Octapeptide-45

Octapeptide-45 is a synthetic peptide—a short chain of amino acids—developed to work alongside other peptides in skincare formulations. Peptides are valued in skincare because they can communicate with skin cells to encourage beneficial responses.This particular peptide has been incorporated into multi-peptide systems where it is thought to support the skin's natural production of hyaluronic acid, a humectant that helps skin retain moisture, and to contribute to overall skin firmness and texture.

Octapeptide-45 is believed to signal skin cells to increase production of hyaluronic acid, a naturally occurring humectant that binds water to the skin and supports hydration. It also appears to work synergistically with other peptides in formulations designed to address the extracellular matrix—the structural scaffold that gives skin its firmness and elasticity.In multi-peptide systems, it may help support the natural turnover of collagen and elastin, though the mechanisms are still being investigated. Early research also suggests it may support the skin's healing response, which is why it…

Octapeptide-45 is typically found in serums or treatment products. Apply to clean skin before moisturiser, using the amount specified on the product label. It is often combined with other active ingredients, so check the full formulation to avoid redundancy with other peptides or hydrating ingredients you may already be using.

Peptides are generally well-tolerated by most skin types. No significant safety concerns have been reported with Octapeptide-45 in available studies. As with any new skincare ingredient, introduce it gradually and discontinue if irritation occurs.
