About this product
Kiehl's Since 1851 1cc CollaShot Plump Serum is a daily facial serum designed to visibly enhance skin plumpness and radiance. Formulated with recombinant collagen polypeptides, vitamin B12, and rhamnose, it targets wrinkles and supports skin resilience. The bio-engineered collagen fragments help improve firmness, while rhamnose works to reduce the appearance of fine lines. Applied twice daily after cleansing, it should be followed by a moisturizer for best results. Clinical testing showed a threefold improvement in skin plumpness after eight weeks of consistent use.
- Recombinant collagen polypeptides
- Vitamin B12 for radiance
- Rhamnose for wrinkle reduction
- Clinically tested for plumpness
- Daily use morning and evening
- Made in USA
