First periods too often go hand in hand with anxiety: leaks, odours, discomfort from conventional products… The first menstrual cycles should always be calm and comfortable. To achieve this, suitable period products are essential.


So between tampons, pads, cups, discs or period underwear, teens have plenty of options!


Today, let’s talk washable period lingerie and the best teen period underwear. How do you choose it well? Is it a good solution for a girl or teenager going through puberty? What about teen period panties in general, or heavy-flow period underwear for teens?


In this article, discover our practical guide to choosing the ideal style, combining 10‑hour leak protection, organic cotton comfort and a discreet design, to support teens through this transition smoothly.

Best teen menstrual panty: a revolution for her first period

A girl’s first period is an important milestone. It often raises questions: which protection should she choose? How can she stay comfortable at school, in PE or at night? How can she avoid leaks, odors or the discomfort of conventional products? It’s also a key moment for parents. How can they best support her? What advice should they give?


In recent years, the menstrual panty, or period brief, has emerged as a very appealing alternative.


This type of period protection is both modern and reassuring. Its durable, eco-friendly side is built to last. It’s also very reassuring: pretty, comfortable design and top-level absorbency.


Just like regular underwear, period panties hide discreet technology: a completely invisible absorbent zone sewn into the core of the panty. A washable absorbent panty is therefore a very reliable form of protection—on one condition, of course: choosing an absorbency level that matches your flow.

Made from GOTS-certified organic cotton, the hygienic brief guarantees optimal comfort (soft natural fabric, breathable) with no risk of allergies or irritation. In short, it’s genuinely healthy!


And finally, one last point: period panties are ideal for teenagers, allowing them to experience their period with complete peace of mind, in class, during sports or at night. Discover how this product is transforming the menstrual experience.

Simone, teens’ favourite period panty! 🩷


Our organic Simone period panties also come in a teen version! That’s already great news. In addition to the usual sizes from XS to XXL, you can now find them in XXS, i.e. age 12/14.


The great news is that you can now also get it in size 3XS, which corresponds to ages 10–12!

Simone is perfect for pre‑teens and teens experiencing their first period. It’s truly the favourite panty: soft, organic and ultra‑easy to wear for girls and young teens who have just started menstruating.

Why are period panties the best choice for teens?

Who said periods had to be stressful? Menstrual panties turn the experience into a calm, manageable time. No more tampons slipping or pads shifting. Discover Louloucup’s teen menstrual panties Mathilde, Liv and Lucie in XXS.

Absolute discretion

The organic cotton and their thickness of less than 3 mm guarantee absolute comfort, without a "diaper effect." They are invisible under tight clothing. A teenager can wear leggings or a light dress without worry.

For completely invisible, washable protection, try Liv or Lucie!

Leak-proof for up to 10 hours

Leaks are no longer a nightmare thanks to anti-odor and anti-leak technology. With 10 hours of protection, these teen products are reassuring even for heavy flows.

For top-level absorbency, try Mathilde (absorption capacity equivalent to 5 tampons!).

It’s simple and convenient

Using period underwear is not at all complicated, stressful, or anxiety-inducing. It’s actually a real advantage for teenage girls who don’t yet know their bodies or their periods very well. Period panties go on just like regular underwear. And that’s it!

It’s eco‑friendly and totally in tune with the times!

Eco-friendly, they replace hundreds of disposable products, drastically reducing our waste. Washable period underwear fits perfectly into a zero-waste, greener, more eco-conscious lifestyle that respects the environment. By washing them properly after use, you can keep them for many years (between 5 and 7 years), and avoid buying lots of polluting pads and tampons that can’t be recycled.

It’s healthy and safe for your body

With our organic period panties, you can finally say goodbye to questionable materials. No PFAS, no harmful substances, no petrochemical derivatives, etc. And because they’re an external protection, there’s no risk of TSS (Toxic Shock Syndrome).


Ready to say goodbye to leak anxiety? Discover Louloucup models in XXS. Made from organic cotton, they combine style, performance and durability. A solution designed for teenagers: softness, safety and freedom, even during sports.

How do you choose your first pair of period underwear?

Feeling lost? We’ll help you choose the best teen period underwear!

Criterion no. 1: absorbency level according to your flow

For teenagers whose flow can be unpredictable, panties designed for heavy flow offer optimal security. Louloucup’s XXS models (Mathilde, Liv, Lucie) feature triple-layer technology.


This odour‑ and moisture‑control structure allows for comfortable wear for up to 10 hours, even at school or during physical activities. For beginners, this capacity is reassuring and avoids the need for frequent changes.

For your information:

the Mathilde and Liv period panties have a capacity equivalent to 5 tampons (heavy or very heavy flow),

while Lucie has a capacity equivalent to 2–3 tampons (medium, normal flow).

Size: a key factor for comfort and effectiveness

Size XXS, designed for the slimmest pre-teens and teenagers (ages 10–12, hip measurement under 88 cm), fits young girls’ bodies perfectly.


Poor fit can cause leaks or discomfort, so follow the size guide. Once properly fitted, the panties stay discreet under clothing, avoiding any social awkwardness.

For example, the XXS Louloucup models are designed to fit curves without marking, even under tight-fitting outfits. It's really important to wear a menstrual panty that fits well, properly adjusted to your body so that it can absorb menstrual flow optimally.

Materials: prioritize softness and safety

Louloucup washable period panties are certified Standard 100 Oeko-Tex and lined with GOTS organic cotton. They combine comfort (cotton is a soft natural material) and safety (composition guaranteed free from harmful chemicals).


Did you know?

GOTS certification guarantees cotton grown without harmful pesticides and processed ethically.

The Oeko-Tex Standard 100 label guarantees the absence of irritating substances (nickel, formaldehyde, etc.), which is essential for sensitive skin.

Style: because that matters too!

Louloucup’s XXS styles (Mathilde, Liv, Lucie) combine absorbency, discretion and… style. It’s important to wear underwear we like, that looks good and makes us feel pretty!


Black or coloured, plain or printed, cotton or lace – go for underwear in a variety of styles! Liv is a seamless black period panty for a second‑skin effect, Mathilde has a timeless, elegant look, while Lucie features pretty, truly original gold details. The choice is yours!


A good cut boosts confidence—essential in adolescence—by combining practicality and elegance.

Practical guide: how to use and care for your period panties

The first use

Did you know that a simple wash before first use can boost the effectiveness of your period panties? To activate their absorbent properties, it’s best to machine‑wash them at 30°C or soak them in lukewarm water for 3 hours. Avoid hot water, which can damage the fibres. This pre‑wash removes any manufacturing residues and ensures optimal hygiene from the very first wear.

The 3-step washing guide

To keep your period underwear in perfect condition, follow these three essential steps:

Rinse with cold water: After use, run the period panty under cold water until the water runs clear. Hot water would set blood stains.

Machine wash: Place it in a laundry bag and use a cycle at a maximum of 30°C. Avoid fabric softener and bleach to preserve the materials.

Air dry: Hang them on a drying rack and avoid the tumble dryer. Heat can damage the waterproof layer.

How many pairs of period underwear do you need, and how long do they last?

Plan on having a stock of 3 to 5 period panties so you can rotate between washing and drying. It’s important to plan ahead and always have a clean pair ready. With proper care, they last 5 to 7 years. This makes them an economical and eco-friendly choice, cutting down on disposable waste. Opt for durable materials like organic cotton or Oeko-Tex certified fibers.

Experience your period with total confidence thanks to period underwear
