Is it possible to completely cure adult acne by visiting a dermatologist or a beauty salon?

I am an office worker who is under a lot of stress because of adult acne. My skin was actually quite clear during my school years, but since becoming an adult, red, hard, pustular acne keeps popping up around my chin and cheeks.

I am considering getting laser treatments or extractions at a dermatology clinic because home care is simply not enough. However, many people around me say that acne treatment is only temporary and that the condition will return to its original state if I stop spending money. I am wondering if a fundamental 'complete cure' is truly possible if I invest a significant amount of money in consistent treatment.

Or, unless I change my constitution or eating habits, do I have to live with this for the rest of my life and just soothe it whenever it arises?
