Hey Imgorgeous, yes I hate when my questions aren't answered too because I really want to know stuff and to achieve my goal. I only copied and pasted this formula but I never made my own formula before but hope to by the fall maybe with sepiwhite, alpha arbutin, kojic acid, and anything else I can find. Though I nolonger use hq, this formula seems pretty good. I'm not sure if there is a preparation difference with hq crystals and hq powder.
But, in the article someone name Walter H. Wood, M.D. stated that this is his variation of formula originally from Walter H. Wood, M.D. (Dr. Walters is posted there too if you want to try). You can try contacting this dermatologist for more info if he would give: his office number is (408) 286-4600, I found it on this site here

"Topical hydroquinone comes in 2% (available in cosmetics) to 4% (or more) concentrations (available from a physician or by prescription), alone or in combination with tretinoin 0.05% to 0.1%. Research has shown hydroquinone and tretinoin to be powerful tools against sun- or hormone-induced melasma... Some research has shown topical azelaic acid in 15% to 20% concentrations to be as efficacious as hydroquinone with a decreased risk of irritation."
-Proplyene glycol-used as a moisturizer, also suggested is glycerin
-Eucerene Cream-or other good moisturizing lotion
-Retin A- aka Tretinoin, a derivative of Vitamin A used for acne and hyperpigmentation. "the outermost skin layer thins and the cells in the epidermis level produces a thickened epidermis layer."
-Lidex cream-type of steroid cream (be careful w/ streroids though). Used to treat inflammation and itching... also thins the skin.
From what I have read, you have to dilute 2-4% in either alcohol or water. I think the best thing to do is contact the supplier who you purchased it from, a hq crystal vender, pharmacist, or online science lab and ask for the accurate dilution and formulation for the hydroquinone crystals for cosmetic use. Here is a post from this site also asking about dilution instructions and more info:

Someone also stated on the post that the hq was 1st mixed in a skin crème in a jar that's not clear, closed it tightly and then placed it in a pot of boiling water for about 10min until it dissolved, let it set & not open it for some time. Also which was important as quoted "Hydroquinone is light and air sensitive so to stop it from turning brown you have to make sure the powder is fully dissolved, kept in an air tight container and kept in a container that is not clear. The container that I have is clear so i keep it in a brown paper bag."
... Personally I would think all you need is a good moisturizing creme/lotion after you dilute the hydroquinone and use a exfoliating soap like papaya kojic acid soap, or something similar before applying the cream to help the crème to work well. I hope this helps.
