My sixth-grade son is worried about his acne.

My sixth-grade son's face is covered with acne. Even after visiting the hospital, it only improves temporarily. Since he has very oily skin, I make sure he cleans his face thoroughly and applies medication diligently. It gets better, but if I neglect his skincare even a little, the acne flares up again.

The child is also under a lot of stress.

Please share any helpful advice or effective treatments you have experienced.
