A doctor recently gave me Tretinoin and Hydroquinone to battle my age spots and fine lines. I also just signed up for red light therapy at the tanning salon (I will not be tanning. I will only be using the red light bed and doing an occasional air brush spray tan). It is ok to do all three treatments together as long as a rotate days for the creams which I will do in the evening and do the red light during the day?
