What causes many small bumps along the jawline?

Under normal circumstances, the appearance of numerous small granules along the jawline may be caused by improper cleansing, excessive sebum production, closed comedones, ectopic sebaceous glands, or folliculitis. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a reputable hospital. Detailed analysis is as follows:

1. Improper Cleansing

Residual cosmetics or accumulated dust can clog jawline pores, preventing normal keratinization and leading to the formation of tiny granules. Cleanse twice daily with a gentle facial cleanser, thoroughly remove makeup using a dedicated makeup remover, and regularly exfoliate with a mild exfoliating product to clear away dead skin cells.

2. Excessive Sebum Production

Hormonal fluctuations or lack of sleep can increase sebaceous gland activity, causing excess oil to block pores and form small bumps. Maintain a regular sleep schedule and avoid staying up late, eat a light diet low in fried foods, use oil-control skincare products, and avoid frequently touching the jawline.

3. Closed Comedones

Abnormal keratinization of hair follicle openings blocks sebum from escaping, forming white or skin-colored small bumps that may develop into acne. Topical treatments such as adapalene gel, tretinoin cream, or oral isotretinoin may be used under medical guidance. Avoid squeezing the bumps and maintain proper hydration and sun protection.

4. Ectopic Sebaceous Glands

Sebaceous glands abnormally proliferate and cluster along the jawline, appearing as small yellowish or skin-colored granules without significant discomfort. Treatment options include cryotherapy under medical supervision or topical applications such as tazarotene gel or benzoyl peroxide gel. Minimize local irritation.

5. Folliculitis

Bacterial infection of hair follicles causes inflammatory red bumps, often accompanied by mild itching. Treatments may include mupirocin ointment, cefuroxime axetil tablets, or clindamycin gel, as prescribed by a doctor. Keep the jawline area clean and avoid friction or scratching.

In daily life, it's important to maintain proper skin cleansing and moisturizing; follow a regular sleep schedule to stabilize hormone levels; eat a balanced diet rich in fruits and vegetables; choose gentle skincare products; and avoid self-treatment of skin bumps to prevent infection and worsening symptoms.
