Small pinhole-like holes on the face may be caused by seborrheic dermatitis, folliculitis, acne and other diseases.
1. Seborrheic dermatitis: caused by bad dietary habits, microbial infections, heredity, immune dysfunction and other factors. It is characterized by excessive sebum secretion, flaking, vesicles, oozing, etc., causing patients to have enlarged pores and the symptom of pinhole-like holes on the face.
2. Folliculitis: Folliculitis may be induced by bacterial or fungal infections, decreased immunity of the body, and damage to hair follicles. Patients will have red papules centered on hair follicles, sometimes with pustules at the top, and repeated squeezing will leave concave and convex scarring. It manifests as small pinhole-like holes on the face.
3. Acne vulgaris: triggered by Propionibacterium acnes infection, poor dietary habits, increased sebaceous gland secretion and other factors. Pimples, papules, pustules, and cysts on the face, trunk, and other areas with dense sebaceous glands may cause pinholes on the face.
Patients with small pinhole-like holes in the face are advised to go to the hospital and identify the cause of the condition under the guidance of a doctor.
