What cleansing products are suitable for children? (Upper elementary grades)

My eldest child is in 6th grade, and lately, small pimples have been popping up all over their forehead and face, possibly due to hormones. People around me say I need to use a cleansing product, but I'm not sure what to use. The one I use is for removing makeup, so I think it might be too strong. What cleansing products would be suitable for older elementary students?
