Sunbathing without sunscreen can be dangerous. But it’s not just your skin you need to be worried about: some substances in drugs, cosmetics and medicinal herbs can be toxic to the skin when exposed to ultraviolet light. Experts call the phenomenon phototoxicity. It occurs when a substance absorbs light energy and is thereby chemically modified. Only the modified substance is toxic to the skin, which can cause redness, swelling or inflammation – similar to a sunburn. Companies can examine the phototoxicity of a substance with an in-vitro test method.
