I've never heard of it.  So I looked in the book "Don't go to the Cosmetics Counter Without Me."  The author gives the skin care averge to below average ratings.  She gives the foundations below average because of the colors, concealer below average, powder average, blush average.  She did give the quad eye shadows an above average.  If you would like me to look at a particular product I'll be glad to.  While I don't take the book as the end all be all, it's nice to read and get an opinion about things. 

HTH

That powder is not in the book.  I think because it is new and the book is a few years old.  Honestly, if it were me, I would try if I thought it would fit my needs and was in my budget.  Most places have money back guarentees, so if you get it home and hate it, you can return it.  Let us know how you like it.

one thing about salycilic acid is that it wont do any good if it's not in the right concentration and the pH of th eproduct isn't such that the acid can work. Your best bet would be to use a salicylic acid product seperately (one that is not in an alcohol base) and use any powder. Not that that powder woulnd't be good, but the salycilic acid is prob. just a trace amount-- I can't imagine it doing much good in a powder.
anyway, thats my opinion for what it's worth. i use paulas choice salycilic product (she sells both 1 and 2% concentrations in liquid, gel, and lotion formulas) and they are not in an alcohol base- so it doesn't burn and you get the benefits of the product w/o stinging and burning from most Salycilic toners. I looked and looked for something compirable at the drugstore and couldn't come up w/ anything.
I do think that Physicians formula has silky powders however, so in that respect, try it out and see what you think.

here is a review from my paulas choice newsletter on another brand of product that she recommends for lightening, I'll paste it below:

Alpha Hydrox Spot Light Targeted Skin Lightener ($15 for 0.85 ounce). I was told that this product was in part developed by Alpha Hydrox in response to feedback from me via my earlier reviews of the company's Fade Cream. Alpha Hydrox has always done a good job in the AHA field, not only disclosing the percentage of glycolic acid used, but also formulating these types of products within a pH range that allows exfoliation to occur. Now they've launched a well-formulated, skin-lightening product that combines 2% hydroquinone with 10% glycolic acid in a base with a pH of 3.3, all in packaging that will keep the hydroquinone stable. The lightweight lotion base is suitable for normal to slightly dry or dry skin, and the only thing missing is a selection of state-of-the-art water-binding agents and more antioxidants (vitamin E is included). Still, this remains one of the better options for those who want to lighten sun- or hormone-induced brown skin discolorations, and the glycolic acid works in tandem with the hydroquinone to improve skin's appearance and texture.
