Swansea uni study finds algae natural UV protection

UV protective algae could be used as a sustainable alternative to sunscreen, research at Swansea University has discovered.

There are hopes microalgae, which cannot be seen by the naked eye, could replace synthetic sunscreens.

The natural products, found in the sea, have a high absorbance of damaging sun rays.

Dr Carole Llewellyn, who has led the research, said algae sunscreen would be better for the environment.
