Why is there a closed mouth on the face?
Closed comedones (also known as closed comedones) are a skin problem that plagues many people, especially those with oily and combination skin. Closing the mouth not only affects the appearance, but may also further develop into inflammatory acne. So, why do closed lips appear on the face? This article will conduct a detailed analysis of the causes, influencing factors, and common misunderstandings, and provide structured data to help readers better understand.
1. Causes of closed mouth

Closure is mainly due to the blockage of the hair follicle opening, which prevents the normal discharge of sebum and forms tiny bulges on the skin surface. The following are common causes:
| Reason | Specific instructions |
|---|---|
| Excessive sebum secretion | Oily skin has active sebaceous glands, which can easily clog pores by secreting excess oil. |
| Abnormal keratin metabolism | The cuticle is too thick or does not fall off in time, causing the hair follicle opening to be blocked. |
| Improper use of skin care products | Skin care products or cosmetics that are too greasy may aggravate clogged pores. |
| eating habits | Excessive intake of sugar, oil, and dairy products may stimulate sebum secretion. |
| Incomplete cleaning | If makeup is not removed thoroughly or is not cleaned properly, the residue will clog the pores. |
2. Factors affecting the aggravation of shut-up
In addition to the above reasons, the following factors may make the silence problem more serious:
| factors | influence |
|---|---|
| stay up late | Lack of sleep affects skin repair and leads to imbalanced oil secretion. |
| pressure | Elevated stress hormones, such as cortisol, may stimulate sebaceous glands. |
| environmental pollution | Pollutants in the air can cling to the skin and worsen clogged pores. |
| excessive cleaning | Frequent use of strong cleansing products may damage the skin barrier and stimulate oil production. |

| Ignore sun protection | Ultraviolet rays can aggravate skin inflammation, so you should choose sunscreen products that are light and do not clog pores. |
