Ans. Weight loss can often help improve dark neck discoloration, especially if it is caused by obesity-related factors. Excess weight can lead to skin folds and increased friction in the neck area, contributing to acanthosis nigricans (dark neck). As you lose weight, the friction and pressure decrease and the skin may gradually lighten. However, it's essential to address other potential causes of dark neck, such as hormonal imbalances or genetics, which may require additional treatments. Consulting a dermatologist can provide a more accurate assessment and guidance for your specific situation.
