Rough skin on the chest is primarily caused by allergic dermatitis or seborrheic dermatitis, leading to a localized disruption in skin tissue metabolism. However, other potential causes cannot be ruled out, such as insufficient daily water intake resulting in skin dehydration, or excessive sweat gland secretion interfering with normal skin secretion and metabolism, thereby causing clogged pores.
