Thank you for your query. Severe acne pits would require a little intensive treatments like dermaroller, laser or microneedling along with chemical peeling at different intervals. Cost would vary from place to place. Regards

Greetings. Peel is one of the modalities for pigmented post acne scars and helps in resurfacing to minimal extent. For actual pitted scars, you'll need acne resurfacing modalities like fractional co 2 laser or micro needling rf . the cost may vary depending on the machine used. See a qualified dermatologist near you. Further queries may be sent on follow up messaging. Warm regards
