Introduction
Under normal circumstances, spots around the mouth may be caused by excessive sun exposure, irregular作息 (作息 should be translated as "lifestyle habits" or "作息 habits"), melasma, pityriasis alba, seborrheic dermatitis, and other reasons. The solution should be selected according to the specific cause. In daily life, one should pay attention to sun protection, maintain good作息 habits (作息 habits), avoid using cosmetics containing hormones, and so on, in order to prevent the occurrence of spots around the mouth.

Generally, spots around the mouth may be caused by excessive sun exposure, irregular作息 (作息不良), melasma, pityriasis simplex, seborrheic dermatitis, and other reasons. The solution should be selected according to the specific cause. It is recommended to seek medical attention promptly and follow medical advice for treatment. Details are as follows:

1. Excessive Sun Exposure: Prolonged sun exposure can cause local skin to be stimulated by ultraviolet rays, making melanin accumulate in certain areas and resulting in spots. Adjust lifestyle habits promptly to avoid excessive sun exposure, and take facial sun protection measures when going out, such as using umbrellas and sunscreen.

2. Irregular作息 (作息不良): Long-term late nights and insufficient sleep can prevent the body from resting adequately, generally affecting hormone secretion, leading to localized spots, accompanied by fatigue and irritability. Timely rest is necessary to ensure proper rest, and good作息 habits should be developed.

3. Melasma: Melasma is usually associated with factors such as the use of cosmetics and significant mood swings. It may appear around the lips, typically presenting as brownish-yellow spots, often symmetrically distributed, with generally no specific accompanying symptoms. Follow medical advice to use medications such as tranexamic acid tablets, vitamin C tablets, and glutathione tablets to inhibit fibrin breakdown and provide antioxidant treatment.

4. Pityriasis Simplex: Pityriasis simplex is a type of skin disease commonly seen in children and adolescents. Causes include lack of sleep, excessive sun exposure, prolonged outdoor play, and malnutrition. It presents as pigmented spots with unclear borders, covered with fine, scaly white flakes, possibly accompanied by mild itching. Under medical guidance, medications such as amoxicillin capsules, cetirizine hydrochloride tablets, and dexamethasone acetate tablets should be used for anti-inflammatory treatment.

5. Seborrheic Dermatitis: Seborrheic dermatitis is a common skin condition potentially related to genetic factors, microbial infections, dietary factors, and neurological dysfunction. Patients may present with symptoms such as erythema and desquamation, which may also lead to spots around the mouth, possibly accompanied by flaking. Follow medical advice to use medications such as tacrolimus ointment, selenium sulfide shampoo, and itraconazole capsules for treatment, achieving anti-inflammatory and antibacterial effects.

In daily life, attention should be paid to sun protection, maintaining good作息 habits, and avoiding cosmetics containing hormones to prevent the occurrence of spots around the mouth.
