I am a student, and I have huge cystic acne scars on my nose. I am getting laser sessions for the same, in a local clinic. But, even after three sessions, my skin shows no difference. Those marks look raised and terrible. Should I discontinue the treatment as it is extremely expensive for me as a student? I am using Tru face wash at night and sunscreen twice a day. I am also using Benzoyl peroxide cream in the evening and Tretinoin cream at night. I also take oral tablets as prescribed by my doctor.
