There are different ways to achieve a flawless skin after acne and it needs medical interventions. Acne treatment has multiple stages - to control new breakouts, to clear the sequalae (pigmentation and scars) and to prevent a relapse. Acne scar and pores can be treated with subcision, dermaroller, fractional CO2 lasers, chemical peels and likewise. So you see there are options other than lasers. Discuss them with your dermatologist. Lasers are very effective but still there are ways without them to make skin healthier and better.
