An adult’s skin is usually exposed to multiple things like harsh climate, environmental changes, chemicals, etc. that tend to have an unwanted impact on it. On the other hand, a baby's skin is delicate, tender and sensitive. The skin of an infant is still developing. The epidermis of a baby's skin is one third the thickness of an adult skin. Hence, dirt and bacteria can easily penetrate through the immature barrier of a baby's skin.
The sweat glands of an infant are less effective, which means that the baby's skin absorbs and loses moisture easily. Due to this the function of temperature regulation of a baby's body is much lesser as compared to that of an adult. Sebum and Melanin are also produced less in a baby's skin. All this means that the baby’s skin calls for more attention and care.
