“This stuff is DANGEROUS”
hear me out, my ex hit me up 2 hours later saying he missed me. wtf.
why women choose sirense
a perfume that does the work for you.
four things it does once it’s on your skin.
-
boosts confidence
roll it on before you leave, and you'll walk into the room a little taller.
-
draws attention
the pheromones work below what anyone can smell. people hold eye contact a beat longer — and can't say why.
-
up to 12 hours of wear
oil-based, so it sinks into skin instead of evaporating off it. one morning pass is still there when the evening starts.
-
wears with anything
on its own, a soft skin-close vanilla. under your perfume, you won’t notice it at all — only they will.
real customers, real magnetism
what women like you are saying.
“unbelievable results”
skeptical at first, but after a week my confidence skyrocketed. people keep asking what's changed.
“i feel like a siren”
first date in months and i got asked for a second before the appetizers arrived. coincidence?
how it works
the part of attraction you can't see — but everyone feels.
attraction has a quieter layer underneath — chemical, instinctive, ancient. sirense bottles it, in three steps.

what's inside
three ingredients. nothing else.
we don't believe in 27-ingredient perfumes. sirense is three things in a 10ml oil base — and that's the whole list.
made in the USA with imported ingredients
the base
fractionated coconut oil
oil base — light, non-greasy, alcohol-free
the scent
vanilla essential oil
scent — warm, soft, skin-paired
the signal
copulins
molecules associated with human attraction signaling
- layers under any perfume
- blended & bottled in the USA
- vegan
- cruelty-free
- alcohol-free
- phthalate & paraben-free
the ritual
three seconds in the morning. all day in the room.
no spritzing, no learning curve. just one rollerball pass at the pulse points — and let your skin do the rest.
pulse points.
where skin runs warmest. where pheromones diffuse furthest.
- wrists
- neck
- behind the ears
- inner elbows
that's the whole ritual. the rest of the day takes care of itself.

how do pheromones work in humans?
pheromones are chemicals our bodies release through skin, sweat, and other secretions. they travel through the air, get picked up by other people's olfactory system, and influence how they perceive us — usually below conscious awareness.
so unlike perfume, which works on what people consciously smell, pheromones work on how people feel in your presence. copulins, the molecule in sirense, are among the most studied human pheromone compounds, associated with shifts in attraction, mood, and how warmly others read the wearer.
what does it smell like, and can i wear it with my perfume?
on its own, a soft, skin-close vanilla. copulins have a distinctive scent of their own, so for the first few seconds after you roll it on you may catch a brief hint of it. once the formula meets your skin it settles into warm vanilla, and that's what you and the people around you will smell.
under perfume you won't notice it at all: copulins work below the scent layer, so your fragrance sits cleanly on top.
what's in it, and is it safe for sensitive skin?
three ingredients: fractionated coconut oil, vanilla essential oil, and copulins. no alcohol, no parabens, no phthalates. it's vegan and cruelty-free — all three are plant-derived or synthesized, and we don't test on animals.
if you have particularly reactive skin, a patch test on the inside of your wrist is always a good idea.
how does the 30-day guarantee work?
every body chemistry is different. wear sirense daily for up to 30 days from the day your order arrives — if you don't feel the difference, write to us and we'll return every penny. no forms, no questions, no returns shipping. one email is enough, and you keep the bottle.
