Pampers Fresh Clean wet wipes provide even more thorough cleaning (compared to the previous product) thanks to the softer and stronger wet wipe, but still with the refreshing scent that you and your baby love. Enzymes from urine and bowel movements alter the pH of baby's delicate skin, increasing the risk of irritation and diaper rash. All Pampers wet wipes contain a unique formula that protects the natural pH of baby's skin better than cotton and water. Pampers Fresh Clean wet wipes are dermatologically tested and endorsed by dermatologists from the Skin Health Alliance. Because Pampers Fresh Clean wet wipes are designed for baby's sensitive skin, they do not contain alcohol, dyes.
