What it is
rh-Oligopeptide-1 is a bioengineered peptide identical in sequence to human epidermal growth factor, produced by recombinant expression. In cosmetics it is used as a skin-conditioning agent intended to support the look and feel of the skin. It is typically incorporated at very low concentrations in serums and creams.
Safety & warnings
As a peptide used at very low concentrations, rh-Oligopeptide-1 is generally well tolerated. It is not a fragrance allergen and is not associated with comedogenicity.
Origin & sourcing
Produced by recombinant biotechnology, commonly via microbial fermentation of host cells engineered to express the peptide.
