I had upper and lower Blepharoplasty (with fat repositioning) 3 weeks ago. Still quite bruised with swelling. (photo)

That bruise can persist for 4 weeks, and even longer.  However, they do eventually fade.  So I agree, you are doing well.  And yes, IPL can help remove the bruise.

You look like you are healing well - just have some stubborn bruises.  I would recommend warm compresses to the lower lids which can help speed up the resolution.  Also, you could ask your surgeon if they have an IPL or pulsed dye laser.  Treatment with either of these has been shown to help with bruising.  With time it will all resolve!
