Sunscreens have constantly been scrutinized for further improvement in terms of longevity and composition, on account of it being a high demand product. So this new mixture made out of all natural ingredients with long lasting protection, would be more than welcome.
The ingredients are particular components found in algae and reef fish mucus to concoct a material that blocks both types of UV rays- UV-A (melanoma inducing) and UV-B (causing sunburns).
Current sunscreens have achieved this, but the chemicals used in their making are questionable to our health for long term use, and accidental ingestion.
This discovery of using algae and reef fish mucus is not recent. Scientists have been trying to incorporate a naturally obtained substance, mycosporines, for quite some time in facial sunscreens. But, the mycosporines would just smear and dribble too much to be of any use.
The use of a technique called polymer scaffolding turned out to be the solution. The primary polymer used was chitosan, which is derived from the crustaceans (crabs and shrimps), proved to sustain the film of sunscreen intact for over 12 hours. A wide range of polymers could be used and, this films showed effectiveness both indoors and outdoors of cloths and furniture.
The next step would be to introduce this as a facial brand sunscreen. The FDA would probably readily approve of the products as it uses all natural ingredients.
