I have dry skin and v dry undereyes. Almost all concealers look flaky & dry after a few hours.
Anyway I became intrigued by the new 'serum' concealers & bought 3! I tend to go down rat holes
Best by far is the Bare Minerals Bare Skin Serum concealer. Lovely texture & nice coverage. I set with a very fine powder (NARS Crystal Light setting powder)
Also lovely was a loreal serum concealer in the clicky pen format. Brilliant but hard to find and not cost effective when you factor in the tiny amount of product in those clicky pen things.
Bobbi Brown serum concealer was ok, but BM was more moisturising & better coverage.
