• Babies are born with skin pH close to neutral: 6.6 - 7.5
• Adults have a much more acidic skin with pH values: 4.5 - 6.7
• Acidic skin pH affects several activities:
• Maturation and maintenance of the epidermal permeability barrier
• Control of the desquamation process
• Regulation of bacterial proliferation on the skin
Importance of proper pH
