Siren

Impulse Siren is a floral, aquatic, and woody fragrance. The opening is aquatic and fresh. the heart settles on floral. the dry-down rests on woody.

Impulse Siren is estimated to last 6–8 hrs on skin (a 4/5 longevity score). This is derived from the base-note composition — heavier base families like oriental, woody, and leather extend wear, while citrus-led blends tend to fade faster.

Impulse Siren projects at a moderate level (3/5 sillage). Expect it to be noticeable within arm's reach without overpowering the room.

Impulse Siren is best worn during spring, summer, autumn, and winter. The note profile makes it well suited to daily wear, date night, evening, sport / outdoor, and formal. ScentCast pairs it with live weather and your calendar so you only reach for it on the right days.

Based on the note structure, a single morning application usually carries through the full day. Heat and humidity will shorten longevity; cooler weather and moisturised skin will extend it.

Impulse Siren fits collectors looking for floral, aquatic, and woody signature.
