Dermatologists highlight several skincare ingredients known for their collagen-boosting benefits. Products containing recombinant collagen polypeptides, such as Kiehl's CollaShot, have shown a threefold improvement in skin plumpness after eight weeks of use. This serum features a lightweight gel texture and employs a unique delivery system for deeper penetration. It includes rhamnose, a plant sugar that aids in mitigating visible signs of collagen loss, and vitamin B12 for a characteristic pink hue.
