Babies' skin is thinner and more fragile; that's why it is so important to use products that are especially formulated and proven mild enough for their delicate skin. In adults' toiletries, the surfactant (cleaning effect) is harsher, causing dryness to baby's skin and skin irritation. However, mild surfactant used in baby toiletries cleans without removing natural moisture, maintaining baby's skin hydration and leaves baby's skin soft and smooth after use.
