Adopt the Korean "chill skin" routine with this sheet mask infused with soothing Heartleaf and collagen. After cleansing and applying lotion/toner, place the mask on your dry face, adjust it to fit the contours, and leave it on for 10–15 minutes. Remove it, massage the excess essence until absorbed without rinsing, then follow with your moisturizer. Use it 2 to 3 times a week, especially on evenings when your skin feels heated, sensitive, or lacks elasticity.
