i use IPSA....cus there's 3 colors so i always mix my own color depending on what the problem is (ex: small pimple or dark eye circle).
my friend has SEVERE dark eye circle...& she used the YSL radiance pen... i bought it with her, & it worked like magic. here eye circle is pretty dark (plus she has dark skin), & in her eye area, there are some veins...but that YSL was able to cover it very very very good.
