Dry skin may still feel rough after moisturizer if the product is too lightweight, applied too late, layered over stripped skin, blocked by dead skin buildup, or used on an irritated skin barrier. Use a gentle cleanser, apply moisturizer to slightly damp skin, switch to a richer cream or ointment, avoid hot water and harsh scrubs, and see a dermatologist if roughness is persistent, painful, cracked, or inflamed.
