At Swissline, we have always been intrigued by peptides! They can be lab-built, structural blocks identical to various forms of the skin’s own proteins. This gives them skin-restorative capacities, not only as contributors to tissue density but also as “messengers” allowing the sending of signals between cells, to facilitate – or oppose! – specific metabolic paths.
You just have to envision a mechanism for sending the messages you want to put across, block or even silence. Peptides are a significant chunk of what smart skincare means; even if they tend to be a challenge from the formulation point of view as they are vulnerable to attack by enzymes naturally present in the skin. Synthetic peptides are a good way to showcase why “natural” is not always synonymous with better… they are engineered to resist those attacks, making them clearly the way to go for any serious skincare formulation.
