Detailed answer

To diagnose hyperpigmentation, a skincare professional will visually inspect the affected areas to identify any irregularities in skin pigmentation. Medical history, including questions about any recent changes in skincare routine, exposure to sun or chemicals, and any pre-existing medical conditions, will also be taken into consideration. In some cases, a skin biopsy or special imaging tests may be recommended to confirm the diagnosis and rule out any underlying medical conditions. It is important to consult a skincare professional for an accurate diagnosis and appropriate treatment plan for hyperpigmentation.
