The concept of glass skin, originating from Korean skincare, signifies a healthy, luminous complexion that appears smooth and clear. Alicia Yoon, founder of Peach Lily, explains that achieving glass skin involves nurturing the skin with essential fatty acids, vitamins, and antioxidants. The key steps include using a targeted serum for hydration and brightening, exfoliating regularly to remove dead skin cells, and applying a moisturizer to lock in hydration. Additionally, incorporating a hydrating mask can enhance the skin's glow. A mist or essence can also be used to boost hydration throughout the day. Finally, applying broad-spectrum sunscreen is crucial for protecting the skin from UV damage and maintaining its health. Dermatologist Dr. Michele Green emphasizes that a personalized skincare routine tailored to individual needs can help achieve the best results, making glass skin an attainable goal for many.
