I urge everyone to bookmark that blog; it is always a fascinating tour of the weirder and wonderfuller places on our planet. And let me leave you with this simply jaw-dropping video of undulatus asperatus in action.
(A sunscreen with a physical block like titanium dioxide or zinc oxide can be applied last, after a serum or moisturizer.) Apply a serum next and, finally, moisturizer if you need it. Polis also recommends serums or sunscreens with moisturizers built in because they save time.
And this means I can use it with a derma roller, which is exactly what I'm going to do. As I said before, I was advised not to use a derma roller with needles longer than 0.2mm, so I am going to use 0.2mm and roll very gently in this area before I apply the serum. Honestly, I am not expecting any miracles ... Other cause is (what else) aging: As we age the sensitive skin under our eyes gets thinner, we also lose some fat in this area which gives it volume. 2  The result is a depressed area that casts a shadow. 3  Dark circles sometimes look worse because dark (usually blue) veins start to show through the half transparent skin.
