FAQs

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.

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.

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 day or for up to 5 consecutive days. We recommend using only one suppository for every 24-hour period.

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.

With the use of The Killer® to help support a balanced vaginal environment, you can expect to experience a reduction in irritation which can often be associated with a vaginal 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 balance.

It's always best to consult with a doctor before use of any new product, particularly if you have sensitivity in your lower pelvis or abdomen, a sexually transmitted disease (STD), pelvic inflammatory disease (PID), vaginal bleeding, sores, ulcerations, nausea, fever, or chills. Stop use and contact a doctor if symptoms persist or worsen.

While both products are vaginal suppositories, they focus on different aspects of vaginal health. Flora Power® is designed to support and maintain a healthy pH, and The Killer® is designed to support healthy vaginal odor.

You can use The Killer® between 1 to 5 days to help support fresh odor, and you can use Flora Power® for as little as 1 to 5 days to help manage a healthy pH.

No— The Killer® is a vaginal suppository and is meant to only be inserted into the vagina. Do not insert The Killer into any other part of your body.

The Killer® is not vegan due to the gel capsule, but it is both gluten free and dairy free.

There are many different types of acids with ranging levels of pH (or potential of hydrogen, which is the measurement used to determine acidity). Many acids are “weak acids,” meaning they are safe to use. Common things in your house that contain weak acids are coffee, vinegar, and lemons.

Similarly, boric acid is a very weak acid and has many health and wellness uses, so don’t be scared by its name! The Killer® was formulated by a medical doctor and is manufactured with pharmaceutical-grade boric acid in our FDA registered facility according to CGMP standards – meaning, it’s safe to use as directed!

We recommend waiting until the end of your period (or almost the end) before beginning to use The Killer®️.

We recommend waiting 24-48 hours after using The Killer® before having sex.

Given that everyone is different and unique to their health, we recommend checking in with your doctor to make sure there are no interfering or contradicting ingredients between your birth control and The Killer®.

The Killer® is not approved for use if you are pregnant or breastfeeding. Please consult with your doctor to see which products may be most suitable for use while you are pregnant or breastfeeding.

For complete vaginal care, we recommend pairing The Killer® with:

If using The Killer® with Flora Power®, you'll want to complete use of The Killer® first, wait 1-2 days, then using Flora Power®.


As always, anytime you add anything new to your regimen, we recommend checking in with your doctor/healthcare provider to ensure it makes sense for you, and they can answer any more specific questions you might have!
