My question is are triluma and the ingredients in Obagi nu Derm kit (medical grade) ok to use together? (photos)

I am 42 year old female with mild to moderate sun spots and premature aging. Regardless of consistent use of broadspectrum sunscreen and religious sun avoidance my age spots seem to be increasing / worsening. I've been seeing a dermatologist and have tried numerous products and am now gonna give triluma another chance. I have heard wonders about Obagi's Nuderm Kit (medical grade) and would like to try this as well. My question is it okay to use both Triluma and Obagi Nuderm (medical grade) kit as well?
