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.
