions.
