Mild Glycolic peel 5 weeks ago: my skin is a shade darker and dull and glowless.

I got a mild glycolic peel done by dermatologist a month back and i dint see any noticeable peeling for a week though i was feeling extremely dry but i kept applying the creams and sunscreens prescribed by my dermatologist whole day through. My skin became very dark and glowless after a week. I waited hoping it to get better, now the darkness is not that intense but is still face skin is a shade darker, dull and absolutely glowless. Will it recover or remain same or can anything be done.?
