Why choose period panties?

Protect your health

Many people decide to turn to menstrual panties after discovering the dangerous compositions of tampons and disposable towels.

Indeed, various studies have revealed the presence of chemical compounds in disposable sanitary protection: carcinogens, endocrine disruptors, pesticides, hydrocarbons, etc.

The periodic protections being in direct contact with the mucous membranes, so it is important to make sure to use healthy and respectful products for your body. The buffers are implicated for several years in the onset of CST or Toxic Shock Syndrome, for example. 

To protect your health, periodic panties are therefore a great ally. Although the strain in question of toxic shock syndrome is present in only 1% of women, the prolonged use of internal period protection is a risk of bacterial development.

Prioritize comfort

At Louloucup, your comfort is our priority. The cuts of our period panties are particularly neat. Before the validation of the model and the production, all our panties are tried on different morphologies and in several sizes. The cut of the panties is not the same in XS or XL. Beyond the XL size, the models are modified and the size increased in order to offer a optimal comfort.

In addition, the inside of all our panties is entirely in certified organic cotton. Some styles of period panties are completely in cotton. Cotton is a natural and soft material to wear. It offers a comfort of use that does not give this “plastic layer” effect often felt when wearing a disposable protection.

Finally, menstrual panties represent a hygienic protection et Women really economical.

A woman lives about 35 years with her menstrual cycles. A menstrual cycle usually occurs every 28 days, or 13 times a year. Expenses related to disposable sanitary pads over a year are therefore important! It is estimated that a woman uses approximately 10 disposable sanitary pads in her lifetime.

Menstrual panties, although they constitute a significant budget to purchase, have a lifespan of 3 to 5 years. They generally pay for themselves in 5 to 10 cycles.
