Redness and irritation of the bottom are unfortunately very common. Our Zinc-free Paste (or Protective Balm) is designed to help prevent and soothe inflammation by neutralizing the enzymes which develop when your baby is wearing diapers and which are harmful to their skin's health. Keep changing your baby's diaper as often as possible while making sure to cleanse them well, and gently pat your baby's skin dry before applying the protective base. A visit to the doctor is necessary if the quality of the skin keeps deteriorating despite the hygienic care you provide.
