Many women have noticed pale or faded patches on their underwear after washing and assumed it was caused by detergent or fabric damage. However, medical experts say the real explanation is completely natural and actually a sign of a healthy body.
According to an O. ᗸ-G.Y Ņ these light marks are caused by the natural acidity of discharge. The Female or.g αns maintains its health through a delicate balance of bacteria, mainly lactobacilli, which help keep its pH level slightly acidic — usually between 3.8 and 4.5. This acidity protects against harmful bacteria and infections, but it can also react with fabric dyes, gradually lightening the color of underwear.
Doctors emphasize that this bleaching effect is normal and not related to poor hygiene or laundry mistakes. In fact, it often shows that the body’s natural protective system is working properly. Darker fabrics tend to show the discoloration more clearly, while lighter materials may hide it. Cotton underwear may also display fading more than synthetic fabrics because it absorbs moisture more easily.
Experts note that not every woman experiences this effect, which is also normal. pH and discharge can vary from person to person depending on hormones, body chemistry, and fabric choices.
While discoloration itself is harmless, doctors advise paying attention to major changes in discharge. Healthy discharge is usually clear or slightly milky and should not have a strong odor. Symptoms such as itching, burning, unusual color, or a strong smell may signal infection and should be checked by a healthcare professional.
The discussion around this topic has helped reduce stigma and misinformation about female health. Many women have admitted they once felt embarrassed or confused by these marks, only to learn they are a natural sign of a healthy environment.
In simple terms, those faded spots are not damage or stains — they are evidence that the body is functioning exactly as it should, maintaining balance and protecting itself naturally.
