"Skin problems" is a broad term that is quite subjective. One person's skin problem may be an occasional pimple, while another's skin problem is a severe case of flushing and bumps that defines rosacea. Rashes, acne and discoloration of the skin can all be classified under the wide umbrella of "skin problems." Just as there are many different types of skin problems, the causes of skin abnormalities are numerous, and some are even unknown. Common reasons for skin issues are allergies, hormones and genetic abnormalities involving the immune system.
Allergic Reaction
Skin problems, mainly rashes, may be an allergic reaction to a food, medication or other substance with which your skin comes in contact. Contact dermatitis is a common cause of skin rash and can be provoked by contact with a plant, such as poison ivy, or chemicals that are too harsh for your skin, including laundry detergents and makeup. Eczema, also called atopic dermatitis, is another allergic skin condition. People who suffer from asthma or seasonal allergies are more likely to also develop eczema, according to the National Institutes of Health.
Infection
Viral and bacterial infections can lead to skin problems that include rashes, sores and blisters. Common diseases that affect the skin include chicken pox, shingles, measles, impetigo, roseola and fifth disease. Impetigo is a bacterial illness that can be treated with topical antibiotics. Most childhood diseases that produce a rash or other skin issues tend to be viral and must run their course. Topical ointments can be used to alleviate discomfort associated with skin lesions but will not cure the condition itself.
Immune System Disorders
Skin problems may also be the result of a faulty immune system. Vitiligo is a skin problem in which areas of the skin lose pigment. The exact causes of vilitigo are not known. According to the National Vitiligo Foundation, researchers think that some of the disease may be immunologic in nature, meaning something has gone wrong in the immune system that prompts the skin to lose its color.
Hormonal Changes
Several different types of skin problems can occur during hormonal changes throughout a person's life. Males and females may see skin eruptions (acne) throughout their teenage years. Women who are pregnant may experience a temporary darkening of the pigment on their faces called melasma. Menopausal women often experience severe flushing during hot flashes that are consistent with menopause.
