Peptides are a fairly new buzz word in the skincare industry, but peptides have been around since the beginning of time. So, what are peptides? What is their purpose? Do you need peptides in your regimen?   Peptides are chains of amino acids that are building blocks of tiny molecules. The peptide molecules are the basic building blocks of proteins. There are many different types of peptides that can be found in our body, and they all have their own special purpose. Some work as neurotransmitters, others as pain relievers and some are even associated with hormones. There are a few different peptides that relate to our skin and that can be found in skincare products, some of which are palmitoyl pentapeptide-3, acetyl hexapeptide-3, palmitoyl oligopeptide and copper peptides.   Palmitoyl pentapeptide-3 is also known as Matrixyl, and works to stimulate the production of collagen at the deeper layers of the skin while promoting skin strength and helping for the skin to heal quickly. Acetyl hexapeptide-3, also known as Argireline, is an alternative to Botox as it helps to relax facial lines and wrinkles. Palmitoyl oligopeptide is similar to Palmitoyl pentapeptide-3 as it also helps to promote the production of collagen at the deeper layers of the skin. Copper peptides contain a bit of copper in the peptide chain, which helps to promote skin regeneration and healing, thus making the skin stronger.   Peptides are best used in combination with each other, and in addition to other active ingredients. Some peptides, such as the Acetyl hexapeptide-3 work beautifully with vitamin C. Palmitoyl pentapeptide-3 and palmitoyl oligopeptide are similar in their chemical structure so they make a very powerful combination for zapping lines and wrinkles.   Peptides are of utmost importance in a comprehensive skincare regimen, just as important as antioxidants, sunscreen and moisturizer, especially for those concerned with correcting and preventing aging. Regular use of peptides will result in firm, even-toned, lineless skin.   Here are some great products that contain peptides:

  • Kinerase Pro Therapy C8 Peptide Intensive Treatment, which contains vitamin C in conjunction with a peptide blend encapsulated in a creamy serum formula that’s suitable for all skin types, including oily and combination.
  • Celazome N°45 Firming Peptide Cream is an outstanding cream formula that is great for normal to dry skin types. It contains a 45% active concentration of potent peptides such as acetyl hexapeptide-8, palmitoyl oligopeptide, palmitoyl tetrapeptide-7 and acetyl tetrapeptide-9.
