Kiehl's Since 1851 CollaShot Plumping Serum is a targeted skincare treatment designed to enhance skin firmness and reduce visible signs of aging. Formulated with recombinant collagen polypeptides, it supports the skin's natural structure by reinforcing its matrix. The serum uses a Supra-Liposomal delivery system to penetrate up to ten skin layers, improving effectiveness. It also contains rhamnose to address collagen degradation and vitamin B12 for a distinctive pink hue. Applied daily to cleansed skin, it prepares the face for moisturizer and helps maintain a smoother, more youthful appearance over time.
