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 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 should I do if I have acne on my chest?

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.

How to treat acne scar bumps?

Acne scars and keloids are often caused by improper treatment of acne or by scratching, squeezing, and breaking the skin during the treatment process, leading to infection and the subsequent formation of these scars and keloids. Once formed, it is impossible to completely remove them. If the keloid scars are not particularly prominent, you can visit a dermatology department at a standard hospital to repair them with fractional laser treatment. If the keloid scars are very noticeable and proliferative, you can also visit a dermatology department at a standard hospital for drug injection treatment, but it is not possible to completely remove them, only to temporarily relieve the symptoms. If the scars are relatively small, cosmetic surgery to excise them can be an option. Therefore, during the treatment of acne, it is crucial to follow standard practices and timely treatment, and to avoid scratching or squeezing the skin to prevent the formation of keloid scars.

How to remove acne scar bumps

Acne is somewhat related to the vigorous secretion of one's own sebaceous glands. During the treatment process, most people either treat improperly or frequently pick and squeeze their acne, which can lead to scars that are troublesome to treat if broken. If the scar proliferation is not too pronounced and relatively flat, one can visit a reputable hospital's dermatology department for fractional laser treatment. If the scar proliferation is more obvious and raised, medical interventions at a hospital may be necessary, typically involving two to three injections. This can generally soften, flatten, and shrink the scar slightly, but it is impossible to completely remove it. This condition is also somewhat related to individual constitution. During treatment, one should maintain proper dietary and lifestyle habits. During the acne treatment period, try not to pick, squeeze, or scratch the acne to prevent scars from forming.

Is it effective to use toothpaste on acne?

Acne is related to excessive sebum secretion, consumption of spicy and irritating foods, or frequent staying up late. Generally, it is a disease caused by Propionibacterium acnes infection. Commonly used toothpaste applied externally is ineffective as it cannot remove the Propionibacterium acnes on the acne surface. Once identified, it is still necessary to seek formal treatment at the dermatology department of regular hospitals. Oral medications combined with external use and phototherapy treatments such as red and blue light can improve the condition more quickly. After recovery, it is crucial to avoid spicy and irritating foods long-term, try not to stay up late, avoid anxiety and stress, and refrain from improperly using cosmetics that can clog pores. Regularizing diet, lifestyle habits, and enhancing exercise can help prevent recurrence significantly.
