Diaper rash and skin health

Proponents of cloth and disposable Baby Pant Diapers both claim that babies wearing their chosen type suffer less diaper rash. After talking to two pediatric dermatologists and reviewing the scientific literature on the topic, it is clear to us that disposable diapers do have the edge in preventing the most common type of diaper rash, irritant diaper dermatitis, which is caused by moisture from urine and feces remaining trapped against the skin. Modern disposables are highly absorbent, and, as we found in testing for our guide, the top performers can keep a baby’s skin dry even after multiple wettings. Dr. Bruce Brod, a pediatric dermatologist who specializes in dermatitis, told us: “The skin is largely better off with disposable diapers because of the technology that evolved”—namely, the use of superabsorbent polymers, which take in and retain many times their weight in liquid. But some babies can develop allergic rashes from certain ingredients used in disposable diapers, including rubber, adhesives, fragrances, and dyes.

The conclusion? Either type of diaper can lead to rashes, but disposable diapers typically keep babies drier and better prevent the common problem of diaper rash caused by moisture.
