Hi Jill, thank you for contacting Renewme Skin Clinic.
Here is some information about the basic acne scar treatments we provide at our clinic, which includes a laser subcision called INNOfill: http://rnmeskin.blogspot.kr/2015/09/basic-treatment-combo-for.html
Generally, monthly sessions are recommended if you want to see best results. One time treatment may still help improve your scars a little. Price for fractional laser only is 700,000 KRW, INNOfill only is 750,000 KRW, and a combination of the two costs 1,000,000 KRW (10% VAT for card payments).
Please let me know if we can help you with anything else. Our consultants are available over email, Kakao Talk, Line, WhatsApp, phone, etc.
