A child’s skin has a very similar structure and functions to the skin of an adult, but:

Some functions are not mature. The pH level of a child’s skin is higher and its protective function is less developed,

The child’s surface-to-weight ratio is almost three times higher than the adult’s: the risk of toxicity is therefore higher because the penetration is three times higher,

certain functional anatomical characteristics are different: hyper-plasticity of the skin with a rich vascular dermal network, a thinner horny layer of the epidermis, and melanocytes that are less functional during the first year.

Therefore, creams intended for a child’s skin require a specific formulation because if it is different in its structure, it will also be different in its function. In fact, a child’s skin is more vulnerable and is less able to carry out its natural protective function.
