One of Missha's star products, this ampoule helps to give you a dewy, supple and clear complexion. The key ingredient for this anti-aging serum is Bifida Ferment Lysate, a fermented yeast that visibly reduces signs of aging and improves skin elasticity while protecting the skin. Often compared to Estee Lauder Advanced Night Repair as its less expensive dupe, this serum has developed a cult following due to its ability to repair and hydrate, giving you luminous smooth and even-toned skin with regular use. The formula may be powerful, but it's gentle enough for those with sensitive and acne-prone skin.
