How to remove flat warts
Flat warts are caused by the human papillomavirus infection, commonly known as the HPV virus. This disease is highly contagious and recurrent; once it appears, it tends to grow on various parts of the body in most individuals. The most commonly used primary treatment method is laser removal of the warts, followed by the application of topical antiviral medications. This method is generally suitable for flat warts that are less numerous. Another method is wart vaccination therapy, which involves removing the flat warts and using them to create a vaccine that is implanted into the muscle of the patient, generating antibodies to fight against the flat warts. The last method involves the use of oral and topical medications, but this method is slower and requires long-term treatment. The treatment of flat warts also necessitates a long-term dietary avoidance of spicy and stimulating foods, increased physical exercise, and a stronger focus on immunotherapy.
Can acne scars heal by themselves?
Generally, scars formed from acne are impossible to heal naturally. Most acne scars are due to improper or untimely treatment, or scars formed from infection due to squeezing or scratching during the treatment process. These scars do not heal by themselves, and common topical medications are not particularly effective in repairing them. Generally, treatment is needed from a dermatology department in a formal hospital. If the scar is not particularly noticeable, fractional laser treatment can be used for repair. If there is significant hypertrophic scar tissue, local medication injections can be used for treatment, but they can't completely remove the scar, only temporarily shrink and soften it. Therefore, it is essential to follow proper treatment protocols during acne treatment to avoid scratching or squeezing and prevent scarring.
How to treat acne?
Acne is related to several factors including excessive secretion of sebum, consumption of spicy and stimulating foods, frequent staying up late, familial inheritance, and internal hormone levels. There are various treatment methods for this condition, which primarily depend on the individual's age. Treatment can be challenging during adolescence. If it is post-adolescence, treatment tends to be relatively easier. The most common treatment approach involves oral and topical anti-inflammatory medications, and it's effective to combine these with red and blue light therapy at a formal hospital for faster results. Traditional Chinese medicine facial masks can also be used to reduce local inflammation and decrease sebum secretion. However, acne tends to recur, particularly in adolescents. It is crucial for patients to avoid spicy and stimulating foods, not stay up late, and regularly exercise to reduce adverse hormone levels in the body. (Medications should be used under the guidance of a doctor based on specific circumstances.)
Does folliculitis require surgery?
Folliculitis generally does not require surgery, and can be completely cured by commonly used oral and topical anti-inflammatory drugs. If individual folliculitis is particularly prominent and has some pustules, you can disinfect the area locally, then use a needle to break them open and clean out the pus and blood. Unless the folliculitis is large, especially those on the scalp, and chronic medication is ineffective and gradually worsening, surgery might be required. You can go to the dermatology department of a regular hospital for surgery to completely clean out the pus and blood. To prevent recurrence of this disease, avoid spicy and irritating foods, do not stay up late, strengthen exercise, sweat more, and bathe more frequently.
Is athlete's foot contagious?
Athlete's foot is a disease caused by fungal infections and is highly contagious. Transmission can occur through contact with each other, sharing slippers haphazardly, or going to public baths and swimming pools. Once diagnosed, it is essential to receive formal treatment at a dermatology department in a reputable hospital. Antifungal creams should be applied twice daily for at least one to two months to completely eradicate the deep-seated fungi. Regularly soaking feet in hot water, and ensuring that worn socks and shoes are thoroughly sun-dried to disinfect them, can prevent cross-infection. Even after recovery from athlete's foot, it's important to avoid recurrence by maintaining good dietary and personal hygiene habits. It's advisable to avoid spicy food, refrain from staying up late, and use separate wash basins and bath towels from other family members.
How to remove acne marks?
Most acne patients, after undergoing standard treatment, tend to retain some acne marks on their faces. These marks generally do not require special treatment and will gradually fade or disappear over time. Alternatively, patients can opt for red and blue light therapy at hospitals, which can accelerate the fading of pigmentation. They can also visit a standard hospital to have cosmetic laser treatments to remove the marks, but these effects are not particularly fast and require long-term persistence. During the treatment period, it is essential to follow a standard diet and lifestyle practices. It is advisable to avoid spicy and irritating foods, and to prevent staying up late, feeling anxious or tense, or excessive sun exposure, as these factors may worsen the acne marks and increase the difficulty of treatment.
How to remove keloids?
The formation of keloids is largely related to one's inherent scarring constitution. Some patients are not prone to keloids but can still develop them due to particularly deep or large wounds. Additionally, keloids can form on the chest or shoulders after repeated occurrences of folliculitis. Currently, there are not many treatments for keloids. For larger keloids, medication can be used locally to gradually soften and reduce their size. For smaller areas, cosmetic surgical methods can be employed for removal, although this does not guarantee prevention of recurrence. Once keloids appear, they are mostly irreversible. If the keloid grows rapidly, treatment can also be sought at nuclear medicine departments, where nuclear radiation therapy is used.
Difference between Sebaceous Nevus and Flat Warts
Sebaceous nevus is primarily associated with localized epidermal growth and development, and is a type of benign hyperplasia. Most people are affected from birth or at a very young age, generally limited to one area and do not spread massively or contagiously across the body. Flat warts are caused by human papillomavirus (HPV) infections, which are contagious and recurrent, and can appear all over the body, not just in one area. Flat warts are generally dot-like or circular, whereas sebaceous nevi are mostly linear in growth, becoming larger and more proliferative over time. The most common treatment for sebaceous nevus is surgical removal, while flat warts can be selectively removed using laser treatment.
How to treat acne scars?
Acne is a disease caused by Propionibacterium acnes infection, with symptoms often more severe on the face. During the treatment of acne, if not handled properly or if the symptoms are severe, scars, pits, or post-acne marks may form after healing. Once these occur, there are no very effective medications available for treatment. It is possible to visit a dermatology department at a reputable hospital and use fractional laser treatment, which has decent effects. However, it may not be resolved in one session and could require many visits, and the costs can be high. Therefore, during the treatment of acne, it is crucial to follow a standard treatment regimen, avoid squeezing or picking at acne to prevent secondary infection, maintain a light diet, avoid spicy and irritating foods, and refrain from staying up late.
How is folliculitis considered cured?
After treatment for folliculitis, if the affected area feels completely flat when touched by hand, without any protruding or proliferative hard nodules, or red bumps, and lacks any pustule-like papules, it is generally considered to be healed. However, even though the condition has healed, it cannot be completely eradicated and there is still a risk of recurrence. It is crucial to avoid spicy and irritating foods long-term, try not to stay up late, engage in regular exercise, sweat more, bathe more frequently, and avoid soaking in public baths or swimming to reduce the possibility of bacterial infections. Also, avoid consuming spicy, greasy, or sweet foods as they can increase internal heat and dampness in the body, potentially exacerbating folliculitis. Therefore, once this condition occurs, it is essential to undergo standardized treatment.
