Elastin peptide · skin elasticity
A cosmetic ingredient made by attaching palmitic acid, a fatty acid, to the six-amino-acid sequence valine-glycine-valine-alanine-proline-glycine (VGVAPG). That sequence repeats many times in elastin, the stretchy protein that lets skin spring back. The fatty tail makes the peptide more fat-soluble. Older labels used the retired name palmitoyl oligopeptide, and it also goes by the trade name Biopeptide EL.
Short fragments of structural proteins can act as signals when the larger protein breaks down. In cell experiments, unmodified VGVAPG drew fibroblasts and monocytes toward it at very low concentrations, and antibodies against elastin blocked the effect, suggesting this sequence carries part of the signaling activity of elastin fragments1. The cosmetic rationale is that supplying the fragment might prompt fibroblasts to rebuild matrix, which has not been shown in people.
A 2025 study added a physical angle: in skin donated after cosmetic surgery, the palmitoylated peptide entered the stratum corneum and epidermis, self-assembled into a gel using the skin's own ions, and helped restore barrier strength after the skin's lipids were stripped away2.
The evidence is mostly laboratory work. Unmodified VGVAPG attracted fibroblasts and monocytes in cell assays1. In 2025, a team including Estée Lauder scientists applied palmitoyl hexapeptide-12 to full-thickness skin from a single donor and tracked it with mass-spectrometry imaging, Raman microscopy, and mechanical measurements; it permeated the outer layers, formed a gel, and strengthened delipidated skin2. That was skin outside the body, not living people. A 2026 bioinformatic screen by Procter & Gamble scientists found its sequence resembles skin matrix proteins such as elastin and collagen, without flags for known toxins or allergens3.
A 2021 review noted that, under its older name, its benefits are documented only for skin-aging products, with most of the information in patents and supplier brochures rather than peer-reviewed journals4. No peer-reviewed controlled human trial of this ingredient alone was found.
Not approved as a drug by the FDA or any other regulator found; it is used as a cosmetic ingredient3. In the US, cosmetic ingredients do not need FDA approval before they go on the market5.
Published human studies of this ingredient are too few to describe side effects. A bioinformatic screen did not flag its sequence as resembling known toxins or allergens3, but that is a computer prediction, not clinical data. As with any topical cosmetic, the finished product can irritate skin or cause contact allergy.
