Can povidone-iodine be applied to pimples on the face?

Acne, commonly known as pimples, generally can be treated with povidone-iodine solution on the face. However, consultation with a doctor is recommended before use. Detailed explanation is as follows:

The formation of acne is usually associated with bacterial infections, such as Propionibacterium acnes. Povidone-iodine has broad-spectrum antibacterial properties and can denature bacterial proteins, effectively killing bacteria around acne lesions, suppressing further development of inflammation. For acne with obvious inflammation and symptoms such as redness, swelling, and pain, applying povidone-iodine can reduce bacterial load, alleviate inflammation, promote acne recovery, lower the risk of infection spreading, and help prevent the worsening of acne into more severe lesions such as cysts or nodules.

Facial skin tends to be delicate, but povidone-iodine generally does not cause significant irritation to healthy skin and is unlikely to provoke adverse reactions such as allergies, redness, swelling, or burning. Even if there is minor skin damage around the acne, povidone-iodine can disinfect while minimizing harm to the skin, avoiding further discomfort, making it suitable for disinfection on sensitive areas like the face.

During the use of povidone-iodine for acne treatment, it is important to maintain a light diet, avoid spicy, greasy, and sweet foods, consume more vegetables and fruits, and keep bowel movements regular.
