How are period panties made?

  • The composition of the bottom is divided into layers of absorbent, waterproof, leak-proof and odor-proof fabrics
  • Period panties replace disposable tampons and pads, and the menstrual cup
  • All the blood is absorbed in the bottom of the panties, invisible under clothing.

How long to wear it?

Menstrual panties are made to last all day:

>> You put menstrual panties on in the morning, take them off in the evening, without risk of leakage or discomfort
>> Menstrual panties can be worn between 4 and 12 hours, to be adapted according to each person's flow (light, medium, heavy) and the time of the cycle
>> Period panties can be worn all day night if the model has enough coverage and the absorption zone from the bottom of the panties up towards the buttocks

Tip: it is quite possible to wear panties for light flow at the beginning of the cycle, at the time of ovulation in case of spotting* or as a hygienic protection for heavy vaginal discharge. The models of absorbent panties also called ''power'' will be pleasant to wear at night, in case of abundant flow or for sports sessions. These models often have a larger size absorbent fabric.

Editor's note : Spotting corresponds to slight blood loss between periods of menstruation, which often occurs at the time of ovulation.

Do period panties smell bad?

Tip: In case of persistent odors, consult a. e doctor (fungal infections and STDs can cause these inconveniences).
