Five or ten years ago, the use of peptides was all the buzz and any product that contained one seemed worth a try. It was the next big thing since alpha-hydroxy acids and then antioxidants. By now in 2013, there are hundred if not thousands of different peptide-based skin care products available. You can choose from a $2.99 bottle of cream advertised on Amazon as an “Antioxidant-Peptide Complex” or a pair of “Private Reserve” neuorpeptide serums retailing at Nordstrom for $475. How to choose?
We will stick to the basics and discuss two “workhorse” peptides that have appeared in many different formulations for over five years. Matrixyl (different from Matrixyl-3000) is a tradename for the palmitoyl pentapeptide-4 anti-aging ingredient. In short, it helps your skin build collagen so it diminishes wrinkles and improves elasticity. In fact a 2013 study by researchers at University of Reading concluded it has potential to nearly double the amount of collagen you produce and also stimulate your own hyaluronic acid production. Cosmetic studies for products which include the peptide report that people see improvements in wrinkle reduction and hydration. This ingredient seems to be very beneficial without sideeffects and suitable for any skin type – so the only question being how much are you willing to pay to get a higher percentage of this particular peptide in your product!
Argireline (the trademark name for Acetyl Hexapeptide-8) is a peptide that is also in widespread use in skincare. Its advertised as a sort of “topical Botox”. The theory is that it prevents key neurotransmitters from firing – and this lockdown prevents muscles from contracting to product deep wrinkles – like those between the eyebrows. It stormed onto the scene (along with a host of other peptides) in Peter Thomas Roth’s much-loved Un-Wrinkle product, and its extremely common in peptide-based eye treatments like and instant-results products for fine lines and wrinkles. One of the reasons peptides are popular is that we consider them safe adjuncts to your routine and they avoid sideeffects. However, if you look for information about Argireline online, you can find “the good and the bad” when it comes to reviews. Many people profess infatuation with an intstant tightening while others report long-term sagging. This short article on smartskincare.com provides a great synopsis of what we know about the peptide to-date, and maybe some reasons to use it cautiously.
