In general, "pimples" refer to acne. The appearance of numerous acne lesions on the arms may be related to skin friction or irritation, inadequate cleansing, allergic dermatitis, eczema, or seborrheic keratosis. If discomfort occurs, it is recommended to seek professional medical treatment under a doctor's guidance. Specific analyses are as follows:

1. Skin Friction or Irritation

Wearing tight clothing or frequently rubbing the skin on the arms may cause follicular inflammation and lead to acne formation. It is advisable to wear loose, breathable clothing to minimize skin friction.

2. Inadequate Cleansing

Insufficient cleaning of the arm skin may result in the accumulation of dirt, oil, and dead skin cells within pores, leading to clogged pores and acne development. It is recommended to enhance skin hygiene, select a facial cleanser suitable for your skin type, and perform regular deep-cleaning routines.

3. Allergic Dermatitis

Allergic dermatitis occurs when allergens trigger an immune response in the skin of the arms, causing inflammation and acne-like lesions. This condition may be accompanied by intense itching. It is recommended to use medications such as loratadine granules, cetirizine hydrochloride tablets, or chlorpheniramine maleate tablets under medical supervision.

4. Eczema

Eczema is a chronic skin condition that may be associated with genetic and environmental factors. It can impair the skin barrier function on the arms, resulting in skin lesions such as redness and papules that resemble acne. Patients may also experience redness, dryness, and itching; in severe cases, blisters and oozing may occur. It is recommended that patients use medications such as prednisone acetate tablets, cyclosporine capsules, or ebastine tablets under a doctor’s guidance.

5. Seborrheic Keratosis

Seborrheic keratosis is a common age-related skin condition, possibly caused by abnormal keratinocyte proliferation. It manifests as brown or black patches on the arms with irregular borders and rough surfaces, resembling acne. Symptoms may include redness, swelling, heat, and pain. Patients may use topical treatments such as tretinoin cream, tazarotene cream, or adapalene gel as directed by a physician.

Patients are advised to regularly clean their arms and wear loose-fitting clothing to avoid friction, which may help alleviate symptoms.

Can orthodontic treatment improve an asymmetrical face (uneven facial sides)?
In general, whether orthodontic treatment can improve facial asymmetry (uneven face size) depends on the underlying cause. If the asymmetry is caused by abnormal tooth occlusion, orthodontics can usually help improve it. However, if the asymmetry results from uneven skeletal development or facial muscle imbalance, orthodontic treatment is unlikely to produce significant improvement. During orthodontic treatment, it's important to consistently use both sides of the teeth for chewing and avoid favoring one side, which could worsen facial asymmetry.
