I *love* my lip fusionXL, it provides the absolute best in lip-plumping and I have tried many products. I actually use mine during the day, although occasionally at night. If I use it once a day my lips are INCREDIBLY full. Once it wears off, my lips still are full, soft, and supple. The plumping benefits last me at least a day and sometimes into the next day. it has marine coligen and hyalronic acid that sets it apart from most cinnamon and spicy lipglosses this actually has ingredients that actually build your natural collegen for lasting results that is way worth it...I am so satisfied with this product, I will never buy another lip plumping product again!! Even though this product is expensive, it has lasted me several months and I still have some left (granted, sometimes I don't use it religiously). I will definately repurchase in the future. I love my lipfusion; it does what it claims!!!!
