While lime and lemon are often eaten in the summer, if you get the juice on your skin and then expose that skin to sunlight, it can lead to phytophotodermatitis.
This appears as mild burns, blisters or skin discolouration, usually some 24 to 48 hours later.
After handling citrus, wash the juice from your skin before going outside.
