The longevity of a twin fragrance on the skin can vary greatly and depends on several factors, including the quality of the fragrance materials used, the concentration of fragrance oils and individual skin chemistry. In general, many perfume dupes are formulated to come as close as possible to the original scent, but they often use cheaper or less long-lasting ingredients. While high-end designer perfumes frequently contain exclusive essences and special fixatives to keep the fragrance stable for hours, these are often missing or present in lower concentrations in many dupes.
Typically, a twin fragrance lasts between two and six hours on the skin. Immediately after application, the scent can be very intense and similar to the original, but it often fades more quickly or changes more noticeably over time. The base notes in particular, which are responsible for long-lasting performance, are often less pronounced or less stable in dupes than in expensive perfumes. Eau de Parfum dupes generally have better longevity than Eau de Toilette versions because they contain a higher proportion of fragrance oils.
Individual skin type also plays a role: on oily or well-moisturized skin, a fragrance usually lasts longer than on dry skin, as the oils in the skin bind the fragrance molecules better. The way you apply it can also influence longevity – applying it to well-moisturized skin, to warm areas of the body such as the wrists or behind the ears, and avoiding rubbing after application can all help the scent last longer.
In summary, fragrance twins can have a similar scent effect to the original, but in most cases they do not offer the same longevity. Those who want to extend the scent’s performance can layer the fragrance by using a suitable unscented lotion as a base or by spraying the perfume onto clothing, where it often remains noticeable for longer.
