What Are Peptide Serums & What Do They Do?

Let’s face it: Aging is a part of life. As we get older, the skin’s ability to repair itself slows down and collagen in our skin decreases over time, leading to wrinkles, loss of firmness and dull skin.

The aging process is no joke, but your skin care routine can actually help you defy it. Every day, it feels like there’s a trendy new skin care ingredient that’s said to change your skin for the better. Some ingredients are more hype than action, but others are really worth it — and peptides are an ingredient you won’t want to miss.

If you’ve been looking for an ingredient that will help make your skin firmer and more even, peptides might be just what you need. But before you rush out to grab the first product with “peptides” on the label, it’s important to know what they are — and whether they’re actually worth it.

What are collagen Peptides serum & What do they do?

Peptides are the building blocks of life. Everything we need to function is made up of peptides, from hormones to enzymes and even DNA. We use them every day and they play a role in every biological process that keeps us alive. Peptides are essential for keeping our skin beautiful and healthy. They play a role in collagen in the skin, elastin production and tissue firmness; which all contribute to our overall appearance.

Most of us lose collagen in our skin over time — which is to say, your skin’s appearance can change as we get older. Peptides are proteins that naturally occur in the skin, and they are part of what makes up collagen. Adding peptides can stimulate your skin to make more collagen and lead to firmer, younger-looking skin.

Peptides are a naturally occurring part of the human body — they’re involved in the production of collagen, which is what your skin needs more of as it ages. Peptides are amino acids that make up certain proteins in the skin. More specifically, collagen is made of three polypeptide chains, so adding peptides can stimulate your skin to make collagen.

Peptides are smaller pieces of a protein complex, meaning they're less likely to inflame the skin when used compared to larger proteins. Peptides can also control factors that contribute to skin tone, sensitivity and hormonal activity such as breakouts.

What are the different types of peptides?

There are a number of different types of peptides that are used in skin care products, each with their own specific purpose. Some act as antioxidants, while others work to even skin tone; others aid collagen or elastin production inside the skin. There are many types of peptides, but some are more effective than others. Carrier peptides deliver minerals to your skin to help collagen, while enzyme inhibitor peptides work to slow down the breakdown of collagen. Signal peptides send messages to different parts of the skin to promote collagen and elastin; neurotransmitter peptides block chemicals that cause muscle contraction in expression lines.

How collagen Peptides in SkinCare Work

Like coffee for your skin, our Collagen Serum is designed to help your body’s natural production of collagen and plump up your skin. But we make sure our peptides are absorbed ten times more effectively than other products, so you get all the benefits without feeling any irritation. We created this serum using the latest in anti-aging technology because we believe getting the best results means using high quality ingredients that make a real difference.

Introducing Dēpology's collagen peptide serum duo onto your skin in the form of a serum is probably the most effective way to fight signs of aging. Why? Because it tricks the skin into thinking there’s been an injury or wound, which helps enhance our collagen processes.

benefits of collagen building serum in skincare

  • Peptides can permeate the skin's outer layer, allowing them to sink in deeper rather than rest on top of it. Consider them messengers for the other cells. They deliver messages to the cells instructing them to generate collagen and elastin.

  • More elastic skin. In addition to collagen, peptides are found in elastin fibers, which are also proteins. These fibers give the skin a firmer and tauter appearance.

  • Relieves inflammation Peptides can aid in the reduction of inflammation, the restoration of damaged skin, and the evenness of skin tone.

  • Can help with acne outbreaks. Some peptides are antimicrobial, which means they can fight acne-causing bacteria.

  • Skin barrier improvement. The skin barrier is the body's first line of protection against germs, UV radiation, pollution, and other poisons. Excessive exfoliation, cigarette smoke and other pollutants, and even lack of sleep can all harm the skin barrier.
    Peptides aid in the formation of a stronger barrier.

  • Wrinkles have been reduced. Collagen can plump skin and lips. Wrinkles and fine lines will be less evident when the skin is firmer and plumper.

Peptides are frequently promoted as a miraculous treatment, with some claiming that they work as effectively as Botulinum Toxin. This is due to the fact that neurotransmitter peptides can temporarily inhibit molecules that trigger muscular contraction.

peptide-containing serum or moisturizer can result in tighter, younger-looking skin and possibly fewer breakouts.

Peptides are generally regarded as safe, and while they are a potential skin care component, further study on their effectiveness is required.
