Dealing with acne on the face requires a scientific approach based on its causes and severity. Firstly, adjust lifestyle habits: avoid staying up late, ensure 7-8 hours of sleep daily to reduce excessive sebum secretion; follow a low-sugar, low-fat diet, consume more fresh fruits and vegetables, and avoid spicy or high-sugar foods (such as milk tea and cake) that may exacerbate inflammation.

In terms of skin cleansing, choose a gentle amino acid-based facial cleanser and wash the face twice daily, avoiding excessive cleansing that may damage the skin barrier. If acne primarily presents as comedones, topical retinoid creams (such as adapalene) can be applied locally to promote skin exfoliation. For red, inflamed papules, benzoyl peroxide gel or antibiotic ointments (such as clindamycin) may be used.

In addition, avoid squeezing pimples manually to prevent infection spread or scarring. Products containing salicylic acid or fruit acid can be used once or twice weekly to help unclog pores, although caution is advised for sensitive skin. It is recommended to seek timely medical advice, allowing a professional dermatologist to develop an individualized treatment plan based on the type of skin lesions, thus avoiding self-medication that could worsen the condition.

Thickening and yellowing of the toenails are commonly seen in onychomycosis (commonly known as ringworm of the nail), a condition caused by dermatophytes, yeasts, and non-dermatophyte molds.

Hypertrophic nail conditions or hyperkeratotic nail diseases may also lead to thickening and yellowing of the nails. Genetic factors, such as mutations in inherited genes, can also cause nail thickening. Poor lifestyle habits, such as prolonged barefoot labor or activities, or nutritional deficiencies caused by an unbalanced diet and picky eating, may also result in nail thickening and yellowing.

Long-term wearing of ill-fitting shoes, pressure and friction on the toes, or subungual hemorrhage due to trauma, if not properly managed, can similarly lead to changes in nail color and texture. Skin conditions such as psoriasis and eczma, when involving the toenails, can affect the normal function of the nail matrix, leading to nail abnormalities.

In terms of treatment, in addition to topical antifungal medications, severe cases may require oral antifungal drugs or even surgical nail removal. At the same time, maintaining clean and dry feet, choosing breathable shoes and socks, and avoiding walking barefoot in public areas can effectively prevent onychomycosis.

If any physical discomfort symptoms occur, it is recommended to visit a hospital promptly and follow medical advice for appropriate management.

Whether patients with pancreatitis can drink tea needs to be analyzed according to the stage of their condition. Drinking tea is not recommended during acute episodes of pancreatitis; however, moderate tea consumption may be acceptable during the recovery phase. Detailed explanations are as follows:

From the perspective of disease analysis, during the acute phase of pancreatitis, patients must strictly fast (both food and water) to allow the pancreas to rest fully. Drinking tea during this period may stimulate gastrointestinal motility and promote pancreatic secretion of digestive enzymes, thereby increasing the burden on the pancreas. Thus, tea consumption is strictly prohibited.

Once the condition improves and the patient enters the recovery phase, small amounts of weak tea may be consumed. This is because components in tea such as polyphenols have antioxidant properties that may aid recovery to some extent. However, strong tea contains high levels of caffeine and theophylline, which may stimulate the nervous system and gastric acid secretion, potentially triggering a recurrence of pancreatitis.

During the recovery period, weak green tea or weak black tea may be selected, with each serving not exceeding 200 ml. Tea should not be consumed on an empty stomach or before bedtime. In daily life, patients should follow a low-fat, bland diet, consume more fruits, vegetables, and whole grains rich in dietary fiber, and avoid greasy, spicy, or irritating foods. Furthermore, alcohol consumption must be strictly avoided, regular作息 (作息 should be translated as "作息" means rest and activity patterns) lifestyle habits should be maintained, overeating should be avoided, and regular follow-up tests of serum amylase and lipase levels are necessary to adjust diet and lifestyle based on recovery progress.

Washing your face frequently is not always beneficial. In fact, excessive cleansing can disrupt the skin's natural barrier and oil balance, leading to dryness, irritation, or sensitivity.

Maintaining facial cleanliness is important for preventing skin issues such as acne and pimples. However, overwashing may strip the skin of necessary oils that are essential for maintaining moisture and barrier function.

Everyone's skin type and needs are different. For oily skin, more frequent cleansing may be needed to reduce oil buildup; for dry skin, excessive face washing may worsen dryness and tightness. Moisturizer should be applied promptly after washing to lock in moisture and maintain skin hydration.

Environmental factors should also be considered: if you are in a dusty environment, exposed to heavy cooking fumes, or sweat heavily, it may be appropriate to rinse your face with water, although facial cleanser is not needed every time; in a relatively clean home environment, excessive face washing may not be necessary.

The key to facial cleansing lies in "moderate cleansing." If skin problems (such as dryness, acne, sensitivity) occur frequently, it is advisable to consult a dermatologist.

Diabetes may lead to skin ulcers. A prolonged state of high blood sugar can affect circulation and nerve function, leading to insufficient blood supply to the skin tissue and a decreased capacity for repair. In addition, diabetes weakens the immune system, increasing the risk of infection. When the skin sustains minor injuries, wounds heal slowly due to these factors and may easily develop into ulcers or even severe skin breakdown. Therefore, diabetic patients need to pay special attention to skin care in order to prevent the worsening of skin problems.

To prevent and manage skin ulcers caused by diabetes, it is recommended to maintain good blood sugar control, follow the treatment plan provided by your physician, and regularly monitor blood glucose levels. Keep the skin clean and dry, especially in areas prone to sweating, such as between the toes. Choose appropriate footwear to avoid friction and pressure on the skin. If skin damage or abnormalities are detected, clean the area promptly and apply suitable antiseptic ointment. Seek medical attention when necessary, as a doctor may prescribe antibiotics or other medications to control infection and promote healing. Regular skin examinations to detect and address potential issues early can effectively reduce the risk of skin ulcers.

Iodophor can be used to disinfect damaged skin. Iodophor is a broad-spectrum antimicrobial agent with effective bactericidal properties, capable of killing various microorganisms including bacteria, viruses, and fungi. Compared to tincture of iodine, iodophor is less irritating and does not cause significant pain. Therefore, iodophor is suitable for treating minor skin injuries such as abrasions and cuts, effectively preventing infection.

When using iodophor to treat damaged skin, it is important to ensure the surrounding skin is clean. Gently rinse away any dirt with clean water. Then apply an appropriate amount of iodophor onto the wound surface using a cotton swab or gauze, taking care not to rub vigorously, which may worsen the injury. If the wound is deep or contains foreign material, it is recommended to seek medical attention before applying iodophor for disinfection. After applying iodophor, cover the wound with a sterile gauze dressing to maintain cleanliness. If signs of infection such as redness, swelling, or pus discharge appear, seek medical advice promptly for further treatment. Iodophor is a safe and effective disinfectant suitable for most cases of minor skin injuries.

When dealing with facial acne caused by endocrine disorders, treatment should address three aspects: regulating the endocrine system, localized treatment, and lifestyle improvements.

Endocrine imbalances should be evaluated by a qualified physician and may involve hormone level testing. Based on the results, treatment plans may include oral contraceptives to regulate hormonal balance or anti-androgen medications. Local treatments involve topical creams containing benzoyl peroxide, benzocaine, or antibiotics to reduce inflammation and eliminate acne-causing bacteria.

Diet should primarily consist of bland, easily digestible foods, avoiding spicy foods such as hot strips, spicy powder, and hot pot. Eat more fresh fruits and vegetables, such as cucumber, pineapple, apples, and white radish, which are rich in vitamins and fiber and help improve skin condition.

Ensure adequate sleep and avoid staying up late, as this helps alleviate endocrine disorders. Establish regular lifestyle habits that promote skin health. Maintain facial hygiene by using mild, non-irritating facial cleansers to thoroughly clean the face and prevent oil from clogging pores.

Treatment requires patience, regular follow-up visits, and following medical advice to adjust the treatment plan for optimal results.

Small red bumps appearing on the arms may be caused by various factors, such as allergic reactions, skin inflammation, infections, or contact dermatitis.

Contact dermatitis is caused by exposure to allergenic substances, resulting in localized red papules accompanied by itching. At this time, contact with the allergen should be avoided, and antiallergic medications such as loratadine tablets should be taken orally as directed by a physician. Applying cold water or an ice pack wrapped in a towel gently to the affected area can help reduce swelling and itching. Keeping the skin clean and dry, wearing loose and breathable clothing, and avoiding friction or scratching the affected area are also recommended.

Eczema is an allergic skin disease characterized by small papules and vesicles. Treatment includes avoiding triggers, taking antihistamines such as ebastine, and applying topical corticosteroid creams. Solar dermatitis is caused by ultraviolet radiation. Mild cases may require no treatment, while severe cases may need topical medications such as hydrocortisone butyrate cream. Additionally, exposure to sunlight should be avoided.

If symptoms persist or are accompanied by fever, pain, or pus discharge, prompt medical attention should be sought for diagnosis and targeted treatment by a qualified physician.

Viral herpes is mainly caused by two types of viruses: herpes simplex virus (HSV) and varicella-zoster virus (VZV).

HSV is divided into HSV-1 and HSV-2; the former commonly causes herpes around the lips, while the latter often leads to genital herpes. VZV causes chickenpox upon initial infection and may reactivate after latency as shingles.

Herpes simplex can cause significant discomfort to patients. However, in most cases, timely treatment with medications such as acyclovir, valacyclovir, or famciclovir can lead to gradual resolution and recovery. For individuals with normal immune function, viral herpes typically does not result in serious consequences and the condition can be effectively controlled with antiviral drug therapy.

In immunocompromised individuals, such as patients with HIV/AIDS, cancer patients undergoing chemotherapy, or organ transplant recipients taking immunosuppressive agents, viral herpes may lead to more severe complications, such as herpetic keratitis, encephalitis, or widespread skin infections.

Once related symptoms appear, prompt medical attention should be sought, and standardized treatment should be followed as directed by a physician.

Acne vulgaris, commonly known as teenage acne, is a prevalent skin condition among adolescents. Whether treatment is necessary mainly depends on the severity of the acne and the psychological condition of the patient.

For mild acne, symptoms can be managed through regular cleansing and over-the-counter topical medications, such as products containing benzocaine, benzoyl peroxide, or salicylic acid. For moderate to severe acne, especially when accompanied by inflammation, cysts, or scar formation, professional treatment is recommended.

A physician may prescribe oral or topical antibiotics, retinoids, and in some cases, oral contraceptives or systemic isotretinoin. Treatment should be individually tailored, avoiding self-administration of inappropriate medications or treatments that may worsen symptoms or trigger other skin problems.

Regular dermatological check-ups can help monitor acne progression, allow timely adjustment of treatment plans, and prevent scarring or pigmentation. If physical discomfort occurs, it is recommended to seek medical attention at a hospital promptly and follow the doctor's instructions for appropriate management.
