The verdict: On longevity they're evenly matched (long (8-10h) vs long (8-10h)) — skin chemistry will decide. They live in the same scent territory — sweet and floral against lavender and floral — which is exactly why people cross-shop them. Yves Saint Laurent Libre stretches into spring, which Lancôme La Vie Est Belle can't cover as well.
