Diaper Rash: What is the function of Eryplast?

Diaper rash, also known as diaper dermatitis, is a skin inflammation that occurs on the buttocks, groin, and thighs. Diaper rash results from prolonged exposure to moisture, repeated friction, or an infection caused by bacteria or fungus. Diaper rash primarily affects babies and children. Indeed, this inflammation particularly develops in warm and humid environments, such as diapers. Therefore, wearing diapers is a factor in the occurrence of diaper rash. It is mainly characterized by redness, although in some cases, the skin can become more sensitive and cause burning and itching sensations. A diaper rash that is promptly addressed poses no risk. However, without treatment, it can progress to a more severe form, with the emergence of blisters and bleeding.

Most of the time, managing diaper rash involves applying a zinc oxide-based treatment, such as Eryplast.

This molecule operates on multiple levels to soothe the skin and curb diaper rash. Zinc oxide is primarily known for its anti-inflammatory properties and its ability to inhibit the expression of certain pro-inflammatory cytokines responsible for redness and skin irritation. It also promotes skin healing by encouraging collagen synthesis. Another interesting property of zinc oxide: it tightens skin tissues, which limits the absorption of moisture and thus prevents maceration, a factor that can exacerbate the diaper rash.

Finally, zinc oxide is capable of forming a protective barrier on the skin's surface, thereby reducing friction and preventing the occurrence of new lesions. This action of zinc oxide also prevents bacteria, fungi, and other pathogens from colonizing the skin. It thus prevents the risks of secondary infection, a phenomenon that can complicate diaper rash. Glycerin is also found in the formulation of Eryplast, a molecule known for its humectant action, as well as its anti-inflammatory and healing properties.

Did you know? Eryplast is also referred to as "water paste" because it does not contain oil, allowing moisture to evaporate more quickly.

Eryplast is ideally applied after each diaper change and has no specific contraindications, whether it's used on young children or by pregnant women. However, it's important to note that if diaper rash does not improve or worsens after four days of regular Eryplast application, it is recommended to seek a doctor's advice.
