Once you have your simple yet effective skin-care routine nailed, you might then want to add certain products and ingredients — but that all depends on preference and your skin's needs. For example, Oh has noticed a trend towards phytochemicals. "These are very powerful antioxidants," he explains. Plus, the perennially on-trend antioxidant cica (centella asiatica) is showing no signs of slowing down. "I just returned from Seoul on a business trip and it’s clear that it’s still trending," Kinder says. "Centella is rich in amino acids and is great for improving skin elasticity as well as boosting antioxidant activity. It’s known as a great ingredient for calming troubled skin as well."
