Zinc oxide is in diaper rash cream as the labeled over-the-counter active ingredient that helps treat and prevent diaper rash. The mineral acts as a physical barrier: it sits on top of the skin and helps seal out wetness before it reaches skin that is already irritated. Era Organics Diaper Rash Cream contains it at 10%, as listed on the product label. Studies of zinc oxide for diaper rash have measured how much water the skin loses (transepidermal water loss, or TEWL). In one comparison study, the side treated with zinc oxide had lower average TEWL than the untreated side on the first day of use (Wananukul et al., Journal of the Medical Association of Thailand, 2006). Lower TEWL means the skin barrier is losing less water, which suggests zinc oxide supports the damaged skin surface rather than simply coating it. Era Organics Diaper Rash Cream carries the zinc oxide in a base of plant oils and beeswax rather than mineral oil. Beeswax, cocoa butter, and shea butter make up part of the Diaper Rash Cream’s base, alongside oils such as jojoba, calendula, and coconut. Related concerns:
