Wat zijn petiden en hoe gebruik je ze in je skincare routine
Peptide toevoegen aan je skincare routine is een van de ant-iaging hacks die ik iedereen adviseer te doen. Peptiden zijn namelijk een van de doeltreffendste werkstoffen die er bestaan om rimpels te verminderen en de huid weer stevig te maken. Hier lees je alles wat je moet weten voordat je dit collageenverhogende ingrediënt in je skincare routine opneemt. Imagine having a direct connection to your skin cells. “Hey, I'm starting to see some lines between my eyebrows,” you might tell them. “Can we double collagen production this week?”
Maar omdat direct contact met je huidcellen waarschijnlijk nog wel even op zich laat wachten, zou je kunnen overwegen om in de tussentijd huidverzorging te kopen die peptides contain . Peptides communicate with our skin cells as small packets, so they can communicate with each other more efficiently and fight and slow down wrinkles and lines. With that in mind, peptides are one of the strongest substances we have for reducing wrinkles and firming the skin. If your interest is sparked, read on to learn how peptides work, and how you can reap their benefits.
What are Peptides?
Peptides are short chains of amino acids, where the amino acids are the smallest building blocks of a protein. And proteins in the form of elastin, keratin and collagen – give the skin its structure and resilience.
Because peptides are amino acids and not proteins per se, they can penetrate the skin – unlike collagen, for example – when applied topically. There is a limit to the size of a particle to be absorbed by the stratum corneum – which is the top layer of our skin, the epidermis – and then used in a biological way in the skin. Different lengths and arrangements of these tiny amino acid chains result in different types of peptides being created. And although they all communicate with our skin cells, not all of them convey their messages identically.
How do you get more peptides into your skin?
When it comes to improving the skin, we recommend getting peptides from skin care products. Pay attention to the formulation of the product: the stability of the ingredients and the ability to penetrate the skin barrier. This is where an appointment with the skin specialist may be important. NB! Most cheap products have poor stability and do not penetrate the skin well
Choosing the right type of product can also help a lot. There is little point in choosing a peptide-enriched cleanser as you rinse it straight from the skin. Choose a peptide cream or even better a peptide serum. Copper peptides help produce collagen, but also maintain the collagen produced and strengthen existing collagen. Once you have found the right peptide cream or serum, apply it to clean skin twice a day before applying your makeup and SPF.
What types of peptides are used in cosmetics?
The main peptides used in skin care can be divided into a few categories (signal, carrier, enzyme inhibitor and neurotransmitter inhibitor), and depend on how they work.
Signal Peptides
Signal peptides activate mechanisms that influence wound healing. This in turn activates fibroblasts in response to broken chains of elastin and collagen. These types of peptides trick your skin cells into believing that there has been trauma. Your body then enters the recovery phase and activates the production of elastin and collagen - resulting in firmer, fuller skin.
Copper Peptides
Copper Peptides zoals van Medik8 zijn de meest voorkomende soort dragerpeptiden, die bijdragen aan de afgifte van sporenmineralen aan de huid. Koper helpt in het bijzonder “bij de actieve wondgenezing”, wat op zijn beurt de collageenproductie bevordert. Er zijn ook bewijzen dat koperpeptiden een antioxiderende werking hebben, hetgeen betekent dat ze helpen huidbeschadigende vrije radicalen onschadelijk te maken.
Enzyme inhibitory peptides
Enzyme inhibitor peptides are perhaps the most advanced: They work on the enzymes in your body that break down collagen over time. For most of us, this starts happening around the age of 20.
Neurotransmitter inhibitory peptides
Finally, neurotransmitter inhibitory peptides block the release of some chemical messengers that help muscles contract, thus producing a muscle relaxing effect theoretically similar to that of botulinum toxin. Botulinum toxin is, as is known, the scientific name for Botox. But to compete with an injection, a superficial cream or serum must penetrate the epidermis, dermis and fat layer to actually relax the muscle. And while we know that peptides are small enough to penetrate the top layer of our skin, more scientific research is needed to develop neurotransmitter-inhibiting peptides that can penetrate even deeper.
Mijn favoriete peptides serum
Als ik één antia-ging serum moet aanraden waar je écht resultaat van ziet, dan is het 
Medik8 Liquid Peptides Advanced
Dit is geen standaard peptide serum, maar een anti-aging serum met maar liefst 13 verschillende peptides. De formule werkt zichtbaar op huidstructuur, stevigheid en fijne lijntjes — zonder zwaar of irriterend te zijn.
- Laat de huid gladder en frisser ogen
- Ondersteunt stevigheid en elasticiteit
- Licht, snel absorberend en perfect in elke routine
Ik gebruik deze zelf dagelijks. Dit is zo’n product dat je routine simpeler maakt, maar je huid juist beter laat werken.
Vraag en antwoord peptides
According to dermatologists and skin care experts, peptides in skin care help prevent signs of premature aging and keep the skin soft, supple and youthful.
Peptides are proteins. Proteins are the building blocks of our skin and our skin needs them to remain firm and intact. As we age, the bonds between these proteins loosen, causing us to lose firmness and elasticity. Peptides in skin care help hold these bonds together, but remember that peptides need other ingredients to maximize their benefits, such as antioxidants.
You apply the product with the smaller molecules first. If Peptides are used in cream form, Retinol serums or other serums are usually applied first. Cream always comes after the serum!
Peptides work perfectly together with other anti-aging ingredients for the skin such as retinol, vitamin C and niacinamide.
Hyperpigmentation occurs when areas of the skin produce too much melanin, or pigment. This is a common problem for many women and men. Certain peptides can help brighten and even skin tone affected by pigmentation problems. But tackling hyperpigmentation is not possible without being treated, read more about this treat pigment spots
When looking for peptides in skin care products, look for words that end with “peptide” or start with “palmitoyl.” You will also see prefixes like -di, -tri, -hexa, -oligo, etc. to indicate how many amino acids the peptide consists of.
Retinol helps to accelerate cell renewal, Petiden improves, among other things, collagen and hyaluronic acid in the skin. There is not one better, they do something different in the skin.
Peptides do not cause irritation, redness or dryness of the skin and are therefore safe to use on all skin types. However, potential users should be aware that peptide skin care products may contain other ingredients that may cause irritation or inflammation.
Supplements such as Laviesage Skin Boost & Lift contain collagen–peptides (we call this hydrolyzed collagen). This is collagen, but then broken down into different amino acids. This allows our body to absorb it better and faster.
For all skin types
Around the age of 25, collagen decreases by approximately 1% every year. Collagen also deteriorates in quality as you get older. So it is good to think early on about supporting your collagen levels through: peptides to prevent premature skin aging.
