What causes white small spots around the mouth and how to deal with them?

    In general, white spots around the mouth may be caused by excessive sebaceous gland secretion, thickened stratum corneum, milia, vitamin deficiency, angular cheilitis, and other factors. Treatment options include general care and medication therapy. Detailed explanations are as follows:

    1. Excessive Sebaceous Gland Secretion

    The skin around the mouth contains numerous sebaceous glands. When these glands produce excessive sebum, pores may become blocked, leading to the formation of white spots. Use oil-control skincare products, such as facial cleansers and toners containing salicylic acid, to help regulate sebum production. Apply deep-cleansing masks regularly and avoid using overly greasy skincare products.

    2. Thickened Stratum Corneum

    Excessive accumulation of the stratum corneum on the skin around the mouth may also lead to the formation of white spots. Regularly perform gentle exfoliation using products containing ingredients such as fruit acid or lactic acid to accelerate skin cell turnover and promote smoother, finer skin texture.

    3. Milia

    Milia formation is associated with excessive sebum production and clogged pores. Milia are small cysts that may appear around the mouth as white spots, typically without specific accompanying symptoms, though they may affect appearance. Maintain proper skin hygiene and avoid squeezing them.

    4. Vitamin Deficiency

    Selective or picky eating habits that lead to vitamin deficiency may cause damage to the oral mucosa, resulting in white spots. Symptoms may include dry, rough skin and oral ulcers. Ensure a balanced diet with sufficient intake of vegetables, fruits, and other vitamin-rich foods.

    5. Angular Cheilitis

    Angular cheilitis is usually caused by bacterial, viral, or fungal infections. Pathogens invading the corners of the mouth cause localized inflammation, resulting in white spot-like lesions, possibly accompanied by redness, swelling, pain, and cracking at the corners of the mouth. It is recommended to follow medical advice and use medications such as acyclovir ointment, erythromycin ointment, or clotrimazole cream for treatment.

    In daily life, adjust your diet, correct picky eating habits, use oil-control skincare products, and maintain cleanliness and dryness in the corners of the mouth.
