Is Lidocaine and Chlorhexidine Aerosol effective for treating sunburn?
I got sunburned a few days ago while traveling, and my skin is now red and painful. I heard someone mention that lidocaine chlorhexidine aerosol can treat sunburn—does it really work?

In general, lidocaine chlorhexidine aerosol has some effect in treating sunburn.
Lidocaine chlorhexidine aerosol contains multiple ingredients including lidocaine and chlorhexidine. Lidocaine acts as a local anesthetic that can effectively reduce the pain associated with sunburned skin. Chlorhexidine, on the other hand, has broad-spectrum antibacterial properties and helps prevent potential skin infections following sunburn.
After sunburn, the skin often becomes red, swollen, and painful; in severe cases, skin damage and infections may occur. The application of lidocaine chlorhexidine aerosol can help alleviate these symptoms to some extent and promote skin recovery. However, medication should be used under the guidance of a physician to avoid self-medication and ensure both effectiveness and safety. Additionally, after applying the medication, further sun exposure should be avoided, direct sunlight minimized, and protective measures such as sunscreen and sun hats should be used when going outdoors.
During the treatment process, a light diet is recommended, along with increased consumption of vegetables and fruits, while spicy and irritating foods should be avoided to facilitate skin recovery.
