9 Spring 2025 Perfume Trends Predicted By Experts

Whether you want to personalize your signature scent or just want to smell expensive, a perfume enhancer is a worthy investment. According to Karl Neale, co-founder of Rebel Aromas, these are “foundation fragrances” that have very simple scent profiles — mainly ambroxan, a lab-made version of popular perfume note ambergris — a rare substance from sperm whales. “You can wear perfume enhancers on their own for that ‘clean skin’ scent, but they’ve been formulated to blend perfumes when layering. They add depth, boost scent projection, and improve longevity,” says Neale.
