Use Triluma on Dark Areas of Scar Only?

In my practice, I try to stay away from these combination regimens, as cortisones are non-selective inhibitors of melanocytes.  I would recommend my patients to start Melarase AM and Melarase PM for the pigmentation.
I would start with an intense skin rejuvenation protocol for age spots that includes fractional laser, Covalent chemical peels, and daily skin brightening creams to improve your skin’s complexion. Laser therapy, he adds, must be combined with a proper skin regimen to enhance and maintain youthful results.
He recommends the following skincare products for dark age spots: Melarase
MelaClenz Brightening CleanserMelarase AM: Day-time skin lightener with SPF 30Melarase PM: Night-time skin lightenerMelapads: Daily Exfoliating PadsReplenish Retinoid Cream: Exfoliating and skin-stimulating night creamBest,

I would only use the Triluma as directed by your physician.
Remember, Triluma has a bleaching agent (Hydroquinone 4%) a retinoic acid as well as a steroid component. Prolonged skin exposure to the steroid can cause detrimental effects of thinning the dermis and resultant damage to the skin. I only allow my patients to use the Triluma for 6 weeks and then abstain for at least 2-3 months. This may be viewed as conservative, but I have as yet to experience any significant side effects and use the porduct often.
I hope this helps!
