Skin temperature changes the pace of development
Warmer skin can make some materials evaporate faster, so the opening may feel brighter or shorter.
Moisture can affect how long the scent stays noticeable
Very dry skin can make some fragrances seem quieter sooner. Applying an unscented moisturizer may help the fragrance stay detectable for longer.
Spray count and placement matter
A heavy application in one area can smell different from a lighter application spread across a few points.
Weather and clothing change the experience
Heat, humidity, cold and fabric type all affect evaporation and how easily the fragrance is noticed.
Test on your own skin before deciding
Blotters are useful for a first comparison, but wearing a fragrance for several hours on skin gives a better picture before buying a full bottle.
