my baby neck becoming day by day black and why can you tell me whitening soap

A. this may be due to acanthosis nigricans. acanthosis nigricans is a skin condition that causes thicker and darker patches in skin creases and folds, such as the neck, armpits, or groin. it's often seen in kids who are overweight or obese and may be linked to insulin resistance. although it usually doesn't require treatment, addressing the underlying cause (like weight loss) can help fade these patches. if you suspect your child has acanthosis nigricans, consult a doctor for proper evaluation. remember to gently clean the affected skin and avoid harsh treatments. x encourage a healthy diet and regular physical activity to improve skin appearance. x
