A practical guide to the perfume pyramid.
These notes last the longest on the skin, and are what you smell during your fragrance's dry down. Think of them as the building blocks of perfume. Having trouble getting your perfume to last? You're probably not using enough base notes.
The molecules in these notes are literally lighter, so they evaporate first (sometimes within seconds). This category contains most citrus notes, which happen to be some of the most universally appealing aromas - giving you that have-to-have-it feeling fresh out of the bottle.
