Boudreaux’s Butt Paste is a powerful and fast acting diaper rash prevention product yet it is free of the harsh butt-irritating ingredients like Parabens, Preservatives, Dyes, Phthalates and Talc ingredients included in some diaper rash ointments. Pediatricians have always recommend parents use a diaper rash cream/ointment that leaves a thick barrier between the diaper and the skin, exactly why Boudreaux’s Butt Paste has been specially formulated to provide the thickest barrier of protection that forms immediately upon contact with your baby’s bottom.
