Perfumes exist that purport to contain human pheromones. Manufacturers claim they will help you attract the opposite sex, sometimes charging $100 per bottle.
Of course, it’s never been proven that humans use pheromones to attract mates. It’s not even clear that human pheromones exist at all. But that doesn’t matter, because you buy a $100 bottle of pheromone perfume because it’s worth $120 to you to feel attractive to men.
It’s fine if you want to buy pheromone perfume, but know that the effect you’re getting is a placebo.
And perhaps know that you were attractive all along.
