Curie is a deodorant brand that was featured on Shark Tank. It comes in a variety of scents, and the brand markets itself as a healthier alternative to traditional deodorant, claiming to contain "skin-loving ingredients," and "sustainable packaging."
But does Curie contain research-backed ingredients for odor-blocking? Is it really healthier than traditional deodorant? Which retailer sells it for the best price? And how do real users rate and describe the effects of Curie deodorant?
In this article we'll answer all of these questions and more, as we analyze the ingredients in Curie deodorant to give our take on whether or not the brand is likely to be effective for blocking odor, and whether or not it's healthy.
We'll pick the healthiest scent from the brand, feature real customer reviews, and provide a cost comparison to show which retailer sells Curie for the best price.
Ingredient Analysis
The ingredients in Curie deodorant are shown above.
Maranta Arundinacea root (arrowroot) powder is a natural deodorizer and a botanical alternative to talc that we consider much safer.
Sodium bicarbonate, better known as baking soda, is clinically shown to have anti-odor effects, although we can't find any trials showing it works as a deodorant.
Coconut oil has natural anti-bacterial and anti-fungal effects which makes it ideal for a deodorant formulation, as we discussed in our Lume Deodorant reviews article.
Fragrance used in deodorants was described as having negative effects to human health in a 2020 medical review.
Overall, we consider Curie deodorant somewhat likely to have odor-blocking effects. It contains some research-backed active ingredients, but we can't identify any ingredients clinically shown to have odor-blocking effects in a deodorant formulation.
For consumers interested in this brand, we strongly recommend the unscented (fragrance-free version) for health reasons.
We Tried Curie Ourselves
One of our product testers named Jodie Steinberg tried Curie deodorant for a month. Here's her experience:
The packaging is standard deodorant packing. I had no issues with it.
While the product was effective in masking unwanted odor, I found that it did not work as well as Lume.
It did not last as long, and the product itself did not have as strong of a scent as I would prefer. It was also not as soft on my skin as other aluminum-free deodorants I've tried.
The first few uses were a bit rough on my skin compared to other deodorants.
I would say the product lasts for a few hours, and then you would probably need to reapply, which may not be feasible if you are not at home.
I would also prefer a stronger scent.
Overall, I would rate Curie deodorant 6/10, and I do not plan on re-purchasing it.
