It's not unusual for the skin on your face to go through changes during your lifetime. One such change that can develop is the appearance of small white bumps often described as "chicken skin." Although bumpy skin under the eyes is not usually a cause for concern, understanding the likely cause may help you find treatment and prevent them from developing in the future. One common cause of chicken skin under the eyes is milia, which are tiny, white bumps that frequently appear under the eyes and cheeks. Milia is caused by a buildup of keratin in the skin's pores, and although it's unclear what induces keratin buildup, you can do a few things to make the bumps less prominent and irritating. For example, moisturizing your skin with lotions and ointments, using humidifiers, and applying anti-inflammatory treatments can help reduce irritation, clear pores, and decrease bumps.
