How long will it take before I stop feeling tired after laser resurfacing? (Photo)

This is not a typical issue from laser resurfacing I suggest seeing your physician and/or a psychologist to see if there is other life events that are affecting your mood.  some people feel depressed after laser resurfacing which also could be affecting your mood.  There is no reason why not to speak to someone about it and get a formal internal evaluation (hormones, vitamins etc).  Best, Dr. Emer.

The laser procedure itself should not produce any fatigue, but it is possible that any systemic anesthesia used during the procedure could.  If you had a general anesthesia for the procedure, this sometimes can produce some fatigue but normally this would resolve fairly soon.  If you have not already, I would alert the physician who treated you about your issue so that you can be evaluated if needed.
