Skin Changes

Overview

Common skin changes

Most skin changes are normal and occur with aging. Some common skin growths include:

Moles.

Most moles are harmless. They may change over time. They can gradually get bigger, develop a hair, become more raised, get lighter in colour, fade away, or fall off.

Skin tags.

These are harmless growths that appear in the skin folds on the neck, under the arms, under the breasts, or in the groin. They start as small fleshy brown spots and may grow a small stalk.

Seborrheic keratoses.

These skin growths are almost always harmless. They are found most often on the chest or back. Sometimes they're on the scalp, face, or neck. They start as slightly raised tan spots that form a crusty appearance like a wart.

Birthmarks.

Birthmarks are coloured marks on the skin that are there at birth or appear shortly after birth. Most birthmarks are harmless and don't need treatment. Many birthmarks change, grow, shrink, or disappear.

Treatment of a skin change depends on what's causing the skin change and what other symptoms you have. Moles, skin tags, and other growths can be removed if they get irritated, bleed, or bother you.

Causes of skin changes

Causes of skin changes may include:

Hormones.

Acne is a common skin change that occurs during the teen years and may last into adulthood.

Melasma is a skin change in which a person develops patches of skin that are darker than the nearby skin. It can be caused by many things, including hormone changes during pregnancy or menopause.

Sun exposure.

Actinic keratosis and actinic lentigines are types of coloured skin spots that are caused by too much sun exposure.

Medicines.

You may have an allergic reaction to a medicine that causes a skin change. Or you may get a skin reaction when you are out in the sun while you are taking a medicine. (This is called photosensitivity.) Rashes, hives, and itching may occur.

Infections.

Bacterial skin infections, such as impetigo and cellulitis.

Fungal infections, such as ringworm, athlete's foot, and vaginal yeast infections.

Viral infections, such as chickenpox, shingles, and fifth disease.

Diseases.

Autoimmune diseases, such as lupus and scleroderma.

Hepatitis, which may cause your skin and the whites of your eyes to turn yellow (jaundice).

Lyme disease, which causes reactions from a tick bite.

Skin cancer, which may start as a new skin growth, a change in a growth or mole, or a sore that doesn't heal.
