What Do Peptides Do For Your Skin?

Anti-aging products are ruling the beauty scene, with new and diverse ingredients popping up in different products claiming to give you much younger skin. Peptides have been a fascinating skin ingredient in the anti-aging business for years. However, it’s been getting even more recognition in the recent years.

The reason? Peptides are backed by science and have been proven to delay the aging process. We are here to unravel the anti-aging secret of Peptides and how they can give you much younger looking skin.


Peptides are short strands of amino acids, that forms the building blocks of proteins. These proteins include collagen, elastin and keratin that work together to keep your skin firm and supple.

When you apply peptides to your skin, they send signals to your skin cells to boost the collagen level. This is very significant as collagen is what keeps the skin from sagging.

The level of collagen diminishes with age, resulting in a loss of elasticity and more wrinkles. Excess exposure to sunlight also contributes to depleting level of collagen in the skin. Because peptides are responsible for generating more collagen, they reduce the appearance of fine lines and wrinkles and make your skin look younger than ever.

For this reason, peptides have become a vital anti-aging ingredient that combats the tell-tale signs of aging. Keeping this in mind, many K-beauty brands incorporate this ingredient into their anti-aging skincare range.


There are hundreds of peptides out there. With ongoing research, scientists are discovering newer peptides time and again. Some common types of peptides used in skincare are as follows:


This is the type of peptide that,when in skincare products, signals the cells to increase the production of collagen level. Thus, your skin is able to stave off fine lines and wrinkles and the result, is a younger and plump skin. An example of signalling peptides used in skincare products is called the Palmitoyl Tripeptide-5.


 Neuropeptides work by relaxing the facial muscles and help to achieve a smooth complexion by reversing the aging lines. The effect of using this peptide on skin has been shown to mimic the effects of non-invasive procedures like botox injections. It comes under the trademark name called Argirelene.


People often rave about copper peptides for their role in anti-aging skincare routine. Copper molecules are tiny by nature, which enables them to penetrate the skin layers and repair the signs of ageing. There are reports of copper being toxic, but there is no proof of its topical use being toxic in any way. Copper peptide, in combination with peptides or antioxidants, deliver great effects on skin.


No matter what skin type you have, peptides can be beneficial for your skin. In fact, researches on peptides in skincare have indicated how they can be used to correct wrinkles, skin discolorations, dull skin and loss of elasticity.

Peptides are the key elements that give you younger looking skin. When your skin is losing collagen, your skin suffers leading to fine lines and wrinkles, loss of elasticity, poor complexion, dry skin, uneven skin tones and many more. In this condition, your best bet is adding peptides to your skincare routine. Peptides come to your rescue as they penetrate the skin barrier and direct the cells to make more collagen, giving you a firmer skin.

Peptides come in different formulations like creams and serums. Creams are on the heavier side, preventing the ingredient to penetrate into the skin to yield its best results. While serum forms are more effective as the skin can absorb the ingredient better. This allows the peptide to work more efficiently to give you a plump skin.

It is noteworthy that using peptides on your skin may not turn the tide overnight. It takes time to show its results, so you need to be patient and consistent in your peptide use. You also need to remember that using peptides on the skin cannot replace the kind of effects some cosmetic procedures may bring. On the flipside, skincare products that contain peptides come at a hefty price.


Science backs up peptides and what it does, so there is no doubt about how they can work to reverse the aging process. But we also need to remember that peptides alone cannot combat against the ageing battle. You must use peptides in combination with other skin elements to fight the signs of ageing.

Create a robust anti-ageing skincare regime that includes hydrating agents, antioxidants, and sunscreen along with your daily dose of peptides. With a formidable force that counters the signs of aging, you can not only enjoy a younger skin but also a healthy, radiant complexion.
