I love MAC Nylon!
I prefer using a neutral colored lip liner (which matches my natural lip color) or match it to the lipstick in particular, then I layer on the lipstick with a lip brush. I lightly dust on loose, translucent powder, and then apply another layer of lipstick.
I love shu uemura’s cleansing oil (the orange one), but most cleansing oils seem to do really well (Bobbi Brown, DHC, MAC) at breaking down long-wearing or waterproof makeup. If I have a lot of heavy eye makeup or eyeliner on, I use Lancome’s Bi-Facil!
Would Jack Black Lip Balm count? Seriously, it’s one of those products I have bought over and over again and HAVE to keep STOCKED in my house at all times. If it’s more about a color cosmetic, then I’d have to say Cle de Peau #2 Lipgloss or Chanel Dragon Rouge Allure Lacquer. Both the color and everything I associate with it.
