    Omg! This is the best lip serum/balm ever!!

    I love the way it makes my lips feel. I use a little as a gloss over lip stain and more at night to really improve the look and feel of my lips.

    LOVE

    I absolutely love this product! I received a free mini with an order I recently purchased and it will be replacing my current go-to lip product. It’s hydrating, and lasts a long time. Kosas has done it again :)
