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?

You can try. I used a "high percent" arbutin alone on my face for about a month and it didn't do anything for me. Good luck!

Arbutin is not that strong,it gives a brightening effect and can lighten up to one shade nothing more..

Which arbutin are you referring too? There are several, most popular are:

Beta arbutin (aka bearberry aka "arbutin")

Alpha arbutin (synthetic arbutin, more potent than beta arbutin)

Deoxy arbutin (highly potent more than hq, isn't cytotoxic, rarely used due to extreme high price)

Girl you know I can't afford Deoxyl.. LOL... Alpha... all the way

Lol... yeah true with alpha prices. But I'm hoping they'll drop the pricing one of these days so it can be more widely used. Some very potent stuff.
