Chin pimples are a common issue, often triggered by a mix of hormones, habits, and skincare routines. Here’s a breakdown of the top causes:
The most frequent cause of chin and jawline acne—especially in adults—is hormonal changes. This includes shifts during the menstrual cycle, pregnancy, or starting/stopping birth control.
Stress increases cortisol, a hormone that can lead to increased oil production and clogged pores, particularly around the chin and lower face.
Certain foods—like dairy, sugary snacks, and processed carbs—may trigger breakouts in some people. High glycemic diets are especially linked to acne flare-ups.
