Is the effectiveness of the acne treatment good considering the cost?

I'm looking into acne treatments, but I'm hesitant because the cost is higher than I expected.
It is more of a burden to hear that the acne treatment isn't a one-time thing but requires consistent sessions.
Still, I've heard it's worth the investment if your skin improves, so I'm curious about the satisfaction level of those who have actually seen results.
I want to know if receiving acne treatments consistently definitely reduces breakouts.
I want to hear an honest review on whether it was cost-effective.
