WHAT IT IS: A superfood that’s native to Brazil and was traditionally used by tribes in the Amazon.

BENEFITS: Acai berries are high in antioxidants, which means they’re an excellent anti-ageing ingredient that guards against free radical damage – such as wrinkles, dark spots and fine lines – for brighter, more youthful-looking skin. They also contain amino acids, fibre, essential fatty acids, vitamins, minerals and vitamin C to help to support healthy immune function.
