Not only is this a good working artificial skin, it also displaces the use of live animals in lab work. Since the latter aspect is an ongoing public relations disaster decades old, it could not be more welcome.
Otherwise, this should provide a framework for completely healing damaged skin back to close to original state.
I do not know how long before this is available but it should be rather quick. It is very good news and should also facilitate improvements in cosmetic surgery.
Scientists create artificial skin that stretches like the real thing

Spain’s have created artificial skin with the resistance, firmness and elasticity of real skin. It is the first time artificial skin has been created from fibrin-agarose biomaterial. Fibrin is a protein involved in the clotting of the blood, while agarose is a sugar obtained from seaweed, commonly used to create gels in laboratories. The new material could be used in the treatment of skin problems, and could also replace test animals in dermatological labs. University of Granada
The researchers started by obtaining plasma samples from human donors, and separating out the fibrin. They then added calcium chloride, to precipitate coagulation, tranexamic acid, to keep the coagulate from breaking down, and 0.1% agarose. The resultant material was grafted onto the backs of hairless mice, where its bio-compatibility with living organisms could be observed.
The mice showed no signs of rejection or infection, and healing of the grafted area began within six days - within 20 days, the wounds were fully healed.
Previously, artificial skin has been made from biomaterials such as collagen, polyglycolic acid, and chitosan. The fibrin-agarose skin, however, looks particularly promising. Prof. Jiménez Rodríguez, one of the researchers, stated "Definitively, we have created a more stable skin with similar functionality to normal human skin."
