Phiero Inside Out™ by 500 Cosmetics is a scientifically formulated pheromone fragrance designed specifically for men who want to make a confident, lasting impression in both social and romantic settings. Going far beyond a conventional cologne, this innovative product works from within to support the body's own natural pheromone production, helping to amplify personal magnetism and self-assurance with every wear.
The Science Behind the Formula
At the heart of Phiero Inside Out™ is Sensfeel™, a proprietary active ingredient developed following extensive scientific research conducted at the University of the Basque Country (UPV/EHU). Unlike traditional pheromone sprays that simply apply synthetic compounds to the skin, Sensfeel™ works by naturally stimulating the body's own endogenous synthesis of male pheromones. This means the resulting scent is uniquely personal to each individual wearer — an authentic olfactory signature rather than a one-size-fits-all fragrance.
The Sensfeel™ complex is built upon a powerful synergistic combination of two well-regarded natural extracts:
Together, these ingredients create a sophisticated active complex that works in harmony with your individual body chemistry, producing a scent profile that is entirely your own and naturally attractive to those around you.
More Than a Fragrance — A Confidence-Boosting Experience
Phiero Inside Out™ is crafted for the modern man who understands that confidence is one of the most compelling qualities a person can project. Regular use of this fragrance is designed to support a heightened sense of self-esteem and personal presence, helping you feel more assured and appealing in every interaction — whether at a professional networking event, a social gathering, or an intimate romantic encounter.
The fragrance itself has been carefully composed to complement the natural pheromone-enhancing effect, resulting in a refined, masculine scent that is both subtle and memorable. It layers well against the skin throughout the day, providing consistent, long-lasting wear that evolves with your body's natural warmth.

How to Use
Apply Phiero Inside Out™ to pulse points — such as the wrists, neck, and chest — as you would any eau de parfum or cologne. For best results, use consistently as part of your daily grooming routine to allow the Sensfeel™ active ingredient to support ongoing pheromone synthesis over time. Avoid contact with eyes and store away from direct sunlight and extreme heat to preserve the integrity of the formula.

Whether you are new to pheromone-based products or looking to upgrade from a standard fragrance, this innovative perfume offers a compelling, research-backed option worth exploring.
