There’s been a lot of buzz around peptides, but what are they exactly and do they live up to the hype?
Peptides are short strings of amino acids that, under the right conditions, create proteins in the body. They’re found in every cell and are necessary for cellular health. Peptides also have anti-inflammatory and antioxidant properties. There are many different types of peptides, including collagen peptides that improve skin elasticity and reduce fine lines and wrinkles, and creatine peptides that increase muscle strength and growth. Other peptides may help with weight loss or treat chronic infections and arthritis.
There are multiple ways to synthesize peptides, including chemical synthesis, enzyme-mediated peptide synthesis, cell-free peptide synthesis, and recombinant DNA technology. In general, peptides have a lower molecular weight than full-length proteins and are more easily absorbed by the body’s cells. Peptides also have a unique structure that allows them to form hydrogen bonds with other molecules, making them easier to digest and absorb than proteins.
In the skincare industry, peptides have become a force to be reckoned with due to their ability to regenerate the skin at a cellular level (making it stronger and healthier), while also improving its appearance (firming and tightening the skin, softening laughter lines and wrinkles and minimizing fine lines). The secret behind their success lies in two factors: their small size, which makes them easy to penetrate the skin; and their ability to stimulate specific functions in the skin’s cells.
Aside from anti-aging benefits, peptides have also been shown to reduce inflammation and fight the effects of stress on the skin. In addition, they’re able to penetrate deep into the epidermis, where they can reach the dermal layer and promote cell growth and repair, as well as boost hydration and moisture levels.
Peptide treatments have also been shown to be effective in the treatment of inflammatory and allergic reactions, including dermatitis, rosacea, eczema and contact dermatitis. They can also be used to prevent and treat a variety of medical conditions, including autoimmune diseases, chronic skin ulcers, and fibrosis of the skin.
There are a number of other potential uses for peptides, including their use in the development of antimicrobial agents, antibiotics and other drugs to treat infectious diseases. Additionally, peptides have been shown to have significant potential in the treatment of various cancers and tumors. The discovery of several peptides that inhibit the activity of certain enzymes, such as hyaluronic acid and MDM2/MDMX, is expected to lead to the development of novel cancer therapies.
