Nail color for me goes one of two ways. Either a pop of bold and bright or a barely-there pale pink. For years, I wore a beautiful, sheer ivory hue from Nails Inc, but had to discontinue use after suddenly developing a strange reaction (with no explanation to date).
It took me a while to find a good replacement. Not exactly the same, but equally pretty, is Dior Diorlisse Abricot in Snow Pink. One coat over the Abricot Base Coat provides the faint coverage I like.
I also discovered a very handy cuticle serum pen from Olive and June. It absorbs quickly and provides an instant refresh to my manicure or even bare nails. I like it so much, I have one for my car, my desk, and my nightstand.
