Why does one clary sage perfume last 11 hours in Indian heat and another only 8?

The difference comes down to how each perfume is made, not the clary sage itself. For Him Musc Santal Intense lasts about 8 hours because it is softer and more intimate. Polo 67 Eau de Parfum Extreme lasts about 11 hours because it uses stronger, longer-lasting ingredients around the sage. Clary sage smells clean, slightly herbal, and a bit like fresh tea. In India or UAE humidity, it can fade fast, so pick a longer-lasting version for outdoor events. For quick errands, the shorter one works fine.
