Antioxidants are a crucial part of any skin care routine, but they’re especially important for aging skin. See, when your skin is open to the elements (UV exposure, pollution, and so on), it can enter a state of oxidative stress. 

When that state is prolonged, that’s when you’ll see fine lines and wrinkles coming in at a quicker rate. So you need to incorporate antioxidants to fend off those free radicals, but Alexiades notes that green tea extract is a one-of-a-kind type of antioxidant. 

“Green tea extract is one of the most important because it in turn regulates the other key antioxidants in the cell, such as superoxide dismutase4,” she notes. Hence, why Alexiades features green tea (and countless other healthy aging staples) in her line–MACRENE actives.
