Sigh, I'm sorry. Unfortunately, the short answer is "no" hypopigmentation doesn't resolve. Because in essence the pigment has been removed from there, and you cannot get it back. You can try to have further IPL (from a doctor's office only!!) to lighten the skin around the very hypopigmented...
Sometimes after a procedure like this, the skin can become irritated. If there is redness and itching, it may be fine to use some hydrocortisone 1% cream. If it persists, I would encourage you to see your physician.
The coffee ground spots that you are experiencing is a good sign that the IPL treatment was effective. The pigment will usually take 1-2 weeks to flake off. There may be swelling, but it is fine to wear make-up after treatment. We recommend mineral based make-up and a good spf....
