Perfumes with natural ingredients always smell different in batches based on the source of the ingredient while those with synthetic ingredients usually have consistency in their smell and usually last longer.
PERFUME CHANGES THROUGHT THE DAY. WHY?
Ever wondered why the smell of perfume changes throughout the day? This is due to the Top, Heart and Base notes in a perfume. When creating a fragrance, the chemistry of the skin and the raw materials used causes a perfume to evolve over time. A perfume is a very complex composition of top notes, heart notes and base notes. The top notes are the most delicate and do typically not last very long. Heart notes tend to be herbal, floral and spice notes which last longer than the top notes but you will be able to smell the base notes the longest. Base notes are usually composed from wood, amber and musk.
DOES PERFUME HAVE AN EXPIRY DATE?
The composition of a perfume might change over time. This is why it is recommended to use your perfume within 3 – 5 years. Once the bottle is opened and came into contact with air (by opening the bottle or spraying the atomiser) it should be used within the first three years. The older the fragrance gets the more different it can smell, Eau de Toilette for example might only smell of alcohol after a few years. The higher the perfume concentration, the higher the chance that it will last longer – in the bottle and as well as on your skin. Commonly, Perfumes with heavier (oriental) base notes last the longest.
