Can geranium be used to treat sunburn?
Geranium can be used to alleviate mild sunburns, but it is not recommended for severe sunburns or when the skin is broken. Medical advice should be followed when using it, with specific analysis as follows:

For mild sunburns, such as redness, slight pain, and warmth of the skin, geranium may be used under medical guidance. The active ingredients in geranium can help reduce inflammatory responses and promote skin recovery. Applying geranium in the form of ointment or soaking solution to the sunburned area can effectively relieve discomfort and accelerate skin healing. This approach requires ensuring no allergy to geranium and performing a small patch test before use.
If the sunburn is severe, such as blistering, skin damage, intense pain, or extensive redness and swelling, geranium should not be used. In such cases, the skin barrier is already compromised, and direct application of geranium may cause irritation or infection, worsening the symptoms.
If the sunburn is severe, with symptoms such as blistering or skin ulcers, prompt medical attention should be sought. Preventive measures should also be taken regularly, avoiding prolonged exposure of the skin to strong sunlight.
