We spend a huge amount of time and money protecting, treating and correcting our skin - serums to brighten, creams to plump, treatments to smooth away what's already changed. What we spend far less time thinking about is what skin actually needs to keep doing its job well in the first place.
The answer, according to a growing number of aesthetic doctors, comes down to protein. More specifically, amino acids - the building blocks that keep skin structurally strong, in much the same way protein keeps muscle strong. And from our late twenties onwards, skin starts running low on them.
