As we mentioned earlier, cotton is more prone to bacteria growth, which is the number one cause of acne breakouts. Not to mention that cotton is more prone to causing friction which is the second most common source of acne, especially on the back and body.
This means, sleeping on cotton will only encourage more acne unless you wash or swap out your sheets daily, but who wants to spend the time and money on that? No one.
Or you could simply switch your sheets to bamboo and save time on laundry, not having to wash or swap out your sheets as often and have clear acne-free skin again.
