Rashes and blotches around the nose can result from an allergic reaction or a harmless skin disease. Babies sometimes develop nose blotches within their first days. Although the causes of many skin blotches are easily identifiable, others require blood tests and biopsies for diagnosis.
Skin blotches around the nose usually are red and rough. They often have small bumps on them that may be filled with pus, as in the case of acne whiteheads. Erythema toxicum is a harmless, red, blotchy rash common in infants; it is usually red with white or yellow bumps in the center of the blotch. Milia is another common skin condition in newborns and appears as yellow or white bumps around the nose. Small red or brown blotches that grow, change shape and eventually crust over and bleed might indicate more serious skin conditions.
Contact dermatitis sometimes causes a red, blotchy rash if your nose comes into contact with an allergen such as poison ivy, latex, dyes or chemicals in skin care products. Seborrheic dermatitis, a genetic skin disease caused by excessive oil production and yeast, produces red blotches that might be aggravated in response to stress, fatigue, oily skin and extreme weather. Eczema is another genetic condition that can produce nose blotches. This condition usually begins in childhood, but children often outgrow the hypersensitivity reaction by early adulthood. Acne, caused by blocked pores, also can leave lesions around the nose. Aging skin contributes to a number of skin disorders, and so seniors might be affected by blotchy discolorations and dry patches around the nose.
Do not squeeze or scratch lesions, rashes and pimples around the nose because they can become infected easily, which might lead to permanent scarring.
Most skin blotches respond well to home care, according to Medline Plus. Gentle soaps and cleansers applied without scrubbing allow the skin to heal naturally. Warm water will not irritate the skin as much as hot water, and pat your nose dry instead of rubbing it after washing to avoid further irritation. Keep the blotch exposed to air while it heals, and avoid heavy cosmetics. Hydrocortisone cream, available over the counter, can relieve itching while the blotch dissipates. Moisturizers that contain petrolatum are especially effective for treating dry skin in seniors. If the blotch does not heal or if it worsens, see your doctor for further treatment options.
Basil cell carcinoma is the most common form of skin cancer and might begin as a blotch on the nose because this area receives constant exposure to the sun. Fair-skinned people with red or blond hair and blue eyes are more prone to this deadly cancer. The blotches eventually bleed and crust over and will spread to other parts of the body if not treated. Early detection of basil cell carcinoma provides a 95 percent chance of being cured, according to the College of American Pathologists.
