Some sanitary napkin brands on the market add fragrance (such as chemical fragrances) to cover up odors and enhance the user experience. However, sanitary napkins should be odorless under normal circumstances. If there is an odor, it may be a signal of bacterial growth and needs to be replaced in time. Experts point out that fragrance ingredients may cause allergies (such as an increase in the incidence of contact dermatitis by 15%-20%), private infection and other risks, and long-term use may affect the health of the reproductive system. It is recommended to choose unscented sanitary napkins and focus on the following parameters: material (preferably 100% cotton, the allergy rate of chemical synthetic materials is as high as 30%), breathability (breathability ≥800g/m²/24h can reduce the risk of bacterial growth by 50%), water absorption (≥10g/piece) and safety certification (such as FDA or ISO13485 certification).
