Suitable for all skin types, including sensitive skin, Collistar’s Collagen and Glycogen is a concentrated drop treatment formulated to visibly firm and smooth skin. Amino acids from plant-based collagen are combined with glycogen, working to firm and plump the look of fine lines and promote a more defined appearance to facial contours. Suitable for the face and neck, the firming drops can be applied as part of your morning or evening skincare routine.
