As a clean beauty and skincare expert, I recommend using products specifically formulated for children until they reach adolescence. Adult body washes often contain stronger ingredients and fragrances that may be too harsh for a child's delicate skin. Children's body washes are typically milder, gentler, and specifically designed to suit the needs of young skin.

During childhood, it is important to prioritize products that are free from harsh chemicals, artificial fragrances, and potential irritants. Look for body washes that are labeled as "gentle," "sensitive," or "for kids." These formulations are typically milder and less likely to cause irritation or dryness.

As children reach adolescence, their skin undergoes changes, and they may require products that address specific concerns such as acne or oiliness. At this stage, it may be appropriate to transition to adult body washes, but it is still essential to choose products that are suitable for their skin type and concerns.

Always remember to read the labels, follow the manufacturer's recommendations, and consult with a pediatrician or dermatologist if you have any concerns about which products are appropriate for your child's skin.
