Scientifically called Rosmarinus officinalis, rosemary is a woody, perennial herb with fragrant, evergreen, needle-like leaves and flowers that bloom white, purple, or blue. Whether you add it to your food, steep it as a tea or take it as a supplement, the antioxidants in rosemary help prevent skin damage and maximize skin tone by neutralizing free radicals. Free-radical damage compromises the support structure in your skin, leading to wrinkles, sagging and uneven skin tone. This flavorful herb is a good source of iron, calcium and vitamin B6, which supports healthy collagen levels. Rosemary is also a rich source of manganese, a mineral that helps minimize wrinkles and protects the skin from damage.
