Cotton pads are an essential beauty product, yet many people are unaware that they have a shelf life. Expiration is primarily caused by environmental factors-such as exposure to air, light, and humidity-which lead to the breakdown or deterioration of the materials within the pads. Using expired cotton pads may irritate the skin, causing discomfort or even allergic reactions.
You can use unopened cotton pads even if they have expired, though it is advisable to check for signs of deterioration or unusual odors first. However, if the pads have deteriorated or the package has already been opened, they should not be used.
If you experience allergic reactions or other forms of discomfort while using cotton pads, stop using them immediately and seek medical attention. Some cotton pads contain chemical additives; if they expire or become contaminated, they can irritate or damage the skin.
