Detailed answer

Body lotions that contain ingredients like alpha hydroxy acids (AHAs), kojic acid, or vitamin C may help fade dark spots on the neck over time. These ingredients work by exfoliating the skin, reducing melanin production, and brightening the complexion. However, it's important to note that the effectiveness of body lotion in treating dark spots depends on factors such as the severity of the spots, individual skin type, and consistency of use. For best results, it's recommended to consult with a skincare professional for personalized advice and consider a comprehensive skincare routine that includes sun protection, proper cleansing, and targeted treatments like serums or spot correctors.
