Our Daily Skin Firming Serum is made with pure, natural ingredients and is free from synthetic chemicals and preservatives. As a result, the shelf life is naturally limited. When stored in a cool, dry place and kept out of direct sunlight, this serum is expected to last between 12-24 months. To fully experience its skin-firming benefits, we recommend using it daily. Always apply with clean, dry hands to maintain the product’s purity and freshness.
