The shelf life of oil-absorbing paper is basically about 3 years.
Note:
Using oil-absorbing tissue too frequently, or using it in the wrong way and with the wrong intensity, is most likely to cause damage to the skin. Since the texture of oil-absorbing tissue is much more delicate than ordinary paper towels, the correct way to use oil-absorbing tissue is to press gently. Start with the T-shaped area where oil is most likely to come out, and then gradually move to the cheeks to remove excess oil. Similar to facial cleansing, oil-absorbing facial tissue only absorbs the oil floating on the epidermis when needed. Therefore, if you want to use oil-absorbing tissues, twice a day is the most appropriate frequency.
