Acne occurs when hair follicles clog up. Numerous factors can contribute to acne on the jawline, including genetics, certain conditions, and some medications.You may be able to treat jawline acne with over-the-counter medications. However, for more severe cases
1. Excess Sebum Production
• Sebaceous glands produce an oily substance called sebum, which helps lubricate and protect the skin. Overproduction of sebum can contribute to clogged pores.
2. Clogged Hair Follicles
• Dead skin cells can accumulate and mix with excess sebum, creating a plug in the hair follicle. This forms the foundation for acne.
3. Bacterial Growth
• A type of bacteria called Cutibacterium acnes (formerly Propionibacterium acnes) thrives in clogged pores, leading to inflammation and the formation of pimples.
4. Hormonal Changes
• Hormones like androgens (e.g., testosterone) can stimulate sebaceous glands, increasing sebum production. This is why acne is common during puberty, menstrual cycles, pregnancy, and other times of hormonal fluctuation.
5. Inflammation
• Inflammation occurs when the body reacts to clogged pores and bacterial growth, leading to red, swollen, and sometimes painful acne lesions.
6. Genetics
• A family history of acne can make you more prone to developing it, as genetics influence skin type, sebum production, and inflammatory response.
7. Diet
• Foods with a high glycemic index (like sugary snacks and refined carbs) and dairy products may trigger or worsen acne in some people.
8. Stress
• Stress doesn’t directly cause acne but can worsen it by triggering hormonal changes and inflammation.
9. Medications
• Certain drugs, such as corticosteroids, androgens, or lithium, can contribute to acne.
10. Cosmetic Products
• Using heavy, pore-clogging makeup or skincare products can lead to “cosmetic acne.”
11. Environmental Factors
• Pollution, humidity, and exposure to greasy environments can clog pores and irritate the skin.
