Love by Kilian is an overwhelmingly sweet gourmand fragrance with a bombastic opening of sugary white florals, citrus, and vanilla, followed by a deep, furry vanilla and caramel base. The scent is consistently described as a fluffy, marshmallowy, bubblegum-like cloud with an underlying animalic muskiness. While the perfume is praised for its intense sillage and long-lasting presence on skin and clothing, many reviewers emphasize its juvenile, juvenile, and extremely sweet character. The perfume is most beloved during cooler weather and is frequently described as having a nostalgic, childhood-associated feel—reminding some of Fruity Pebbles, Lemon Squeeze candy, or frosty pink winter caramels. Many users appreciate its 'cool' energy, collectability, and captivating performance as a signature scent. However, the perfume is also criticized for being noticeably thick, poorly blended, overpriced, and having poor longevity despite high expectations. A significant number of users avoid it entirely due to its cloying sweet profile and musty animalic civet note, which some find nauseating.
