Despite being around for years, peptides continue to garner significant buzz throughout the skin care industry. The touted benefits are numerous, including reduced wrinkle depth, tightening and smoothing of facial contours, increased hydration, and stimulation of the immune system. Peptides’ promises run deep, and while skin care products have traditionally utilized peptides that are synthetically sourced, plant-derived peptides offer a natural alternative, free from potential side effects and preservatives associated with their synthetic counterparts.
