Guerlain releases a special edition for Muguet every year, to celebrate the arrival of Spring. Muguet was first released c1904. There was a reformulation in 1998 (which was rereleased in 1999). A new version was launched in 2006 and since then it’s been customary to release a new version annually. In 2016 Muguet was reformulated by Thierry Wasser, and this version was still used for Muguet 2024.
