Why we love it: Pyunkang Yul Moisture Serum centers on Astragalus Membranaceus Root Extract, replacing purified water to deliver antioxidant energy that supports a balanced, resilient complexion. The lightweight formula strengthens the skin’s moisture barrier and restores harmony between oil and hydration, leaving skin feeling refreshed rather than weighed down. Olive Oil adds a gentle, protective layer to minimize moisture loss while maintaining a visibly fresh, non-sticky finish. Clinically tested and rated non-irritating, this serum is suitable for sensitive or reactive skin and pairs well with a minimalist skincare routine that prioritizes comfort and stability. Description: The Moisture Serum from Pyunkang Yul is engineered to restore skin balance by emphasizing true hydration over sheer water content. By using Astragalus Membranaceus Root Extract as a base, the serum delivers flavonoids and saponins that support the skin’s barrier and help calm imbalance between moisture and oil. Olive Oil provides a light protective layer to lock in hydration and maintain a fresh surface feel. The result is a lightweight, non-greasy serum that absorbs quickly, making it ideal for twice-daily use and compatible with other Pyunkang Yul products to create a balanced oil–moisture synergy. How to use: After cleansing and toning, apply an appropriate amount evenly over the face and pat gently for absorption. For best results, use twice daily and layer with other Pyunkang Yul products to enhance the oil–moisture balance. Allow the serum to set before applying moisturizer or sunscreen.
