HYALURONIC ACID

This naturally occurring acid won’t create more collagen but can make what you have firmer. “It’s a carbohydrate that supports the collagen and elastic fibres in the skin,” says Rodney. Plus, it helps skin stay hydrated by holding a thousand times its molecular weight in water.

How to use it: Choose a moisturiser that contains it and apply it before bed.
