Best Teen Period Underwear: A Revolution for Her First Period
A girl's first period is a major milestone. It often raises questions: What protection should I choose? How can I stay comfortable at school, during sports, or at night? How do I prevent leaks, odors, or the discomfort of traditional products? It’s also a key moment for parents. How can you best support her? What advice should you give?
The period panty has become a very popular alternative in recent years.
This sanitary protection is both a modern and reassuring solution. Its sustainable and eco-friendly qualities are built to last. It’s also very comforting: attractive and pleasant design, top-notch absorption.
Looking like regular underwear, period briefs feature discreet technology: an absolutely invisible absorbent layer sewn into the core of the panty. The washable absorbent panty is therefore a highly reliable option—as long as you choose the right absorbency for your flow.
Made from GOTS-certified organic cotton, the period underwear guarantees optimal comfort (natural softness, breathability) with no risk of allergies or irritation. In short, it’s truly healthy!
Finally, another key feature: the period panty is perfect for teens, letting them experience their periods with peace of mind—at school, during sports, or overnight. Discover how this product is changing the menstrual experience.
Why are period panties the best choice for teens?
Who said periods have to be stressful? Period underwear turns the experience into a calm moment. No more slipping tampons or pads shifting out of place. Check out Louloucup’s teen period underwear in Mathilde, Liv, and Lucie models, available in XXS.
Total discretion
The organic cotton and their less-than-3mm thickness guarantee absolute comfort, with no "diaper effect." They're invisible under tight clothing. A teen can wear leggings or a light dress with confidence.
For washable, completely invisible protection, try Liv or Lucie!
10-hour leak protection
Leaks are no longer a nightmare thanks to odor-control and leak-proof technology. With 10 hours of protection, these teen-friendly products offer peace of mind even with heavy flows.
For top absorption, try Mathilde (holds as much as 5 tampons!)
It’s simple and practical.
Using a period underwear is simple, stress-free, and worry-free. It's a real advantage for teens who are still getting to know their bodies and their periods. Period panties are worn just like regular underwear. That's it!
It's eco-friendly and totally in right now!
Eco-friendly, they replace hundreds of disposable products, drastically reducing our waste. Washable period underwear is fully in line with a zero-waste, greener, more eco-friendly, and environmentally respectful approach. By washing them properly after use, you can keep them for many years (between 5 to 7 years) and avoid buying lots of polluting pads and tampons that can’t be recycled.
It’s healthy and safe for you
With organic period panties, you can say goodbye to questionable ingredients. No PFAS, no harmful substances, no petrochemical derivatives, etc. Plus, since it’s an external protection, there’s no risk of TSS (Toxic Shock Syndrome).

The #1 criterion: absorption level according to your flow
For teens whose flow can be unpredictable, underwear designed for heavy periods offers optimal protection. Louloucup’s XXS models (Mathilde, Liv, Lucie) feature triple-layer technology.
This odor- and moisture-resistant design allows for comfortable wear for up to 10 hours, even at school or during physical activities. For beginners, this capacity offers reassurance without the need for frequent changes.
For your information:
whereas Lucie holds the equivalent of 2 to 3 tampons (for medium or normal flow).
Size: a key element for comfort and effectiveness
The XXS size, designed for younger pre-teens and teens with a petite frame (ages 10–12, hip size under 88 cm), perfectly fits the shape of young girls.
A poor fit can cause leaks or discomfort, so follow the size guide. Once it fits right, the underwear stays invisible under clothes, so there’s no social awkwardness.
For example, Louloucup’s XXS models are designed to hug your curves without leaving marks, even under tight clothing. It’s really important to wear period underwear in your size, properly fitted to your body so it can absorb menstrual flow optimally.

GOTS certification guarantees cotton grown without harmful pesticides, following ethical processes.
The Oeko-Tex Standard 100 certification 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 you love—ones that are beautiful and make you feel good!

Practical guide: how to use and care for your period underwear?
The first use
Did you know that a simple wash before first use can boost your period underwear’s effectiveness? To activate its absorbent properties, it’s recommended to machine wash at 86°F (30°C) or soak in warm water for 3 hours. Avoid hot water, as it can damage the fibers. This prewash removes 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, rinse your period underwear in 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 no more than 86°F (30°C). Avoid fabric softener and bleach to preserve the materials.
Air dry: Use a drying rack and avoid the dryer. Heat can damage waterproofing.
How many pairs of period underwear do you need, and how long do they last?
Make sure you have a supply of 3 to 5 pairs of period underwear so you can alternate between washing and drying. It’s important to plan ahead and always have an extra pair on hand. With proper care, they can last 5 to 7 years, making them an economical and eco-friendly choice that reduces disposable waste. Opt for durable materials like organic cotton or Oeko-Tex certified fibers.
