I have been using Birchbox consistently for the last three years and this is by far one of my all time favorite products! It delivers on every promise from moisturizing to plumping & reducing fine lines. Several of my friends have purchased this after trying mine.
FIRST TIME USERS: In order to see significant results in terms of overall plumpness and youthfulness of lips, make sure you use it at least twice a day. I use morning, afternoon and right before bed!
