Swelling and Hyperpigmentation After Microdermabrasion and Chemical Peel

Dear Janet,
There are a lot of variables in how microdermabrasion and peels are done. The same concentration peel can have very different effects depending on how wet the agent is applied, how vigorously it is scrubbed in, how the skin is prepared. For example if the microdermabrasion done prior to the peel is done more aggressively and then the peel is performed following this, the effect of the peel will be much greater. This probably accounts for the difference in results.
Triluma, a dermatologial agent that contains a steroid, Retin A, and a skin bleacher may help speed up the resolution of the post inflammatory hyperpigmentation you are experiencing. There are other options as well.
I would encourage you to be seen by the doctor who performed the treatment. This doctor is likely to be highly motivated to help you. If you are simply too uncomfortable seeing this doctor, look for a cosmetic dermatologist in your community with a good reputation. Often the cosmetic dermatologist in a large dermatology group is a safe bet if your community has such a group.

You really should go back to your treating physician. If you had this treatment before without problems then something must have happened to make you react in such a way. The sooner you get on skin lightening medications the better so you should be seen ASAP. We can only speculate on what might have happened so the best person to treat you at this point is the one who administered the treatments.

It is likely that either the microdermabrasion or peel were too aggressive for your most recent treatment.
At this point, use of tretinoin cream, short course of a mild topical cortisone cream and bleaching agents such as hydroquinone can help the pigmentation resolve faster. If your skin becomes irritated/red with tretinoin cream and hydroquinone, it is important to dilute them with moisturizer and/or apply them less frequently because the irritation can promote more brown pigmentation.
I would also continue to protect yourself from the sun with broad spectrum sunscreens and minimize sun exposure.
You may want to find out what was different about your last treatment so you can avoid this complication in the future.
Good luck.
