What causes pimples on the forehead?

Generally speaking, "brain gate" refers to the forehead, and "pimples" refer to acne. Acne on the forehead may be caused by various factors such as diet, inadequate cleansing, seborrheic dermatitis, folliculitis, or eczema. When the above conditions occur, it is recommended to seek medical treatment promptly. Specific analyses are as follows:

1. Dietary Factors

Consuming excessive amounts of high-sugar, high-fat, spicy, or irritating foods can stimulate sebaceous glands to produce excess oil, leading to clogged pores and consequently causing forehead acne. It is important in daily life to adjust dietary habits and reduce intake of high-sugar and high-fat foods.

2. Improper Cleansing

Inadequate cleaning of the forehead allows residual oils, dirt, and cosmetics to accumulate and block pores, resulting in acne formation. Proper hygiene practices should be strengthened, including using facial cleansers suitable for one's skin type, regular exfoliation, and maintaining clear pores.

3. Seborrheic Dermatitis

Seborrheic dermatitis is usually caused by excessive sebum production or Malassezia infection. This condition may lead to acne-like skin lesions, causing the aforementioned symptoms, possibly accompanied by itching and flaking. Treatment under medical guidance may include antifungal agents such as ketoconazole shampoo, tacrolimus ointment, or pimecrolimus cream.

4. Folliculitis

Folliculitis can be triggered by infections such as Staphylococcus aureus or fungi. It causes inflammation around hair follicles, leading to acne-like lesions on the forehead, possibly accompanied by redness and pain. Treatment should follow medical advice and may include topical medications such as mupirocin ointment, erythromycin ointment, or clindamycin hydrochloride gel.

5. Eczema

Eczema may be related to allergies or environmental irritants. Scratching or secondary infection may result in acne-like lesions on the forehead, often accompanied by intense itching or weeping. Patients should follow medical advice and use medications such as hydrocortisone butyrate cream, mometasone furoate cream, or calamine lotion.

To prevent forehead acne and similar skin issues, it is important to maintain a balanced diet, keep the forehead clean, choose appropriate skincare products, and avoid excessive scratching of the skin.
