This article looks at the actual science behind anti aging peptides - what they are, how they work, which ones do what. -And whether they are really worth using (paying for?!) in your skin care products...
Simple answer: yes they are. But there are significant "buts"!
A peptide is a molecule that directs certain functions of skin. Similar but smaller than a protein, they are made up of a chain of amino acids. They get other molecules to do things and they cause things to happen (for example an increase in collagen production) (1):
Peptides can do the following:
Ok, so why care about peptide details? Because: this info shows you just how beneficial they really can be for your skin.
It also highlights the importance of the right formulation for a skin care product - anything active needs to be stabilized, in a high enough dose, and in a form that can actually be delivered into skin in order to show results.
Below, let's look at 3 of the best, scientifically backed anti aging peptides:
3 scientifically backed anti aging peptides:
What do copper peptides do:
Copper plays a significant role in wound healing, the new development of blood cells, and in aiding chemical processes within the skin (including collagen and elastin production) (1).
In other words, it can help smooth and thicken skin, improve its texture, and combat other signs of aging. This is one amazing and important metal element!
This cool peptide has been shown to play a role in the increased production of collagen - a well-controlled 12 week clinical trial showed significant improvement in fine lines, wrinkles and skin texture with its use (1).
In order to be devliered into the skin, it needs to be linked with palmitic acid - these two combined peptides are marketed in the skin care industry as "Matrixyl*".
The peptides that work in a similar way to Botox are called "neurotransmitter-affecting peptides" (1). Basically, as mentioned above, they make it harder for muscles to move, which results in less movement (duh) and therefore a reduction in and/or prevention of fine lines and wrinkles.
Again, they have not been shown to work as well as Botox itself. However, their results are promising, and a lot less daunting than a needle! (Probably a lot more natural looking too).
Anti aging peptides do work and can make a significant difference to your skin.
Knowing how they work and the scientific backing behind them is really important in making the right decisions for your skin care.
It is the difference between an expensive skin care product that is essentially useless despite the promises on its label, and one that will actually make a difference!
