However, for those who love fragrances, a recurring question arises: why do certain perfumes last longer on our skin than others?

The answer lies in the complex interaction between the skin and the olfactory notes, especially when it comes to the captivating fragrances of the Orient. In this Inner Thoughts post, we will explore how skin influences the longevity of fragrances, discover the fascinating world of olfactory notes from the Orient and learn about the pH of human skin and its importance in fragrance retention.

Skin, the canvas of fragrances

Skin is the canvas on which fragrances are painted, and its unique chemistry plays a critical role in how scents develop and fade. Each skin has its unique characteristics, such as pH, humidity, temperature and the natural composition of oils and bacteria, which interact with a perfume’s scent molecules. The pH is a particularly important factor, as it can affect the stability and projection of a perfume on the skin.

The pH of Human Skin

The pH is a measure that indicates the degree of acidity or alkalinity of a substance, and ranges from 0 (very acidic) to 14 (very alkaline), with 7 being a neutral pH. Human skin generally has a slightly acidic pH, ranging between 4.5 and 5.5. This acidic pH is essential for the function of the skin barrier, which helps protect the skin from moisture loss and the entry of harmful external agents.

Importance of pH in the Longevity of Fragrances

The pH of the skin has a significant impact on how fragrances develop and last on the skin. When the pH of the skin is at its natural level, fragrances tend to adhere better and last longer. However, if the pH becomes unbalanced due to factors such as sun exposure, use of harsh products or hormonal changes, perfume molecules may interact differently with the skin, affecting their evolution and longevity.

The Olfactory Notes of the Orient and their Durability

The olfactory notes used in oriental perfumery are known for their ability to linger for hours, even days. This is due to the inclusion of rich, dense ingredients that have a longer durability on the skin.

Oud: Oud, also known as “agarwood,” is one of the most iconic ingredients in oriental perfumery. It comes from the resin of a tree and has an amazing intensity and longevity. Its captivating and complex scent can linger on the skin for days.

Amber: Amber is a warm, sensual note that is often combined with other oriental scents. Its rich, balsamic presence allows the perfume to linger noticeably on the skin.

Spices: Spices such as cinnamon, clove and cardamom are central to oriental fragrances. These potent and persistent notes are able to linger on the skin for long periods, releasing their scent gradually.

Balms: Balsams such as myrrh and benzoin are also prized for their durability and their ability to add depth and richness to fragrances.

Testing Fragrances with Mouillette

Before applying a perfume directly to the skin, it is advisable to use neutral blotting papers known as mouillette. These papers allow different fragrances to be tested without mixing with each other and also help to better appreciate the olfactory notes without the interference of the skin’s natural pH and chemistry. Simply spray the perfume on the mouillette and smell the scent gradually unfold.

Tips to Improve the Longevity of a Perfume on your Skin

Moisturise: Well-hydrated skin tends to retain fragrances better. Apply an unscented lotion before spraying your perfume to help it adhere better and last longer.

Pulse Points: Apply perfume to pulse points, such as the neck, wrists and behind the ears, as these areas tend to be warmer and help to gradually release the scent.

Fragrance Layers: Use products from the same perfume line, such as shower gels and body creams, to enhance the longevity of the fragrance on your skin.

In summary, the skin plays a fundamental role in the longevity of fragrances and perfumes, interacting with their molecules and modifying their evolution.

The pH of human skin, being slightly acidic, is essential to maintain the stability of fragrances. Olfactory notes from the East, such as oud, amber, spices and balms, are known for their ability to last over time and create captivating olfactory experiences.

Using neutral blotting papers, such as mouillette, to test fragrances allows us to better appreciate their characteristics without the influence of pH and skin chemistry.

With the right knowledge and a few practical tips, we can make the most of our favourite fragrances and enjoy their presence on our skin for longer.
