Many people randomly touch their faces throughout the day — a hand on the cheek, a palm against the forehead, resting the chin on the back of the hand — but by doing so may inadvertently transfer bacteria and allergens from the fingers to the skin.
Dermatologist Dr. Ava Shamban, author of Heal Your Skin, told the Huffington Post that touching your face might not technically cause acne, but it could exacerbate or trigger it. This is because your hands contain oils that can lead to bacteria spreading to other pores, resulting in more pimples. Touching your face often can also make you more susceptible to catching a cold or a flu since your hands can come into contact with millions of germs.
