Kale, also known as a superfood, contains nutrients that can support healthy skin, hair, and bones. One of those vital nutrients, vitamin c is known for its anti-oxidant properties and its role in collagen synthesis which makes it an important molecule for skin health.
It is believed that the antioxidant properties of vitamin c protect against the ultraviolet light-induced damage caused by free radicals. This kind of oxidative damage can lead to changes in skin structure.
Observational studies found that higher intakes of vitamin c are associated with increased production of collage, better skin appearance and a notable decrease in skin wrinkling.
