1. Dirty pillowcases and towels: Keeping your face on a pillow for hours with dirt and bacteria from dead skin cells can cause acne breakouts. Using a towel that is not regularly washed can also spread bacteria on your freshly washed face.

2. Over-cleansing with harsh products: Using strong cleansers, soaps, and alcohol-based toners can strip your skin of its natural oils, causing it to produce more oil, leading to acne breakouts. It is important to use gentle products and not over-cleanse your skin.

3. Dry skin: Skin that is dry can lead to a buildup of dead skin cells, clogged pores, and the growth of bacteria. To prevent acne breakouts, it is important to moisturize your skin regularly to maintain its natural balance.
