Mole Removed on Face Via Shave Excision - Slight Bump and Brownish Scar Left?

It may take several months and even up to one year for scars to have their final results.  I would encourage you to be patient during this time.  If the redness still persists it may be possible to treat with IPL laser.  

Scars will take their time in terms of final results.  If the scars bother you, I would begin treatment with Melaquin cream followed by pulsed dye laser for both scars to reduce the red tone.

If the mole was shave flat the discoloration you see could be remaining  bits of mole still deep in the skin (which would have to be excised to remove)  or post-inflammatory hyperpigmentation (which will likely faded0.  The bump is likely just an inflammatory reaction to recent surgery.  It will take several months to see what the area finally looks like so be patient.
