Ingredient dictionary

A neurotransmitter-inhibiting peptide, meaning it could have the ability to target expression lines (though more research is needed to confirm).

Synthetic peptide derived from rice, intended to mimic skin growth factors. We are awaiting research to fully assess the efficacy/benefits.

A promising peptide for skin, but more research is needed.

A synthetic peptide that is based around octapeptide-3, a peptide complex composed of the amino acids aspartic acid, glutamic acid, glutamine, and methionine.

An anti-aging tetrapeptide that works to keep skin youthful, addressing firmness and sagginess by helping to inhibit protein-degrading enzymes within skin’s surface.

A synthetic peptide that some research has shown could have anti-acne benefits.

Extract of yeast fermented in the presence of calcium ions. It has no known benefit for skin but theoretically could help boost hydration.

Extract of yeast fermented in the presence of copper ions.

Extract of yeast fermented in the presence of iron ions.

An anti-aging tetrapeptide that works to keep skin youthful, addressing firmness and sagginess by helping to inhibit protein-degrading enzymes within skin’s surface.

Copper peptides combine the element copper with three amino acids. Copper peptides occur naturally in the body, and are used in trace amounts for anti-aging benefits.

A “neuropeptide” with promising research backing its ability to visibly reduce the appearance of expression lines and wrinkles.

A synthetic peptide that has hydrating benefits for skin.

This synthetic peptide made of five amino acids helps skin look and feel smoother.

This peptide could have a positive impact on receptors in skin that influence signs of aging.

Cosmetic ingredient derived from cultures of human fibroblasts, containing growth factors and exosomes that have potential to rejuvenate skin in variety of ways.
