Skin pigmentation changes

Skin pigmentation changes refer to changes in skin color: the skin may darken (hyperpigmentation) or lighten (hypopigmentation) from its normal tone. Such changes can appear as localized patches or over larger areas of skin. Pigmentation changes can be harmless, such as sun-related age spots, but they may also be linked to skin diseases, inflammation, or, more rarely, more serious illnesses.

In Finland, the most common causes of pigmentation changes are damage caused by UV radiation from the sun, aging, skin rashes, scars, and sometimes hormonal changes (for example during pregnancy). Certain medications, hereditary factors, or repeated skin irritation can also affect pigment production. Changes are more easily seen on fair skin, whereas on darker skin tone changes may be less noticeable.

Pigmentation changes are often harmless, but if rapidly changing, irregular, or dark patches appear on the skin, or if a pigmentation change is associated with other symptoms such as itching, pain, bleeding, or ulcers, it is important to seek a doctor’s assessment. A professional can assess the nature of the change and, if necessary, refer you for further examinations or treatment.
