Introduction
Azelaic acid gel and metronidazole gel generally do not need to be washed off after application. The main ingredient of azelaic acid gel is azelaic acid, which can effectively alleviate mild to moderate inflammatory acne vulgaris. The primary component of metronidazole gel is metronidazole, which is used to treat inflammatory papules, pyoderma, rosacea erythema, and similar conditions.
After applying azelaic acid gel or metronidazole gel, it is generally not necessary to wash them off. Specific details are as follows:
Azelaic acid gel contains azelaic acid as its main ingredient and can effectively alleviate mild to moderate inflammatory acne vulgaris. Metronidazole gel primarily contains metronidazole and is used to treat inflammatory papules, pustules, and erythematotelangiectatic rosacea. Both medications have low irritation and are usually well-tolerated by patients' skin. Therefore, there is no need to deliberately wash them off after application; instead, gently massage the affected area to promote full absorption of the medication. However, the skin should be cleaned before application. Since both drugs are anti-anaerobic agents, cleaning the local skin prior to use helps prevent dust and bacteria from interfering with drug absorption.
Patients are advised to visit a正规 hospital and follow medical guidance when using these medications. Avoid self-medicating blindly to prevent adverse effects. During treatment, avoid spicy, stimulating, and greasy foods. Consume more fresh fruits and vegetables.
