Hey, I came across your posts and realized we have the same exact skin (SD, rosacea), and especially the flakey pores with excess sebum/keratin. I have not been able to get rid of mine for years either. Whenever I stretch my chin I can see the tips of the flake hanging out, though I can't see the pore because they are smaller on my chin. I also have this problem on my cheeks and nose, too.
I was just wondering if you have made any progress yet?
I'm almost positive that the extreme amount of oil my (our) face produces is the cause for all these problems...
