I. Seamless period underwear: guaranteed comfort and discretion
What is an invisible period panty?
A seamless period panty meets two specific user needs: optimal absorption and guaranteed discretion.
In other words, this type of underwear is designed to absorb your period and hug your curves without leaving marks, especially around the hips and buttocks. It really feels like a second skin. So you can totally wear period underwear even with tight, fitted, or body-hugging clothes.
This is a common concern when you choose to use period underwear: you’re always worried that the panties, boyshorts, or bloomers will be too thick or too visible under jeans or a dress. That’s a logical fear. If period underwear can hold all your flow all day or night, how can it possibly be invisible?
This is thanks to two very concrete qualities: a combination of ultra-absorbent technical fabrics that don’t shift or swell, and the lack of seams.
Result: you get very high absorbency (for the most effective models, up to 5 tampons’ worth) and incredible discretion. Suitable for light to heavy flows, the seamless period panty provides 12 hours of comfortable protection.
Perfectly discreet under your clothes.
The heat-sealed seams and ultra-thin fabrics chosen for this type of design make this product especially appealing.
You can easily wear these panties under skinny pants, tight jeans, fitted dresses, or even workout leggings without worrying about visible lines.
Your silhouette stays smooth. No folds, no bumps. You look perfect, confident, and protected!

"Love at first sight for the Liv model! With a heavy flow, I managed to wear it all day without leaks! Super comfortable, invisible under clothes because it’s seamless, and with a thinner absorbent area than other brands for the same flow—it totally does the job!" Jessica B. on Liv.

Seamless menstrual panty FAQ
How do you know if your period underwear is full?
To know if your period underwear is full, it’s important to understand your menstrual flow. Typically, a pair of period underwear can be worn for 8 to 12 hours for a light to moderate flow, and 4 to 6 hours for a heavier flow. If your flow is very heavy, feel free to combine your underwear with other products like a menstrual cup.
Pay attention to signs of discomfort like persistent dampness, unusual odors, or discomfort in your back or stomach. Set up a routine by keeping a journal of your cycle. This can help you anticipate the best time to change and enjoy your day without worry.
How long can you wear period underwear?
A period panty can generally be worn for up to 12 consecutive hours. You can wear it all day or all night, as long as you choose the right one for your flow.
For hygiene reasons, it’s not recommended to wear it for longer or for two days in a row without washing. Pay attention to signs that it might overflow, such as a feeling of dampness or leaks.
Wearing underwear for too long can lead to bacteria growth, causing irritation or disrupting your vaginal flora. To make changing easier during the day, bring a waterproof pouch with clean panties and wipes. Also, make sure to wash your period underwear thoroughly between uses for optimal hygiene.
Why does my period underwear smell bad after washing?
Unpleasant odors after washing may be due to insufficient washing, leaving blood residue. Wearing the underwear for too long, or using a pair not suited to your flow, can also lead to blood build-up and odor. Using harsh detergents or improper drying can also be factors.
To avoid these issues, rinse your underwear in cold water after each use and wash it by hand with a gentle soap or in the machine at a maximum of 86°F (30°C), using a mild, eco-friendly detergent. Avoid fabric softeners, bleach, and the dryer, and let your underwear air dry. If odors persist, consult a doctor to rule out a possible infection.
When should you throw away your period panties?
It's time to replace a period underwear when you notice a loss of absorbency, lingering odors despite thorough cleaning, or visible damage like holes or frayed seams. A high-quality pair typically lasts 5 to 7 years, but this depends on how often you use and care for them.
Signs you need to replace it include repeated leaks, a persistent unpleasant odor, or a loss of elasticity. Consider textile recycling or reusing as cleaning cloths before throwing it away. To extend its lifespan, rinse it in cold water after use, wash at a maximum of 86°F (30°C) without fabric softener, and air dry.
Is it possible to boil period underwear?
It is not recommended to boil period underwear. Hot water can set blood stains and damage the waterproof layers of the protective fabric. It’s best to wash them in cold or lukewarm water (no hotter than 86°F/30°C).
For proper care, rinse the panties in cold water after use, then wash them by hand or machine with a mild soap. Avoid detergents containing glycerin, fabric softener, bleach, or industrial stain removers. Air dry only—avoid the dryer or any direct heat source.
