Reviews
We created teenflo. to address the lack of transparency on the market.
❝ When my eldest daughter got her first period, I looked for menstrual panties: a comfortable, long-lasting alternative to disposable sanitary pads. Beyond leaks problems and the lack of small sizes, I was struck by the absence of legal information on their chemical composition. ❞
Ingrid - Founder, mum of (3) girls
FAQ
What is a menstrual panty?
Period underwear looks like regular underwear.
The fabric in the menstrual panties contains a moisture-wicking fabric. The fibers trap blood to keep it from leaking onto your clothes. The outer layer is finished with a liquid-repellent film🩸
The panties are washable and therefore reusable💦
On average, they retain their absorbent power for a period of 2 to 5 years. Our panties have an evolving design, very "stretchy" on the hips. They adapt to the evolution of your teen's body.
A sustainable alternative to classic period protections, to use as a replacement or complement 🌱
How to take care of period underwear?
Menstrual Panties are reusable periodic protections. Simply wash them after each use!
After rinsing them in cold water, put them in the washing machine with the rest of the laundry, ideally at 30°C.
To finish, leave them to dry, preferably in the open air.
(NB: You can use regular laundry detergent, without fabric softener or fabric softener. Bleach and detergents should be avoided.)

Why we don't use silver biocides.
Antibacterial agents based on silver particles are regularly introduced into menstrual panties in order to prevent the appearance of bad odors.
If these biocid agents are regulated and authorized for skin contact, the National Health Safety Agency of Food, Environment and Work (ANSES) warns of the risk of migration of these substances once dissolved in menstrual blood. The risk: a disruption of the vaginal flora.*
At TEENFLO, the well-being and health of our girls are at the heart of our approach. This is why we have chosen not to use these biocid agents.
Our panties incorporate Milktech PROTECT® technology: a patented absorbent complex based on casein with naturally antibacterial properties. These bio-sourced milk fibers are hypoallergenic. They absorb humidity and effectively fight against the proliferation of bacteria.
