Hi,
For improving the cosmetic appearance of your old healed chickenpox scars, you may consult a dermatologist again. In my opinion, surgery will not be required. Results of conservative treatment tend to be mixed. Usually, such lesions tend to fade as time goes by, and many of these eventually disappear completely.
