Although the resolution of the photos leaves something to be desired, it is likely that the depigmented, whitish areas you describe are patches of postinflammatory hyPOpigmentation, i.e. loss of pigmentation as the aftermath to the IPL treatments you received. If this is indeed so, then there is a possibility that discontinuing any further treatments, with time, these regions may spontaneously repigment. If they do not, or if you wish to expedite the process, microneedling supplemented by the topical applications of tyrosine and lanatoprost may help to repigment them. Microneedling possesses the potential to autotransplant pigment producing cells from the normal areas surrounding the hypopigmented ones, as well as for creating microchannels in the skin that permit the penetration of tyrosine (an essential amino acid in normal pigment production) and lanatoprost (a pigment stimulating agent). You would be wise to seek consultation and treatment by a board certified aesthetic physician and ask to see his/her before and after photos before agreeing to proceed. Be cautious about falling prey to the heavy marketing and advertising for treatments with this or that supposedly latest greatest light and energy-based devices. Best of luck to you.
