Dark patches on the neck can be caused by various factors including sun exposure, hormonal changes, or skin conditions like melasma or post-inflammatory hyperpigmentation. These patches often appear as uneven, darker skin areas and can be exacerbated by frequent friction or irritation. Other possible causes include certain medications or underlying health conditions. To address dark patches, it's essential to use sun protection, maintain a consistent skincare routine, and consult a dermatologist for targeted treatments. Professional treatments such as chemical peels, laser therapy, or topical medications may be recommended based on the severity and underlying cause of the pigmentation.
