    Plastic smell very off-putting

    The serum worked fine but I found the very strong plastic smell made me not want to use it, so if you're sensitive to smell in your skin care, this serum may not be for you. The hyaluronic serum is fragrance free and I liked that one way better.

    Boosts my hyaluronic routine

    It acts like a boost and seal to my routine with base layer of hyaluronic acid. It’s not as watery however, and has a oilier/more solid gel texture
