Why do pimples tend to grow around the mouth?

The main reasons for acne prone to develop around the mouth include: 1. Dietary habits: Consuming excessive spicy, greasy, or other irritating foods can stimulate sebum secretion, leading to clogged pores and consequently causing acne. 2. Poor local hygiene: Failure to clean the mouth area thoroughly after eating or following makeup removal may block pores, preventing sebum from being properly expelled and resulting in acne formation. 3. Hormonal imbalance: Long-term emotional suppression, irritability, stress, or insufficient sleep can lead to hormonal imbalances, increased androgen secretion, and stimulated sebaceous gland activity, which may also contribute to acne development. 4. Bacterial infection: When excess sebum is secreted, Propionibacterium acnes can easily proliferate, irritating the skin and causing acne. 5. Other factors: Improper skincare, medication effects, environmental factors, etc., may also lead to acne formation around the mouth.
