There are many Diaper Rash creams and ointments available on the market so what makes Diaprex different and why should you choose it over the other brands?

A time-tested (over 50 years), hypoallergenic formula.

Diaprex helps create a potent barrier to all types of moisture on the skin. Some of the other products contain emulsions that can be less efficient barriers to moisture.

Diaprex features a simple, elegant, and effective combination of ingredients designed to prevent skin irritation and infections from developing while maintaining healthy skin in the toughest of environments, your Baby’s bottom.

Generations of Moms and Dads were Diaprex babies and they have passed the tradition onto their children and grandchildren. Diaprex has a long legacy of proven effectiveness and safety.

        Diaprex Diaper Rash Ointment – What is it?

        Diaprex Diaper Rash Ointment is an elegant hypoallergenic formulation used as a moisturizer to treat or prevent dry, rough, scaly, itchy skin and minor skin irritations (e.g., diaper rash, heat rash, chafing, and skin burns from radiation therapy).

        Diaprex incorporates two active ingredients; zinc oxide 9.6% and white petrolatum 67.6% that together act to create a potent barrier between your Baby’s skin and the moisture, urine, and stool found in the diaper area. Healthy skin barrier function is essential for the prevention and treatment of diaper rash.

        To be healthy, skin also needs the proper amount of hydration. Dry skin is caused by a loss of hydration (water) in the upper layers of the skin. To maintain hydration, Diaprex incorporates a complex of 3 natural emollients (lanolin USP, beeswax, and castor oil) we call Sūthe. Emollients are substances that soften and moisturize the skin while decrease itching and flaking. Sūthe helps your baby’s skin achieve and maintain healthy hydration levels.

        The last ingredient, Balsam Peru, a natural fragrance, gives Diaprex a pleasant smell.

        What is Diaper Rash?

        Diaper rash is any rash that forms in the diaper area including the buttocks, thighs, and genitals. In mild cases, the skin may be red. In more severe cases, there may be painful, open sores. Mild cases clear up within 3 to 4 days with treatment. More than half of babies between 4 and 15 months of age have diaper rash at least once in a two-month period.

        What causes Diaper Rash?

        Consider what a diaper does and where it is used. The “Diaper Area” is warm with a steady supply of moisture in the form of sweat and urine. When skin stays wet too long, it starts to break down. In addition, stools are composed mostly of microorganisms that really like this type of environment so the Diaper Area is a perfect breeding ground for things that can cause skin irritation and dermatitis. These microorganisms also produce enzymes that can irritate, break down, and disrupt the natural skin barrier function.

        Diapers can also cause chafing or rubbing that can physically disrupt the skin’s natural barrier function causing further irritation and allowing microorganisms to enter the skin leading to infection. Some babies develop allergies to the diaper material itself.

        Changes in food (liquid-to-solid, breast milk-to-formula) can sometimes cause babies to experience diarrhea which leads to more frequent, watery stools, further increasing the likelihood of skin irritation. Antibiotics given to the baby or breast-feeding moms can shift the natural balance between the microorganisms in your baby’s intestinal tract leading to diarrhea.

        What are symptoms of diaper rash?

        Look for any changes in your baby's disposition. You may notice your baby seems more uncomfortable than usual, especially during diaper changes. A baby with a diaper rash often fusses or cries when the diaper area is washed or touched.

        Diaper rash can appear suddenly and it affects the areas of the body that are in contact with the diaper: the buttock, thighs, and genitalia. Diaper rash can present in a number of ways: 

        The skin will appear pink to red over a small or large area corresponding to where the baby’s skin has been in contact with the diaper.
        You may see flaking, dryness, or peeling of the skin.
        Look for chafing around the buttock and thighs due to friction
        of the diaper rubbing against the skin.
        The affected areas may be very sensitive and warm to the touch.
        There may be dry raised bumps called papules or fluid containing raised bumps called pustules. These may be a sign of a serious infection that requires the immediate attention of a physician.
        The affected areas may be swollen. The medical term for this is called edema.

          How do you treat Diaper Rash?

          If your baby has a diaper rash, it is important to keep the area as clean and dry as possible. Change wet or soiled diapers right away. This helps reduce how much and how long moisture is in contact with your baby’s skin.

          Gently clean the diaper area with water and a soft washcloth. Disposable diaper wipes may also be used. Avoid wipes that contain alcohol and fragrance. It is very important to remember to minimize rubbing when cleaning as it can further abrade the skin making the rash worse.

          There are cleansing soaps available, specially formulated to help clean off stool that is difficult to remove with regular soap or even diaper wipes. They are great because they help remove dried or chalky stool from the skin and out of deep folds with minimal rubbing. The foam type soaps are also nice because they stick to the diaper area when applied and therefore do not drip or run onto the changing area.  

          Always pat or air dry fully; do not rub. Apply a thick layer of Diaprex Diaper Rash Ointment to the entire diaper area. In this case, more is better because Diaprex is very hydrophobic meaning it repels water and moisture. It forms a protective barrier so liquids like sweat, urine, and watery stools cannot penetrate the skin. It also helps prevent the naturally occurring enzymes in stool from affecting the diaper area and it acts like a lubricant to reduce rubbing and chafing the skin.

          When closing the new diaper, do not make it too tight, especially overnight. A tight diaper can contribute to the problem by rubbing against the skin and causing more irritation.

          How can Diaper Rash be prevented?

          Expose your baby's bottom to fresh air by
          leaving the diaper off whenever possible.
          Be aware and change your baby’s diapers as soon as they are wet or soiled. Clean, dry diapers reduce the risk of diaper rash.
          Use mild detergent to wash your baby’s clothes and linens.
          Carefully observe any changes in your baby’s skin and
          digestion when introducing new foods.

            Which type of diaper is best for my baby?

            Diapers are made of either cloth or disposable materials. Cloth diapers can be washed after they get soiled and used again. Disposable diapers are thrown away after each use. Research suggests that diaper rash is less common with the use of disposable diapers. However, what is more important than the type of diaper is how often it is changed.

            Whether you use cloth diapers, disposables, or both, always change diapers as needed to keep your baby clean, dry, and healthy.

            When should I call the doctor?

            Sometimes a diaper rash needs medical attention. Contact your baby’s doctor if yu observe any of the following:

            The rash does not look like it's going away or
            gets worse 2 to 3 days after starting treatment
            The rash includes blisters or pus-filled sores
            Your baby is taking an antibiotic and has a bright
            red rash with red spots at its edges
            Your baby has a fever along with a rash
            The rash is very painful
            You suspect a yeast infection
