Bleach-like stain on underwear: what does it mean?

Vaginal pH, the discreet hero

The vagina has an incredible superpower: that of self-cleaning! Thanks to a natural secretion system and the presence of good bacteria (the famous lactobacilli), it regulates itself, naturally.

These secretions, which are slightly acidic, have a pH between 3.8 and 4.5. This level of acidity is completely normal, and it helps to maintain a healthy intimate environment, preventing the proliferation of bad bacteria.

Result? This acidity can have a slight bleaching effect on the fabrics, hence the famous little light marks on your panties. Nothing magical, just science… and a nice proof that your body works perfectly well.
