Hello, sir: The medical term for acne is "acne vulgaris," which includes comedones, papules, pustules, and large cysts, not all of which can be extracted.
There are many reasons for the development of acne, including the following major factors: 1.
Skin type: Some individuals have pores that are prone to excessive keratinization, leading to clogged pores, and sebaceous glands that secrete excessive oil.
2.
Hormonal imbalance: Various conditions can cause this phenomenon, leading to persistent acne in individuals with the aforementioned skin type.
These include: a.
Staying up past 1 AM or poor sleep quality at night.
b.
High stress levels without relief, including academic pressure, life stress, and emotional stress.
c.
Menstruation.
d.
Physical illnesses: constipation, gastrointestinal discomfort, or other ailments.
3.
Endocrine disorders: Thyroid or other hormonal issues.
Therefore, the treatment approach includes oral medications and topical treatments, along with going to bed early, managing stress, and addressing any physical ailments, all of which are essential.
For improving the first factor related to skin type, it is important to go to bed early, manage stress, and consistently use one of the following topical medications: high-concentration alpha hydroxy acids (10-15%), "Acne Control," or retinoids, all of which should be applied once at night, and only one should be chosen.
Additionally, dietary restrictions should include avoiding high-fat, high-calorie foods, coffee, and spicy foods.
If acne continues to occur despite this skincare regimen, chemical peels with alpha hydroxy acids can be added once or twice a month for maintenance.
If following the above methods for more than six consecutive months still results in acne, oral medications and topical treatments should be added.
Oral medications include first-line antibiotics, second-line anti-androgens, and third-line isotretinoin (Roaccutane).
Generally, oral medications need to be taken continuously for more than two months.
Once symptoms improve, it is still necessary to maintain the "consistent" use of the aforementioned topical medications and uphold a normal lifestyle, which can lead to significant improvement.
As for the green beans, bitter tea, and sexual climax you mentioned, there is no scientific research to support their efficacy.
It is important to maintain a positive mood for faster healing.
Wishing you a speedy recovery.

More Info

Acne can be a frustrating and persistent skin condition, and it can occur on various parts of the body, including the thighs, arms, and back. Understanding the causes of acne in these areas and exploring potential solutions is essential for effective management.

Causes of Acne on Thighs, Arms, and Back
1. Hormonal Changes: Hormonal fluctuations, particularly during puberty, menstruation, or due to conditions like polycystic ovary syndrome (PCOS), can lead to increased oil production in the skin. This excess oil can clog pores, resulting in acne.

2. Friction and Sweat: Areas like the thighs and back are prone to friction from clothing or physical activity. This friction, combined with sweat, can irritate the skin and contribute to acne formation. Tight clothing, especially during workouts, can exacerbate this issue.

3. Sebaceous Glands: The skin has sebaceous glands that produce sebum, an oily substance that helps keep the skin moisturized. Overactive sebaceous glands can lead to excess oil, which can mix with dead skin cells and clog pores, resulting in acne.

4. Bacterial Growth: The presence of bacteria, particularly *Propionibacterium acnes*, can contribute to the development of acne. When pores become clogged, these bacteria can multiply, leading to inflammation and the formation of pimples.

5. Diet and Lifestyle: Certain dietary choices, such as high sugar or dairy intake, may influence acne development. Additionally, stress and lack of sleep can affect hormone levels and skin health, potentially worsening acne.

6. Skin Care Products: Some body lotions, creams, or sunscreens can be comedogenic, meaning they can clog pores. It’s important to choose non-comedogenic products, especially for areas prone to acne.

Solutions for Managing Acne
1. Topical Treatments: Over-the-counter topical treatments containing ingredients like benzoyl peroxide, salicylic acid, or alpha hydroxy acids can help reduce acne. These ingredients work by exfoliating the skin, unclogging pores, and reducing inflammation.

2. Proper Hygiene: Regularly cleansing the affected areas with a gentle cleanser can help remove excess oil and dirt. It’s important to avoid harsh scrubs that can irritate the skin further.

3. Avoiding Irritation: Wearing loose-fitting clothing can help reduce friction and irritation on the skin. If you’re active, consider moisture-wicking fabrics that can help keep sweat away from the skin.

4. Dietary Adjustments: Keeping a food diary to identify potential triggers can be beneficial. Reducing sugar and dairy intake may help some individuals manage their acne.

5. Consulting a Dermatologist: If over-the-counter treatments are ineffective, it may be beneficial to consult a dermatologist. They can prescribe stronger topical or oral medications, such as retinoids or antibiotics, and provide tailored advice based on your specific skin type and condition.

6. Lifestyle Changes: Incorporating stress-reducing activities, such as yoga or meditation, and ensuring adequate sleep can positively impact hormone levels and overall skin health.

7. Avoid Picking or Squeezing: It’s tempting to squeeze or pick at acne, but this can lead to scarring and further inflammation. It’s best to leave acne lesions alone and allow them to heal naturally.

Conclusion
Acne on the thighs, arms, and back can be caused by a combination of hormonal changes, friction, bacterial growth, and lifestyle factors. Understanding these causes is the first step toward effective management. Implementing a consistent skincare routine, making dietary adjustments, and seeking professional help when necessary can significantly improve the condition. Remember, patience is key, as acne treatment can take time to show results. If you have persistent or severe acne, don’t hesitate to reach out to a healthcare professional for personalized advice and treatment options.
