Out of all three Rhode products, this Peptide Lip Treatment has the most reviews, so far (over $4,000). And if I were to recommend one single Rhode skin-care product, this would be it. I use it all the time. I carry it around with me and it keeps my lips hydrated and a little glossy. My recent lip combo has been a lip stain (like Benefit’s Benetint) for color, with a little bit of Rhode Peptide Lip Treatment over the top. It comes in different flavors — Salted Caramel, Watermelon, and Unscented — and mine and Bieber’s favorite is the Salted Caramel. It smells a little like Cinnabon, so you have to like having a sugar smell on your lips.
