The product information does not state a specific age. It is described as a gentle toilet soap for washing hands and body, and the "children's" name refers to the intended audience rather than a precise age limit. For older children who can wash and rinse on their own, it is a normal choice for everyday hand washing and freshening up after school or outdoor play.
For babies and toddlers, the skin is thinner and more delicate, and the product description does not mention use on infants. If you are considering it for a baby, it is safer to ask a pediatrician or family doctor first, or choose a cleanser specifically labelled for babies. If you are unsure, start by using it only for hand washing; if the skin stays comfortable after several days, you can decide whether to use it for body washing. For any child, avoid contact with the eyes, and if the skin becomes red or irritated, stop using the product.
Adults can also use this bar if they prefer a simple, classic cleanser without a heavy residue; the "children's" label does not restrict it to children.
