Siam Opium Giangregorio Cosimo
Siam Opium is a unisex perfume by Giangregorio Cosimo, released in 2025.
The Italian brand creates fragrances in perfume and extrait concentrations, so this release is intended for those who appreciate a rich scent profile, expressive longevity and a noticeable presence.
In character, Siam Opium combines balsamic and fougère facets. It brings together green freshness, spicy sparkle, aromatic herbs, warm resins and a soft gourmand sweetness.
This combination makes the perfume gender-neutral: it may unfold differently depending on skin temperature, weather and the individual way it is applied.
Character and development
The opening feels bright and contrasting: citrusy lime and pink pepper add dynamism, elemi brings a resinous-balsamic nuance, while a green cannabis note immediately gives the fragrance an unusual, contemporary accent.
As it develops, the fresh sparkle becomes calmer, giving way to a herbal, spicy-aromatic heart.
In its trail, Siam Opium is presented as a fragrance with very strong projection.
It is an expressive choice for evenings, cool weather, special occasions and situations when you want to leave a noticeable olfactory impression.
In a warm room or at high temperatures, the composition may smell especially intense, so it is best to start with a small number of sprays.
Concentration and wearability
Siam Opium is available in a perfume, or extrait, concentration.
This format emphasizes the composition’s density and depth, while helping its balsamic, woody and ambery facets linger longer on the skin.
Other concentrations of this fragrance are not listed in the database.
No precise recommendation for application to skin or clothing has been provided.
Given its very strong trail, it is sensible to start with one spray on the skin and assess the development after 15–20 minutes; on clothing, the fragrance should be applied especially carefully, avoiding delicate fabrics and light-colored materials.
Siam Opium will appeal to those who enjoy noticeable extraits, unconventional green accents and rich resinous bases.
Its place in the brand’s style
For Giangregorio Cosimo, this release demonstrates an interest in expressive niche perfumery, where familiar fougère and balsamic directions receive a bolder interpretation.
In Siam Opium, a classic herbal theme meets ambery warmth, vanilla softness and a dense woody-resinous backdrop, making the fragrance feel cohesive and distinctive.
What to compare Siam Opium with
If you would like to continue exploring rich compositions, consider Edgardio Chilini Pineapple Sorbet, The Spirit of Dubai Oud and Dior Eau Sauvage Extreme (2010).
They differ in mood and emphasis, but may appeal to fans of noticeable projection, long-lasting bases and fragrances with a strong individuality.
