Hello, radiance. This set brings together four two-part facial ampoules, each with 0.8 g of pure vitamin C powder and 8 ml of ampoule liquid. The two components stay separate until you activate and mix each unit.

Pure vitamin C supports brighter-looking radiance and helps improve the look of visible lines and wrinkles. Idebenone, glutathione and tranexamic acid form an antioxidant blend that supports a more radiant-looking complexion, while idebenone also helps prevent moisture loss.

Once mixed, the ampoule becomes a silky liquid with a non-sticky feel. It’s a focused option when dullness or visible lines are on your mind, particularly if your skin tends to run dry.

The formula contains lavender, bergamot, rosemary, matricaria and Anthemis nobilis flower oils. If you have an essential-oil allergy, skip this one.
