The Mizon Face Lifting Set is a two-step skincare routine that helps tighten and tighten the skin. It includes: Hyaluronic Acid Serum 100: This serum contains 100% hyaluronic acid, a powerful moisturizer that plumps the skin and reduces the appearance of wrinkles.  Hyaluronic acid is a natural substance that resides in the skin and helps keep it hydrated and plump. Collagen 100 Serum: This serum contains 90% collagen, which helps improve skin elasticity and firmness.  Collagen is a protein that breaks down as we age, so taking it topically can help.
