Can Microdermabrasion and spot IPL treatment be done in the same appointment?

Yes, it is safe to perform a microdermabrasion treatment prior to an IPL treatment in the same appointment. Exfoliating the skin in advance of an IPL treatment allows for better penetration and absorption of the light and therefore, can increase the effectiveness of the IPL treatment.

In general, I would neither opt for microdermabrasion nor IPL as stand-alone or even as combined treatment modalities for treating any but the most superficial scars, and probably not even then .Microdermabrasion is little more than what was once called epidermabrasion, i.e. a superficial abrasive process for removing dead skin cells of the stratum corneum and, if performed very aggessively, also some of the uppermost portion of the epidermis. Since scars are composed of abnormal collagen bundles located within the dermis or below, little real improvement in scars can be expected from this approach. IPL is also a modality intended for superficial textural and pigmentary abnormalities and really cannot be expected to deal with scar pathology deeper below.There are many more efficient, and, in the end, more cost-effective methods for dealing with scars. Just as an example, depressed scars, after trauma, acne, infection or surgery (as in this case) may respond to subcision to stimulate native collagen production in order to elevate them and fractional medical microneedle therapy to further stimulate collagen production and improve their surface color and texture. This is just one approach. The actual therapy(ies) would depend upon the specifics of the particular scar.

Microdermabrasion can be performed before IPL without any problems and would not make your scar worse. These treatments however are not the most effective for improving scars.  Consider consulting an experienced cosmetic dermatologist or plastic surgeon for assessment.  Remember to use sun protection.
