Whether fragrance twins last as long as the original perfumes depends on several factors, particularly the fragrance concentration, the ingredients used and the wearer’s skin chemistry.
Branded perfumes often contain high-quality, long-lasting fragrance materials and fixatives that keep the scent on the skin for hours. Premium essential oils, special molecules and complex development processes ensure greater longevity and a more intricate evolution of the fragrance. There are also differences in concentration: an Eau de Parfum (EdP) or Extrait de Parfum has a higher concentration of fragrance oils than an Eau de Toilette (EdT), which usually makes it last longer.
Perfume dupes or fragrance twins attempt to imitate the scent, but often use cheaper and less long-lasting ingredients. Many dupes have a lower concentration of fragrance oils and rely on quickly evaporating aroma chemicals, which is why they do not always achieve the same intensity or longevity as the original. Frequently, the scent is very similar in the first few minutes, but fades more quickly or evolves differently because the base and heart notes are less stable.
Another factor is skin chemistry: depending on whether the skin is rather dry or oily, a perfume may last for different lengths of time. Designer fragrances often contain more fixatives that help preserve the scent for hours, whereas dupes often lack these or use them in lower quality.
To sum up, fragrance twins often smell very similar in the first moments, but in most cases they do not offer the same longevity or depth as the original perfume. There are, however, exceptions where certain dupes last surprisingly long, especially when they have a high concentration of fragrance oils.
