II. Why should a teen choose period underwear?

Periods and multiple options

Tampons, pads, cups, washable pads, and even period underwear—today’s teens have options! And that’s a good thing! So with all these choices, which period product should you recommend to your teen?

The menstrual cup is a healthy, very hygienic, and economical internal protection. However, it may not be the most popular option for teens, as using a cup requires a certain comfort with your body.

The single-use disposable tampon is polluting, irritating, and its composition isn’t always clear or healthy.

The disposable pad is polluting. It can be bulky and isn’t very comfortable. Its composition isn’t always great. It’s practical, but not exactly pleasant to wear.

The menstrual brief, shorty, or high-waisted menstrual underwear can be worn all day or night without fear of leaks. Guaranteed discretion, guaranteed comfort—period underwear just needs proper care. Menstrual underwear makes starting periods easier. They offer an intuitive, easy solution that teens can handle with ease. These products eliminate the complexity of tampons and pads.

The benefits of period underwear for active teens

Special models for active teens fit perfectly with movement. These period panties offer complete freedom during sports or daily activities.

Styles for very heavy flow guarantee zero leaks, even during sports activities.

Models made from organic cotton (all Louloucup products are lined with organic cotton) provide softness, comfort, and breathability.

Period underwear is popular with teens because it looks just like regular underwear—no visible lines under clothes!

"This is my daughter’s favorite period underwear out of three different brands we tried. It’s the most comfortable and absorbent. She’s less fond of the color." Talitha bought the Simone model for her daughter.

User feedback confirms the reliability of Louloucup period underwear for heavy flows. Teenagers regain confidence and peace of mind in their athletic and social lives.

IV. How to choose the right heavy flow period panties for teens

To find the perfect style and size of underwear, several factors matter:

The intensity of your menstrual flow to choose the right absorbency level.

The teen’s body shape for a good fit.

Everyday activities. Does your teen do gymnastics? She’ll probably prefer a seamless style that stays invisible under her sports leggings.

Clean composition: prioritize organic cotton for better breathability and comfort.

Our advice: build a complete kit with 5 to 7 period panties to cover a full cycle. Mix and match different styles: daytime, nighttime, and for specific activities.
