Generally, povidone-iodine cannot completely eliminate acne and only has an auxiliary anti-inflammatory effect on some superficial acne lesions. Moreover, it carries certain risks and is not recommended as the first-line method for acne treatment.

Povidone-iodine has a broad-spectrum bactericidal effect and can inhibit the proliferation of bacteria such as Propionibacterium acnes. It may provide auxiliary relief from inflammation and redness associated with superficial acne caused by bacterial infection, such as papules and pustules. However, it is important to note that povidone-iodine cannot penetrate deeply into hair follicles to eliminate deep-seated bacteria, and therefore has limited effectiveness on deeper forms of acne such as nodular or cystic acne. Additionally, it cannot regulate sebaceous gland secretion or improve abnormal follicular keratinization, which are central to the pathogenesis of acne.

For the treatment of acne, appropriate methods should be selected based on the severity of the condition. Mild acne can be managed by maintaining facial cleanliness and using topical medications containing ingredients such as salicylic acid or benzoyl peroxide. Moderate to severe acne may require systemic treatments such as oral antibiotics, retinoids, or isotretinoin. Before using any medication, it is advisable to consult a dermatologist and develop a suitable treatment plan based on individual circumstances.
