A review.This article discusses the potential application of these short chain oligomers in cosmetics and personal care.Peptidomimetics utilize non-natural oligomer backbones, making them resistant to both exo- and endopeptidases.Bioactive peptides are capable of inducing biol. responses by stimulating cell surface receptors, inhibiting protein-protein interactions, inducing protein conformational rearrangements, inactivating enzymes, regulating gene expression levels, etc.
