Are there any ointments that are effective for acne?

Acne is a big worry for everyone~

I am also very stressed because of acne. I am wondering if there are any effective acne ointments among those commonly used at pharmacies or clinics. I saw a lot of recommendations for Acnon and Noscar shown in the picture. Do they really work?

I would appreciate it if you could recommend an acne ointment that is gentle on the skin and helpful for whiteheads or inflammatory acne. Please also let me know the usage instructions and precautions. I would also appreciate it if you could explain the criteria for selecting an acne ointment for troubled areas and the differences in ingredients.
