InStyle Nails is located in the busiest section of Santa Monica Blvd. -- next to the gyms, Trader Joes and Starbucks -- so it makes stopping by for a quick beauty treatment easy. It offers the full range of treatments, including manicures, pedicures, skincare, waxing and massages. It also offers eyelash extensions, and a special referral-rewards program if you tell your friends.
