Can an Obagi Blue Peel Get Rid of Dermal Hyperpigmentation?

The stronger the concentration of TCA that is used during
the Blue Peel, the deeper it will penetrate.
Sometimes more than one coat is needed, as well as a series of peels a
month or six weeks apart. Prior to
proceeding with a Blue Peel, I would recommend getting involved with a good
skin care regimen in order to maximize the health of the skin or “turbo charge
it” so that the skin should be able to heel very quickly after a Blue
Peel. At the time of your consultation
with the plastic surgeon, it is important that you discuss what your goal is
for the Blue Peel so they can decide the appropriate level and number of coats
that would be needed.

I would not suggest an Obagi Blue Peel for your situation of lip hyperpigmentation.  The likelihood  that this treatment will improve the hyperpigmentation is low and there is a chance that it could make the situation worse.  I agree with my colleagues, topical bleaching creams including tretinoin and hydroquinone would be the safest and best option.  We also use the Obagi Nu-derm System, which incorporates the above medications, and have found that it works reasonably well for your situation.
