Why is my favorite perfume less fragrant / smells different?Updated 3 months ago

There are two usual suspects. The first is nose adaptation: you've simply grown used to the scent, and others around you can still smell it! The second is age and storage, since heat and light slowly alter the formula. If a fresh bottle smells different on you, changes in skin chemistry, hormones, medication, and diet can also shift how a fragrance develops.
