Because the chest is an area prone to seborrheic overflow, it can develop inflammatory lesions such as acne, and it is necessary to strengthen skin cleaning and provide anti-inflammatory symptomatic treatment. Oral medications such as clarithromycin sustained-release tablets and vitamin A acid ester capsules are recommended, while topical application of cloriodoquine cream or adapalene gel at the affected area can be supplemented with local treatments like red and blue light therapy and glycolic acid skin peeling. In daily life, it is important to bathe frequently, change undergarments regularly, and use selenium sulfide cleansers for skin cleaning. One should consume more green vegetables and dietary fiber, and avoid excessive spicy and high-calorie foods, including fried foods and sweets. For lesions on the chest, avoid squeezing to prevent scarring.

What is the white substance in acne?

The white substance in acne is mostly formed by the normal secretions of sebaceous glands accumulating at the mouth of hair follicles, combined with the fermentation of Propionibacterium acnes or Staphylococcus aureus, resulting in pus. Some of the white substances appear as tofu-dregs-like, which are pus formed after vigorous secretion of the sebaceous glands and then absorbed and dried. These substances can be treated with oral and topical anti-inflammatory medications. During treatment, it is also important to regulate one's diet and lifestyle habits, avoiding spicy and stimulating foods to reduce sebum secretion. It is also helpful to avoid staying up late, anxiety, and stress to alleviate symptoms or prevent recurrence.

How to reduce redness from rosacea

Rosacea mostly occurs in middle-aged people, more often in women, and can be accompanied by acne or seborrheic dermatitis. The most commonly seen type in clinical settings is erythematotelangiectatic rosacea, primarily appearing in the central parts of the face, especially on the nose, cheeks, forehead, and chin, with symmetrically occurring erythema. Different stimuli, such as environmental changes, temperature fluctuations, consuming hot beverages, alcohol, spicy foods, exercise, and bathing, can all cause persistent blushing and erythema, often accompanied by dry skin, a burning sensation, or a stinging feeling. To reduce erythema, it is first important to protect against the sun to avoid damage to the facial skin barrier by ultraviolet rays. It is also necessary to avoid excessive cleansing, enhance moisturizing and skin-nourishing treatments, and avoid extreme heat or cold, as well as the adverse stimulation of mental stress. Alcohol consumption and spicy or irritating foods should be avoided. Local cold compresses may be appropriate, and for severe and recurrent cases, internal administration of Chinese herbal medicine is recommended to clear heat, cool the blood, and reduce redness.

How to treat acne scar nodules

After complete recovery from acne, most people will form scars or some hypertrophic scar keloids. Generally, during the recovery phase of this condition, scratching or squeezing by hand is somewhat related. Currently, there are no highly effective drugs to completely heal these scars. The most common method is still to visit the dermatology department of a formal hospital and use fractional laser treatment, but the results vary from person to person and require many treatments. If the results are poor and the scar keloids are significantly hypertrophic, drug occlusion can also be used. However, drug occlusion cannot completely eliminate them; it can only make them shrink or become less noticeable. There is still a possibility that they might continue to grow.

What foods should not be eaten with acne?

Acne is a disease caused by the excessive secretion of sebum, consumption of spicy and irritating foods, frequent staying up late, and a combination of endocrine disorders. It involves infection of the skin surface by Propionibacterium acnes. Therefore, one should avoid spicy and irritating foods, such as chili peppers, lamb, seafood, and sweets. It is advisable not to misuse cosmetics, especially those that are greasy and likely to clog pores. Treatment should be standardized; one could visit a dermatology department at a reputable hospital for oral and topical anti-inflammatory medications. Red and blue light therapy can enhance the effects. Additionally, taking medications that regulate hormones can assist in the treatment. After recovery, it is crucial to maintain a disciplined diet and lifestyle habits.

Does acne spread through contagion?

Acne is caused by the infection of Propionibacterium acnes. This condition is related to factors such as excessive sebum secretion of the skin, frequent consumption of spicy, greasy, and sweet foods, as well as regular late nights, anxiety, and stress. The disease is not contagious; it does not spread through contact with others, nor through sharing towels or bath scrubs. Once diagnosed, it is crucial to seek proper treatment to prevent the condition from worsening and potentially leading to scars or pits on the face. Treatment can be sought at a reputable hospital's dermatology department, where oral medication combined with topical treatments, and supplemented by phototherapy with red and blue light, can be effective. After recovery, it is important to regulate one's diet and lifestyle, avoid spicy and irritating foods, minimize staying up late, engage in exercise, bathe more frequently, and sweat more.
