Might it be overkill?. I don't want to do too much and darken.. but I feel like I may be just kind of staying the same.. I got fats results so it seemsed with the HQ but not it seems I'm staying the same... or maybe even just going back to my normal... so I wanted to know if anybody knows if adding my arbutin lotion of 15% or so again to my regimine and keeping the HQ4 Retin A might improve my results do the opposite?
