Why does lime juice severely burn the skin when exposed to sunlight?
gpt
A range of plants which include the citrus family contain active compounds called furocoumarins in their juice. When this compound reacts with uv-a light on skin surface, energy is released through a chemical reaction and this energy gets absorbed mostly by the skin and as a result severe burns, blisters and hyperpigmentation occurs.
This reaction is also known as margarita dermatitis, because lots of cocktails contain some degree of lime or lime juice.
