Tummy Tuck Scar After 10 Weeks - Hyperpigmentation Problem

Hi-
I understand your concern about your scar- but your interests and final outcome will be best served by exercising as much patience as you can muster... human scars mature over the first 12-18 months after they are created, meaning that for that time period, the scars will improve in appearance on their own (even if nothing were done). After this time period, you can be confident that no further improvement will occur, and intervention would be appropriate.
I don't blame you if you don't want to wait that long to see some improvement, but because the scar will be undergoing this improvement over that time, anything you do will affect this normal maturation process- so be careful, and don't be too aggressive too early in the process.
I usually recommend simple, easy, low risk scar treatments first- even if you don't get the complete improvement you wanted from them, the low risk nature of these options will mean it's unlikely you'll regret them later too- and you haven't burnt other bridges either. Examples of these kinds of simple things are Scarguard gel, Silicone tape, and Abdo-patches (from Medical Z).
If these interventions don't give you the improvement you want, then you can consider IPL (intense pulsed light) treatments or other options like bleaching creams.
Remember- the scar is likely to improve significantly on its own- the best thing to do is to try not to get in its way.
Happy Holidays!

Your scars are still pretty fresh and will be more prominent at this time. Take care of them and protect against sun exposure. With time, they'll fade, but you have to wait for about year for this to happen. Ask your surgeon what treatments you can do to help expedite the healing process.

                  Wound
healing is a dynamic process that continues for 12-18 months following
surgery.  During this period,
wounds undergo a series of changes which hopefully result in imperceptible
scars.

                   It’s
not unusual for wounds to discolor during the initial phases of wound healing
for a variety of reasons.  In most
cases a slight reddish discoloration is present which is related to increased
blood flow.  This is an entirely
normal phenomena and is necessary for normal wound healing.

                   Unfortunately,
your case has been complicated by a hematoma.  This problem will probably delay your wound healing
response, but won’t stop it.

                   At
this point in time your wound needs time to heal.  It’s important that you discuss these issues with your
plastic surgeon.  It’s also
important to be patient and allow normal healing to take
place.
