Ingredient dictionary

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.

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 lab-made skin-firming peptide formed from a reaction between acetic acid, cetyl alcohol, and dipeptide-1, which contains the amino acids arginine and tyrosine.

Acetyl hexapeptide-1 is a synthetic peptide composed of the amino acids alanine, arginine, histidine, leucine, phenylalanine and tryptophan.

This synthetic peptide is composed of amino acids (alanine, proline, serine, and glycine). It works to help skin’s layers maintain adequate hydration.

One of several peptides used in skin care products, this ingredient has skin-restoring and water-binding properties, helping it improve both the look and feel of skin.

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

Often called simply "hexapeptide-5", this peptide is derived from the versatile protein versican, which plays a role in skin’s extracellular matrix. Topical use promotes a firmer look and feel.

Acetyl tetrapeptide-11 is a synthetic peptide that helps skin look and feel healthier.

Acetyl tetrapeptide-5 is a synthetic peptide that has calming, smoothing, hydrating, and firmness-enhancing benefits when applied to skin.

Anti-aging peptide that helps visibly restore skin’s natural support.

A highly targeted multi-peptide that helps skin's supportive elements resist further damage while working to repair visible signs of ageing.

One of several peptides used in skin care products, this ingredient has skin-restoring and water-binding properties, helping it improve both the look and feel of skin.

Azelaoyl bis-dipeptide-10 is a synthetic peptide built around naturally-derived azelaic acid that offers brightening and antioxidant benefits.

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 promising peptide for skin, but more research is needed.

This peptide developed by the brand OneSkin is said to interrupt a hallmark of aging known as cellular senescence.

A peptide blend that supports skin's own collagen by helping to firm and reduce the look of lines on skin and lips.

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

These substances regulate how certain cells behave and could improve numerous skin conditions.

This lab-made peptide is engineered to help skin’s surface cells slough off at their normal rate. This benefit complements leave-on exfoliants and leads to a visibly smoother, less lined complexion. \

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.
