Serum This is a product specifically for the glabella, targeting age-related signs in the "Stinging Cosmetics Series." The most distinctive feature of stinging cosmetics is the shape of the needles. This innovative beauty method directly delivers beauty ingredients to the stratum corneum by solidifying the beauty ingredients themselves into needle shapes and directly inserting them into the skin. The needle ingredients are packed with beauty ingredients that address deep concerns in the glabella, such as "relaxing ingredients*1" that target the wrinkles in the glabella caused by frowning or stern expressions, and "hyaluronic acid*2" to combat dry skin and lack of firmness. The patch is shaped to fit the glabella area, and the adhesive part uses hydrocolloid material, which provides high adhesion but is less likely to irritate the skin, allowing you to use it while sleeping. Apply it twice a week before bed to care for stubborn age-related signs in the glabella. *1 Acetyl hexapeptide-3, pentapeptide-18 (skin softening ingredients) *2 Ingredients that provide firmness and moisture BKv037R Boxed set
