These atrophic scars are broadly classified as rolling, ice pick and boxcar type. The treatment modalities will depend on the type of scars you have. Various techniques are: CROSS (chemical reconstruction of skin scar - done by using various chemicals), different types of dermatosurgeries like subdivision. Even Lasers may be used. The cost depends on the type of modality chosen and also on the number of sittings.  Chat Doctor.  </s>
