Subcision, which is a relatively inexpensive procedure that I have personally been performing since 1995, has a proven track record for elevating and smoothing all kinds of indented scars from all causes, including those from chickenpox. Since all the work of subcision is done below the scar (no cutting, stitches or wounding of the surface), it can be used safely in all skin types. It takes only a few minutes to perform in experienced hands, and there is typically little to no significant downtime. In the days before the pandemic, when people worked in offices, my patients would often come during a lunch break and then return immediately to work. You would be wise to consult with an experienced, board certified cosmetic dermatologist experienced in subcision. Surgical revision surgery, especially in areas subject to a great deal of movement, run the risk for the subsequent development of unsightly stretch scars and tram track stitch marks. Be very cautious when, as you no doubt will be, offered this or that expensive, supposedly "next big thing" fraxel laser or RF treatment, as these are far more backed by social influencer and device manufacturer marketing hype rather than any hard science. Hope this helps and best of luck.
