How to use Sulwhasoo’s best-selling First Care Activating Serum now in its 6th Generation: Use this serum to help strengthen your skin's moisture barrier right after cleansing, when your skin is the most vulnerable. Warm 2-3 pumps of formula into the palm of your hands and take a deep breath and inhale the earthy scent. Then apply the serum to damp skin by pressing serum into skin with an open palm for optimal absorption. #koreanskincare #skincareroutine #skinbarrier
