Chemistry help..?

[Jjoy]

Well not for a class or anything. I am actually trying to make something and am confused. I don't really know where to ask this lol.

Okay so say I am using a lotion, cream, or serum base from a wholesale site. Like this one..

The base is just unscented lotion, cream or serum in bulk. You can add oils and such for scent. But it is perserved already and a solid base.

What I am trying to do is make my own skin lightening lotion, cream, or serum (they are different :P lol) and since I only want it to even my skin out I wont be buying any of the store brand ones. Instead I want to add Alpha-Arbutin, from here. It's in a powder form.

Now I am not sure if just mixing the powder form alpha arbutin to a lotion,cream or serum base would be effective because on the Alpha-Arbutin page under "use" it says this..

Use: Recommended concentration 0.2-2%, add to water phase of formula, best results use product containing Alpha-Arbutin for at least 2-3 months.

So does this mean I would have to get a whatever base I use down to some sort of "water phase" and then add the Alpha-Arbutin for it to be effective..or is this just 'recommended' but not required? because I'm not sure how I would get cream, lotion or serum down to a "water phase" I remember that term from high school though..I suppose I could melt it and hope it firms back up when it cools.

Sorry this is so long >_< lol please help
