Self-tanning tips:
Definitely exfoliate. Then before applying tanner, apply extra moisturizer to any areas that tend to over-tan, like tops of feet, ankles, knees, elbows, etc. Apply several thin coats of tanner rather than one heavy coat. I wear surgical gloves. After I've done my body, I rub a small squirt of tanner on the backs of my hands, feathering lightly at the edges so there's no line of demarkation.
Brands I like: Since I'm a volume user, I stick to the cheap ones I can get at the drugstore. I like Banana Boat, Neutrogena, Bain de Sole (no idea how to spell that!).
As for the dark spots in the pores, I used to get this on my shins. Now when I shave my shins, I shave upwards AND downwards. For some reason this has helped.
