Diagnosis
Hyperpigmentation is usually diagnosed through a clinical skin examination by a dermatologist. In some cases, a Wood’s lamp examination or dermoscopy may be used to determine the depth and cause of pigmentation.
Prevention
* Apply a broad-spectrum sunscreen (SPF 30 or higher) every day.
* Limit excessive sun exposure.
* Avoid picking or squeezing acne and skin lesions.
* Follow a gentle skincare routine.
* Seek early treatment for inflammatory skin conditions.
When to See a Dermatologist
Consult a dermatologist if dark patches appear suddenly, continue to spread, change in appearance, or do not improve over time. A professional evaluation can help identify the underlying cause and recommend the most appropriate treatment.
Note: Hyperpigmentation is a common and treatable condition. Early diagnosis and consistent sun protection can help improve skin tone and prevent further pigmentation.
