Rosemary may be your favourite herb to use while Summer barbecuing, but it can also help with everything from skin elasticity to collagen development and skin moisturising. Since it's also packed with minerals that help with external skin damage, it's perfect for Summer skin that's been out in the sun for a little too long. Used in an oil infusion, it's great to add to a cleanser, or simply dilute it in water for a cleanser.
