Bumps on both sides of the temples may be caused by acne, keratosis pilaris and other diseases. 1. Acne: If you often stay up late, often eat fatty and sugary foods or are affected by your parents’ genetics, or have a high level of androgens in your body, leading to excessive sebum secretion, acne is easily induced. Secondly, if the patient has abnormal keratinization of follicular sebaceous gland ducts, resulting in blockage of follicular sebaceous gland ducts and sebum discharge obstacles, it is also easy to induce acne, resulting in the growth of pimples on both sides of the temples. 2. Keratosis pilaris: genetic factors, vitamin deficiency, endocrine disorders and other reasons may trigger keratosis pilaris. Patients may therefore appear on both sides of the temples, usually no conscious symptoms, sometimes itchy. It is recommended to visit a hospital to find out the exact cause of the bumps on both sides of the temples.
