Best period underwear for teens: our picks and reviews

Disposable pads, tampons, menstrual discs, menstrual cups (or period cups), washable cloth pads—teens have plenty of options to manage their periods!

Disposable single-use protection, internal protection, washable protection, absorbent fabric protection—today, teens have options and that’s a good thing. So, why choose period underwear, and how do you find the best period underwear for teens?

• Easy to use. Unlike disposable products, period underwear is worn just like regular underwear. It’s that simple. You almost forget you’re on your period.
  
  
• Guaranteed discretion. Even though period underwear is very absorbent and can hold a lot, it doesn’t swell or show through. It stays very discreet or even invisible under clothing. Some models are even seamless so you can wear them completely unnoticed.
  
  
• A healthy and eco-friendly alternative. By choosing period underwear, you’re opting for a washable, durable, reusable menstrual product that’s more environmentally friendly. Period panties produce zero waste. They can be washed and reused for many years.
  
  
• Comfort and confidence. Well-designed, well-fitted, and thoughtfully made, period panties provide excellent support and absorb all flows efficiently, letting you experience your period stress-free!

Before you buy one or more pairs of menstrual underwear, there are several criteria to consider to make the best choice for a teen. What are they?

Period underwear comes in several levels of absorbency:

• Light menstrual flow. For those with a lighter period.
  
  
• Medium or normal menstrual flow. Perfect for regular, moderate flow.
  
  
• Heavy to very heavy menstrual flow. Designed to effectively handle significant bleeding, especially if you have a copper IUD or are in the postpartum period.

For example, the Mathilde panties from Louloucup are specially designed to handle very heavy or hemorrhagic flows. Their absorbency is equivalent to five tampons, making them an ideal choice for heavy days. The wearer stays dry. No soaking effect, no dampness, making for a very comfortable experience. 

Fit is essential for teens. It’s crucial to choose underwear that hugs their shape perfectly to provide optimal support and maximum comfort.

• Size guide. Every brand has a size guide. For Louloucup, the Mathilde underwear is available from XXS to XXXL, and the Lucie model is available from XXS (teen version, equivalent to size 34) up to XXL.
  
  
• Tailored fit. A higher waist, like Mathilde’s, offers a comforting, enveloping effect, while Lucie’s cut with flat seams guarantees invisibility under tight clothing. Each style has great features! 

The quality of materials and fabrics directly affects the comfort and effectiveness of period underwear. Here are some things to check:

• Organic cotton is the ideal natural material. Certified organic cotton feels soft and reduces the risk of irritation. Organic cotton is a must-have for period underwear!
  
  
• Polyamide makes the underwear durable and gives it the stretch it needs, while also making it easy to care for.
  
  
• The absorbent fabric sewn into the core of the underwear is dense and thick. The absorbent area should stay discreet while offering excellent retention.

Teen girls want to wear underwear that reflects who they are. That’s why design plays an important role:

• Careful finishing touches. The Lucie underwear, for example, features a subtle finish with gold details for a feminine, elegant touch.
  
  
• Variety of colors. Some panties, like Mathilde, are available in several colors (the Mathilde model in black for very heavy flow, and the Lily model in blue for medium flow) to suit everyone’s tastes.

To choose the best period underwear for teens, here are our three Loulou tips:

1. Choosing your size. It’s important to check the brand’s size guide, and if you’re unsure, don’t hesitate to go up a size for extra comfort.
2. Care. Regularly wash your underwear in cold water, avoid harsh detergents and fabric softeners, and do not tumble dry your menstrual lingerie to preserve the quality of the absorbent fabrics.
   
   
3. Try several models. Every body is different. It can be helpful to try out different styles to find the one that offers the best fit and optimal comfort right from the start.

To help with the challenge of first periods, Louloucup’s organic cotton period underwear is ideal. We’ve selected two of Louloucup’s top models for you, known for their effectiveness and comfort. 

The Mathilde menstrual underwear is designed to handle heavy and very heavy periods. With an absorbent fabric equivalent to five tampons, it’s especially suited for days with heavy flow. Its standout features include:

• An extended absorption zone that goes high in the front for optimal flow distribution.
• An elegant and discreet design: the underwear is black with a dotted mesh trim for a refined, stylish touch.
• Comfort and support: The high, full-coverage waist keeps everything in place, and the organic cotton lining is incredibly soft.

• Effectiveness. Ideal for heavy flow, it guarantees long-lasting protection.
• Versatility. Suitable for teens, but also great for postpartum use to manage lochia or to absorb light urinary leaks.
• Discretion. The design lets you wear it under any clothing without worrying about visible lines.

May be slightly thicker at the absorbent area, which is necessary to ensure its effectiveness, but might require a short adjustment period for first-time users.

The Lucie period underwear is Louloucup’s 2023 new release. It’s ideal for medium or light flows. It absorbs the equivalent of 2 to 3 tampons (about 20 ml), making it perfect for everyday use with total confidence. Its highlights include:

• Absolute comfort. Made from organic cotton (95% inside and out), it guarantees a soft feel and lets young girls and teens feel good all day long.
• Discreet design. With flat seams, this model is nearly invisible under clothing, even tight-fitting outfits.
• Careful finish. Fine gold details add a touch of femininity while remaining understated.

Designed for medium flow, it’s perfect for those with a regular period, providing just the right amount of protection. It’s also suitable for young girls with a light flow.

• Comfort and lightness. Its organic cotton design ensures optimal comfort and a natural feel, just like wearing regular underwear.
• Modern look. The playful, stylish design will appeal to teens looking to combine style and functionality.
  

For those with heavier flows, it’s better to choose a higher-absorption model, like Mathilde, to avoid any risk of leaks.

Several gynecologists and menstrual health specialists recommend using reusable period products, especially period underwear, for several reasons:

• Reduced irritation.
  Unlike disposable products (pads and tampons), organic cotton period underwear lowers the risk of irritation and allergies.
  
  
• Better hygiene.
  Period underwear offers better intimate hygiene.
  
  
• Positive ecological impact.
  By reducing waste production, washable period underwear for teens is part of an eco-friendly approach that benefits the planet’s health.

Feedback from people who have already tried this period underwear has been overwhelmingly positive. Here are a few testimonials from teen users or their moms:

“It’s for my daughter, who’s very sensitive and picky about her underwear. She finds it comfortable and feels at ease in it.” – Valérie S. 

“I ordered a set of 3 panties (Rebecca and Lucie) for my 13-year-old daughter. She uses 1 for the day and 1 for the night, she feels good in them, but she prefers the Lucie because the crotch is wider, so she feels more secure.” Véronique M.
