Ilex Protectant Paste
You can request free sample sachets before purchase or maybe haggle for a free tube of ilex paste, claiming that a few sachets is not enough to evaluate the product.
In my opinion and based on personal experience, ilex paste is by far the best product to apply to prevent and to heal diaper rash or any other anal irritation, itch or burning sensation.
As a prevention or to treat irritation, only a very small pea size amount of ilex is applied, which can easily be removed using wet wipes after each Bowel Movement, otherwise, using too much ilex can create a sticky gloopy mess between the cheeks.
