Can sodium chloride injection be used as a facial mask?
Sodium chloride injection is a 0.9% isotonic saline solution, primarily used to treat dehydration and electrolyte imbalances caused by various conditions. It also possesses mild anti-inflammatory and antimicrobial properties. So, can sodium chloride injection be applied topically to the face?

Can Sodium Chloride Injection Be Used for Facial Application?
Yes, sodium chloride injection may be applied to the face. This solution exhibits anti-inflammatory effects, and prolonged topical use may help improve acne. Individuals with hormonal imbalances or oily skin may use it as an adjunctive regulatory measure. Sodium chloride injection can provide soothing relief for allergic skin reactions and offers mild anti-edematous (anti-swelling) effects; however, it is not a definitive treatment for allergic dermatitis. While using this solution, avoid consuming unhygienic foods—such as barbecued items—and instead increase intake of fresh vegetables and fruits. Also, ensure adequate sleep and avoid staying up late.

Note: The preceding paragraph incorrectly describes sodium chloride injection as a broad-spectrum antifungal agent. In fact, sodium chloride injection has no antifungal activity. The description provided here mistakenly conflates sodium chloride injection with another drug—likely fluconazole or a similar antifungal agent. Sodium chloride injection is simply sterile saline; it does not possess antifungal properties nor is it indicated for systemic fungal infections such as candidiasis, cryptococcosis, or histoplasmosis. Its clinical uses are limited to fluid and electrolyte replacement, irrigation, and as a diluent or vehicle for other medications.
The above addresses the question of whether sodium chloride injection can be used for facial application. We hope this information is helpful to you.
