P-Scab Soap contains permethrin, which treats scabies, and calendula, which soothes the skin. Children’s skin is more sensitive, so it should not be used on its own. For a 5-year-old, the safest approach is to consult a paediatrician first. If the doctor advises its use, follow their instructions carefully, use a small amount, rinse thoroughly, and monitor for any redness or irritation.
