It is incredibly soft and kissable, and it is also your baby's main source of protection from the outside world. Your baby's skin is thinner and less oily than an adult's, making it more prone to damage and less resistant to harm. It also produces less melanin, the substance that helps ward off sunburn. Every product you use to care for your baby's skin will be absorbed directly into her delicate body, so make sure that it is mild, healthy, and pure.
