According to Livestrong - a site that provides reliable information about health, nutrition and fitness in the US, when using a face mask, we are not only washing away dirt and excess oil on the skin but also washing away old skin cells.
In addition, the humidity and temperature in the bathroom will also create conditions for bacteria to grow on towels. Therefore, if you do not wash your towel every day, it will cause your face to encounter conditions such as:
Causes skin irritation
When you use a towel that accumulates a lot of dirt, oil and bacteria, the possibility of causing your skin to become irritated will increase, especially for people with sensitive skin or those with skin diseases such as eczema and psoriasis.
Can cause skin infections
If you use a towel that is not washed when the skin is injured, bacteria accumulating on the towel will enter the wound, which can get you infected.
A small infection can become more serious, such as a staphylococcal infection. To avoid this situation, you need to wash your towel regularly and always use a clean towel to dry your face.
Can cause allergies
Bacteria growing on towels can lead to the growth of mold, which will cause many types of allergies such as nasal congestion, sneezing, rashes, and fatigue.
To prevent this from happening, wash your towel thoroughly after each use, dry it and replace it periodically.
