Peptides are small molecules that consist of two or more amino acids as well as chains of amino acids. Smaller than proteins, these molecules are synthesized from the constituent amino acids, and are classified according to their number. They are referred to as dipeptides if they have two amino acids, tripeptides with three, tetrapeptides with four, and so on.
A peptide works as a binding agent of moisture and is capable of helping the skin to repair itself, the reason why most face creams have this molecule as an ingredient. To understand how peptides work, however, you need to know about collagen first.
Collagen is your skin’s most abundant protein that exist as fibers woven together to lend support to and provide thickness for your skin. When these fibers diminish, skin develops wrinkles and becomes thin, leading to aging.
Peptide chains act in several ways on collagen to slow down or reverse the aging process. When these peptide chains are incorporated into a peptide cream, they can encourage the skin cells to produce, instead of breaking down, collagen. Additionally, peptide as a facial cream ingredient can control other aspects of aging.
The Three Types of Peptides
There are three types of peptides: neurotransmitter, carrier, and signal. Through a mechanism similar to that of Botox, neurotransmitter peptides can block the release of certain chemicals which cause muscles to contract. Carrier peptides help deliver copper to the skin; copper is an important trace mineral that stimulates collagen production as well as heals wounds.
Also known as copper gluconate, copper peptides can be useful after various forms of laser resurfacing, chemical peels, and dermabrasion, among other treatments, have been applied. This is because copper peptides help to improve skin after it has been remodeled and optimize its healing as a kind of augmentation to the effects of said treatments.
A copper peptide cream is effective against several skin irritations because it has anti-inflammatory properties. These irritations, even those without open lesions, can accelerate skin aging by helping free radical formation. Several treats for skin rejuvenation such as tretinoin found in Retin A and Renova and alpha hydroxyl acids (AHA), for instance, may cause skin irritation which can worsen over time.
Signal peptides signal the skin to stop the breakdown of collage or produce it. Either way, this signal is able to slow down the process of aging, especially wrinkling of the skin. Palmitoyl pentapeptides are the most popular of signal peptides used for cosmetic purposes. Palmitoyl Pentapeptide-4, for instance, has been proven effective against wrinkle formation and sun damage like retinol but is less irritating.
How to Choose the Best Peptide Serum
It will take some time before you can see the results of a peptide cream or serum. It could take between four and 12 weeks of regular use for the peptides to work but the benefits are all worth the wait. Formulated as a serum which contains GHK-CU, the copper peptide with the most scientific evidence supporting it, peptides can take immediate action on the renewal of aging tissues by increasing key protein production.
Not all peptide-containing products are created equal, though, and this is the reason why you should have several guidelines in how to choose the peptide treatment that will work best for you. The first thing you should look for is the amount of peptides contained in the product. The second thing about the best peptide serum is that it will contain peptides like matrixyl and/or argireline.
Matrixyl can help double collagen production to give skin a youthful appeal, reduce the appearance of wrinkles and fine lines, and improve the skin’s firmness. Argireline is another peptide that can make wrinkles less noticeable when you frown or smile; it has the ability to alter biochemical pathways of muscle contraction. Given that, argireline can reduce the action of facial muscles so as to make them contract less forcefully.
Price and Customer Reviews
Some copper peptide cream formulations have astronomical price tags; this is because top rate quality peptides are not cheap and neither are the research, technologies, and man hours of labor that go into their manufacture. Products that are priced too cheaply may not have the quality needed to resolve your anti-aging concerns. If a product’s claim is too good to be true, then it probably is.
Reading customer reviews is another way to find out if a peptide cream or serum is worth your money and your time. A peptide treatment that has more positive than negative reviews is an indication that the product is reliable. Read reviews not only on the product’s official website but on other third party sites as well, especially those who exclusively review skin care and beauty products.
Try the Product, Read the Label, and Buy It from a Reputable Seller
A copper peptide cream will be typically less expensive than its serum form but remember that a serum delivers the benefits more quickly because it will be absorbed faster by the skin. Trying the product may be the best way to find out whether it is suitable for you. Purchase one or two samples before forking out your cash; this way, you would not have spent so much money on something that may not work for you.
Read the label of the sample you have purchased. Some products don’t put labels on their samples. If this is the case, ask for the product’s larger size and read the label on it. Other than copper peptides, a reliable peptide cream or serum will contain other anti-aging ingredients such as hyaluronic acid, vitamins C, A, and E, salicylic acid, polysilicone-15, glycolic acid, C24-28 alkyl dimethicone, matrixyl, and argireline.
On a final note, make sure that you buy only from a reputable seller. Some of these peptide creams may be available in stores but if they are sold only online, see to it that the product is manufactured by a reputable company and purchase it directly from their website. The best peptide serum always comes with a money back guarantee and have excellent customer support and published clinical test results.
