After IPL my skin had very dark "peppering", will this go away? (photos)

Thank you for your question. It is expected for the areas of hyperpigmentation to become much darker and slough off similar to coffee grounds after treatment with IPL. Should this area become more red, tender, swollen, or the skin not intact be sure to follow up immediately with your provider.

Thanks for your question and posting pictures.  Believe it or not, it looks like you received a great treatment.  The peppering is caused by underlying pigment that is being broken up and brought to the surface.  Your skin is purging the pigment that you wanted eliminated by the IPL.  It should clear up in the next couple of days.  Each time you do an IPL, usually less comes to the surface, but it really depends on how much hyperpigmentation was present when you started.  I hope this helps.
