Peptides, short-chain amino acid polymers, and proteins, long-chain amino acid polymers, are formed by the combination of 20 naturally occurring amino acids in the body. Peptides are widely distributed throughout the body, and there are hundreds of distinct peptides, each with a unique purpose. It is still early days for the cosmetics industry’s usage of peptides, but there is a lot of promise. Due to the bigger structure of proteins such as collagen, peptides are more often utilized in cosmetic goods than proteins. Proteolytic enzymes may be used to hydrolyze proteins in order to make them easier to penetrate. Cosmetic peptides are mainly synthetic and have been designed for particular biological functions and skin penetration. Palmitoyl groups are commonly added to peptides to increase oil solubility, which is a popular modification to increase penetration. In nature, peptides are big, water-soluble, and negatively charged at physiological pH, all of which make them difficult to penetrate the epidermis.
Types of cosmetic peptides
To categorize them; we have enzyme inhibitors, carrier, neurotransmitter, anti-microbial, and signaling enzyme inhibitor peptides, as well as signaling peptides. Peptide enzyme inhibitors suppress enzymes in the body, such as tyrosine, which is involved in melanin synthesis, and MMPs, which tear down collagen directly or indirectly. Trace elements, like copper and manganese, are transported by carrier peptides during wound healing and enzymatic activities. Peptides that block the release of the neurotransmitter acetylcholine, which is required for muscle contractions, reduce wrinkles and expression lines. They have antibacterial action, wound healing capacity, and enhance the skin’s inherent immunity, among other things. By leveraging the skin’s natural rejuvenation feedback loop, signaling peptides also stimulate matrix protein synthesis in the skin, particularly collagen.
In order for skin fibroblasts to generate more structural proteins, such as elastin and collagen, signal peptides must first excite them. Because mature skin has lower amounts of collagen and elastin than younger skin, signal peptides make the skin seem firmer and fuller.
Carrier peptides transport copper, magnesium, and other trace metals to the body, where they assist in wound healing and the activity of enzymes. These peptides are also referred to as “penetrating peptides” and “membrane transduction peptides,” among other names. Because of the trace elements they provide, collagen production, skin elasticity, and skin look are all improved, resulting in a decrease in fine lines and wrinkles on the face.
Accutase inhibitor peptides are neurotransmitter inhibitors that block the release of acetylcholine via a number of mechanisms. These peptides work by blocking the release of the neurotransmitter, which causes the contraction of facial muscles to be reduced, resulting in wrinkles being relaxed. Some kinds of wrinkles may be decreased by about 30%, according to some studies. Argireline, for example, is an inhibitory neurotransmitter peptide that is used in cosmetics because it prevents the production of the SNARE receptor from being formed.
Peptides that suppress the production of ACE relax blood arteries and may promote lymphatic drainage. They may be used in cosmetic compositions to decrease the buildup of fluid and alleviate puffiness, such as that seen beneath the eyes.
Peptides in Cosmetics: What Are the Effects?
A variety of advantages have been discovered for beauty peptides, including the reduction of fine lines and wrinkles, the evenness of skin texture, the elimination of acne, and even skin lightening and brightening effects, according to research.
Many novel skincare peptides have been discovered in the past twenty years, and they have shown significant benefits to the skin. Cosmetic peptides, in particular in the area of anti-aging, have shown noticeable results in the treatment of fine lines, wrinkles, and sagging.
Recent studies have also shown that cosmeceutical peptides include bigger molecules that are capable of crossing the skin barrier, particularly in the case of dry and aging skin. Synthetic cosmetic peptides are now routinely changed to perform a variety of tasks, including increased skin penetration, improved stability and solubility, and other improvements.
Research into Topical Peptides for Skin
A a significant rise has occurred in the usage of peptides in the cosmetics industry since the year 2000. They provide a variety of advantages for the skin and hair, ranging from anti-aging to whitening.
Cosmetic peptides are safe, according to research, despite the fact that not all have been authorized by the FDA. They have shown nontoxicity and stability. Additionally, studies have shown that topical cosmetic peptide treatment may substantially enhance the skin.

Acetyl Hexapeptide-3, commonly known as Argireline
Acetyl hexapeptide-3 is a peptide fragment of SNAP-25, which is a substrate for Botox. It is synthesized in the laboratory (Botulinum toxin). When administered as a solution to particular regions of the face, acetyl hexapeptide-3 has been proven in research tests to decrease the deep creases and lines that appear around the forehead and eyes. Acetyl hexapeptide-3 suppresses the processes that cause muscles to move or contract – for example, while generating facial emotions such as smiling or frowning – by blocking the activities of enzymes that induce muscular contraction.
Copper peptide GHK-Cu – also known as GHK or GHK-Cu
In addition to being a tripeptide, GHK-Cu also has a very high affinity for copper. A number of scientific studies carried out in various research laboratories have suggested that GHK-Cu can promote wound healing by attracting immune cells, having antioxidant and anti-inflammatory effects, stimulating collagen and glycosaminoglycan production by fibroblasts in the skin, and promoting the growth of blood vessels.
Matrixyl Palmitoyl-Pentapeptide 3 (also known as Palmitoyl-Pentapeptide 3)
Palmitoyl-Pentapeptide 3, also known by the trade name Matrixyl, is a fatty acid that has been combined with amino acids. One research conducted by the ingredient producer, Sederma, was the only one that had any relevance for skin renewal. The accuracy of this research cannot be determined in the absence of independent corroborating evidence.
Acetyl Glutamyl Heptapeptide-1, commonly known as SNAP-8
A novel new peptide, Acetyl Glutamyl Heptapeptide-1 (SNAP-8), has been proven in recent tests to decrease the severity of existing facial wrinkles while also being effective against the formation of new wrinkles. The anti-wrinkle octapeptide SNAP-8 is an extension of the well-known hexapeptide Acetyl Hexapeptide-3, which is also known as Argireline in the cosmetics industry
