5. Sephora by OPI Nail Brightener
Price: $9.50 at sephora.com
A cure for those yellowish, lifeless-looking nails and a great thing to have in your first aid kit! Now, I don’t know how you deal with the issue of yellow nails after using dark nail polishes but the only thing I could do before I got smart enough to get a brightener is pray I’ve remembered to bring a base coat or that my fiancé didn’t accidentally throw away a perfectly good nail polish I’ve left there . Yup, living in two countries can be a b#tch.
