Demeter Rain Perfume by Demeter, Demeter rain, a unisex fragrance, welcomed spring showers when it was launched by the fragrance house of demeter in april of 2009. Even just a quick smell of the perfume transports you to the outdoors after a heavy downpour, where you take in the aromas of fresh rain and wet earth. The scent has a refreshingly simple composition and features only rejuvenating and renewing rain notes.
