iope sunblock white spf47

I have been searching for a powerful sunblock with whitening power to prevent pigmentation (freckles and sun spots) for a while now.  My sister recently bought the Laneige Star White Multi-protector and it has what I want in it...BUT it's so darn sticky on the skin.

I've gotten so used to Shiseido's super liquidy sunblock that I cannot stand the sticky residue the Laneige sunblock leaves behind.  One of my coworkers says she uses the Iope Sunblock white and she really likes it.  I tried it on in the store on my arm and it does feel LESS sticky than the laneige sunblock. However, it is still a cream.  I have yet to find a different whitening sunblock that is affordable.  The Iope one is around $35 for only 2 fl.oz. so that's already gosh darn expensive for a sunblock.  I heard the Dior Snow sunblock is good but it's around $50 (more than I'm willing to spend).

I've been searching online for reviews of the Iope sunblock but alas, to no avail!  Has anyone tried this sunblock besides my coworker??? Is it even suitable for younger skin? *SIGH*  I wish they gave out samples so I could try it on my face for a few days.  This really stinks.
