FAQs

WHY WE MADE

THE KILLER®

Old-school solutions weren't cutting it, so we teamed up with experts in 2016 to bring you our incredibly popular boric acid suppository for fresh vaginal odor. The Killer® is formulated with just one powerful ingredient — boric acid. It provides fast support and, unlike other brands, is made without fragrance or essential oils.

What we're made of

The Killer® was developed to contain boric acid as its single ingredient — a safe and well-tolerated solution for controlling vaginal odor for over a century.

Boric acid

Boric acid is derived from a mineral found in seawater, and we source ours exclusively from France.

What we never include

Our vaginal suppositories are made without these all-too-common ingredients because we believe they belong nowhere near your wellness routine.

FRAGRANCE

What we don't include is what makes our life-changing formulas so trustworthy. We don't believe fragrance belongs inside your vagina or on your vulva (and most OB/GYNs don't recommend it either).

ESSENTIAL OILS

We don't believe essential oils belong inside your vagina or on your vulva (and most OB/GYNs don't recommend it either). We're obsessed with ingredient superiority for our products, and when it comes to your intimate health, essential oils don't make the cut.

GLYCERIN

Glycerin is a moisturizing agent found in many intimacy products. Research suggests glycerin may promote vaginal infections, so we never include it in our intimacy products.

SLS, SLES, and PEG

You deserve life-changing formulas that are trustworthy, modern, and safe. We don't believe the surfactants SLS, SLES, and PEG support your well-being, so we'll never include them in our intimate health products.

PARABENS

Parabens are preservatives found in many intimacy products. Some research suggests they could act like the hormone estrogen in the body, and some parabens are banned entirely from cosmetics in the EU. With this in mind, we choose to formulate paraben-free.

The Killer® vs. Them

Let us change your life

We know incorporating something new into your wellness routine is a major decision. We're here to give you confidence in your decision by sharing just how much our customer community loves our life-changing formulas.

    Helps with chronic ph issues

    This helps to balance my ph, doesn’t burn, and I can use for 7 days at night with no issues. However it did leave some slight residue internally which my gyno discovered. But other than that, so glad I restocked.

FAQs

What is The Killer® used for? What exactly is boric acid?

The Killer®, made of boric acid, is a vaginal suppository that promotes fresh vaginal odor.

Boric Acid is derived from a mineral found in seawater, and we source ours exclusively from France. Boric Acid is a safe and well-tolerated solution for controlling vaginal odor for over a century.

How do I use The Killer®?

The Killer® is a vaginal suppository — not a pill you take by mouth. We know it looks similar, but this will be inserted vaginally. 

To use: Wash your hands well to gently insert The Killer® with your fingers into your vagina. It should be inserted a comfortable amount, which should be far enough that it won't have the chance to slip out. There is no need to alter the capsule in any way. Just pop it in — that's it! Within a few hours, the capsule will start to dissolve and get to work.

Discharge is expected when using a vaginal suppository, so we recommend wearing a panty liner to help keep you clean.

What time of day should I use The Killer®? How long should I use it?

We recommend using it at bedtime so it can be one less thing you have to worry about during the day as it can cause discharge.

How long you use The Killer® depends on your body and your needs. You can use The Killer® for as little as 1-3 days or for as long as 7-14 days (an entire box). We recommend using only one suppository for every 24-hour period.

What’s the difference between The Killer® and Flora Power®? Can I use them together?

The Killer® and Flora Power® help support a healthy vaginal environment in different ways: 

The Killer® is a single ingredient boric acid suppository that promotes fresh vaginal odor.

Flora Power® is a probiotic + Vitamin C suppository for supporting healthy vaginal pH balance

Both are made without fragrance and essential oils. 

To use both The Killer® and Flora Power®, we recommend first using The Killer® for 1 to 14 days. Then a few days, after completing use of The Killer®, you can use Flora Power® for 1 to 5 days as needed to help support healthy vaginal pH balance.

How do I know if The Killer® is working?

With the use of The Killer® to help support a balanced vaginal environment, you can expect to experience a reduction in the itching and irritation which can often be associated with a yeast imbalance. Depending on your body and needs, you may see results in as little as one day or up to five days. Having a consistent regimen will be critical for managing a healthy vaginal yeast.
