Is applying physiological saline solution effective for treating pimples?

In general, applying normal saline to pimples can have certain auxiliary effects, but it cannot directly cure them and should be combined with other treatment methods.

The main principle of using normal saline on pimples is to assist in improving acne conditions through its cleansing, antibacterial, anti-inflammatory, and skin osmotic pressure-regulating properties. Normal saline can remove dirt and oil from the skin surface, reduce pore blockage, and help prevent and improve acne problems. At the same time, salt has certain antibacterial properties; applying normal saline to the face can help reduce skin inflammation and inhibit bacterial growth, thus alleviating redness, swelling, and infection associated with acne. The pH of normal saline is close to the skin's natural pH, and applying it to the face helps regulate the skin's acid-base balance and reduce skin inflammation.

However, it should be noted that normal saline alone cannot completely cure acne. The causes of acne are complex and may be related to multiple factors such as hormonal imbalances, excessive oil secretion, bacterial infection, and lifestyle habits. Relying solely on applying normal saline to the face may not be sufficient to address the underlying issues. A comprehensive approach to treating acne is usually more effective, including maintaining good skin hygiene, eating a healthy diet, avoiding squeezing pimples, and using appropriate skincare products and medical treatments.
