Menstrual cup or period panties: which should you choose?

Pads, tampons, panty liners, washable pads, menstrual discs, and now period underwear and menstrual cups—women and teens today have lots of options to stay comfortable during their periods! 

This time of the month and the menstrual cycle, often feared and dreaded, is undergoing a real revolution! Indeed, with the arrival of durable and washable period products on the market, the game has changed!  

Women and girls can now invest in quality menstrual products that they can reuse again and again, cycle after cycle. This is great news for both their wallets and the planet!  

But which model to choose? Cup or menstrual panties? Cup or absorbent underwear? What is the best cup, what is the best menstrual panty? Between ecological innovations and ultimate comfort, the question arises: menstrual cup or menstrual panties? Choosing and finding the right period protection that suits your personal needs and expectations is important. Today, with this comparative guide, you’ll find all the necessary information about our two flagship products at Louloucup: the panties and the cup.

Menstrual cups have made a strong comeback in recent years. Yet this feminine, intimate protection has been around for a long time. Practical, reliable, and comfortable, the cup has plenty of advantages!

The menstrual cup, also known as a “cup,” is an internal menstrual protection. Designed to be inserted into the vagina, it collects menstrual blood without exposing it to air. This small, bell-shaped device is made of medical-grade silicone, is flexible, and folds for easy insertion. Once in place, it stays put and you won’t even feel it. 

At Louloucup, two models are available: the classic pink menstrual cup and the soft turquoise menstrual cup. Each model comes in two sizes (small and medium) to suit everyone’s needs, from young girls who are still virgins to more experienced women who have given birth vaginally, for example.

A menstrual cup works in a very simple way: after being sterilised (either in a steriliser or in boiling water for 5 minutes), it’s inserted into the vagina.

Once in place, its unique, patented shape creates a natural seal that prevents leaks while collecting menstrual blood discreetly and hygienically. This solution offers effective protection for all your daily activities – even swimming!

You empty and rinse your cup roughly every 6 hours. At the end of your period, remember to clean it thoroughly, sterilise it and store it in a pouch away from dust. 

By choosing a menstrual cup, you can say goodbye to disposable tampons and pads that generate a lot of non-recyclable, polluting waste. Made from high-quality medical-grade silicone, the cup is reusable for several years, making it an eco-friendly solution. In short, it’s a great investment! 


Once properly positioned, the menstrual cup is unnoticeable. It offers complete discretion, especially for those who want to play sports or swim without worrying about their protection. Whether under tight sports leggings or a swimsuit, no one can tell you’re wearing a cup! 


Suitable for both normal and heavy flows, the Louloucup menstrual cup has a generous reservoir. So even on your heaviest days, you’re well protected for long hours at a stretch.


Inserting and removing the cup can be a challenge for some, especially at first. It takes some time to get used to the technique and find the right position to prevent leaks or discomfort.

For safety reasons (especially to avoid toxic shock syndrome), it’s recommended not to wear a cup for more than 6 hours at a time, which limits its use overnight. For a peaceful night’s sleep, other options like period underwear can be considered.


Some women may feel initial discomfort due to their anatomy. It’s important to take the time to find the model and size that work best for you.

You absolutely can’t tell a regular panty from a period panty. But washable underwear has a real advantage: inside the lining, there’s an ultra-absorbent membrane sewn in. This dense, high-tech fabric captures menstrual flow extremely efficiently. It’s like having a super sanitary pad sewn right into your underwear.

The period underwear is an incredibly practical hygiene product. It’s worn during your period, but that’s not all. Many women use period panties to catch vaginal discharge, light bladder leaks, or even postpartum to absorb lochia. 
Period lingerie comes in a wide variety of styles and cuts to suit everyone: briefs, boxers, tangas, thongs, high-waisted panties, boyshorts, and more. 

Unlike the cup, period underwear is used just like any other underwear. No complicated learning curve: just wear it and change it as needed.


Period underwear offers effective protection without the need for any adjustments during the day. You don’t have to worry about inserting or removing anything, making it an ideal solution for daily use or long outings.


It’s perfect for active women, teens, and even those who play sports. For women with a moderate flow, it lets you enjoy your day to the fullest without compromising on comfort or safety.


Just like menstrual cups, period underwear helps reduce waste from disposable products. It’s part of a zero-waste, sustainable approach.


The purchase price of period underwear can be higher than that of a cup. Plus, to cover a full cycle, you often need several pairs, which can mean a significant initial investment. At Louloucup, we recommend starting with five pairs of period underwear. Our custom bundle with a sliding scale price is perfect for beginners. 


To maintain their effectiveness, period panties need to be washed by hand or machine according to specific instructions. Regular care is essential to ensure their durability and hygiene.


Period underwear can be an ideal option since it doesn’t require complicated internal handling. You can go through your period with peace of mind from the start, without the stress of insertion.


The menstrual cup offers unmatched discretion and freedom of movement. It’s especially popular for swimming and sports thanks to its capacity and comfort when properly positioned.


If you’re looking for protection for sleeping or for long, uninterrupted days, period underwear is probably your best option. Its simple use and moisture-wicking ability make it the ideal ally for nighttime.


Both cups and period underwear have their benefits. The menstrual cup, thanks to its large reservoir, is perfect for heavy flows, while some heavy flow period underwear also offer effective protection. You can even choose a combo pack to enjoy the advantages of both!

Louloucup is, above all, the story of a close-knit mother-daughter duo who decided to reinvent period protection. Their goal? To offer healthy, stylish, and eco-friendly alternatives to the traditional products found in supermarkets. 

Louloucup started out by:

• by launching ultra-comfortable menstrual cups;
•  then expanded its range with menstrual lingerie, including panties specially designed to hold menstrual flow;
• Today, Louloucup has continued the adventure by offering its users period swimsuits, 
• but also shapewear that’s extra supportive yet comfortable. 

At Louloucup, the idea is simple: to offer women reliable period protection that’s gentle on their bodies and the environment.

After this long comparison between the two types of washable and reusable period protection, our best advice is to trust your instincts, test things out, be patient with yourself and your body, and have confidence! 

It’s really important to find reliable period protection you can trust. Beyond your flow, comfort, and absorbency, the question and choice of the right hygiene solution is very personal and mostly comes down to feelings. The wisest choice will depend on your lifestyle, your flow, and your personal preferences.

Cup or menstrual panties, in both cases, you’ll revolutionize your relationship with your period and shake up your menstrual routine with these types of menstrual products. In a good way, we assure you! 

Better ingredients, savings, comfort – the benefits are many. The choice between a menstrual cup and period panties depends 

• personal preferences, 
• on the type of flow (its intensity and nature)
• and also on your lifestyle.

What if you didn’t have to choose? What if you got both types of protection so you could switch between them and wear whichever one you want, depending on your mood or needs?

Why not wear a cup during the day and period underwear at night? Or, for those who are more anxious about leaks, why not wear both a cup and period underwear?

The best advice is to try both options. Many women choose to alternate: a cup for when they want discretion and freedom, and period underwear for days when comfort and simplicity are key.
