Although the long-term benefits of these products have not been fully tested and evaluated, evidence of the benefits derived from their use is steadily growing. This study describes the peptides, proteins, and growth factors that are most frequently used in cosmeceuticals and discusses their potential benefits and practical use in dermatology.encosmeceutical peptidesgrowth factorsagingCopper complex glycyl-l-histidyl-l-lysine-cu2+Extracellular-matrix productionHuman skin fibroblastsI procollagenExpressionStimulationCollagenElastinProliferationPermeabilityreview10.1111/jocd.122291473-2165393188100031
