How Skin-Friendly pH Works

The skin barrier thrives in a slightly acidic environment. Products with skin-friendly pH use buffers to stay near this range instead of drifting alkaline. This reduces irritation in wipes, pads and diaper topsheets, particularly for babies and sensitive users. It is a core claim in gentle-care marketing.

Examples and Applications

  • Skin-friendly pH wipes are recommended for daily baby care
  • Feminine hygiene wipes use pH-balancing for comfort
