Peptides for Skin: Why are They So Important?

Peptides for skin

Peptides are short chains of two or more amino acids that are the building units of proteins. They are the building blocks for collagen and elastin fibres. Our skin is made up of elastin fibres and peptides make the skin and tissues firm. Without the proteins that peptides make, we would also have brittle nails, dry hair, and wrinkled skin. Studies have found peptides to be beneficial towards skin, muscles, and maybe even weight. Peptides are present in every human cell and act as biological signals. If our body is deficient in peptides, it has difficulty in functioning. In our bodies, peptides serve as building blocks, hormones and even energy sources. Let us explore the importance of peptides for skin.

How do Peptides Affect Our Skin?

According to experts, humans lose 1% of their remaining collagen every year after they turn 30. The skin’s natural communication channels slow down as time passes. Peptides for skin are like signals that are sent to your body that help it to heal. The peptides signal the body to focus its repair efforts on the area that is injured. If your skin is showing symptoms of ageing, peptides might signal your skin to increase collagen and hyaluronic acid production. This restores the healthy barrier for our skin. Peptides have several beneficial qualities:

  1. Anti-ageing: Peptides stimulate collagen synthesis and trigger the production of elastin. Antimicrobial peptide causes the production of pigment in the skin. Synthetic AMPs are used for hyper-pigmentation, skin lightening, or reducing ‘age spots’.
  2. Improved skin barrier: Peptides that help the body fight bacteria also aid wound healing. They help strengthen the skin barrier against over-exfoliation, exposure, poor sleep, and exposure to pollution.
  3. Improved muscle growth: Peptides like creatine and collagen promote muscle development and produce growth hormones. This aids in muscle repair and growth.
  4. Improved skin elasticity: Peptides, such as elastin, aid the production of elastin fibres, which the skin is made up of. This makes the skin look firm and taut.
  5. Anti-inflammatory properties: Peptides contain antioxidants, which aid in soothing and calming the skin.

What are the Types of Peptides for Our Skin?

There are various types of peptides; some more effective on the skin than others. For example, signal peptides send messages to different parts of the skin to boost collagen, while neurotransmitter peptides block the release of certain chemicals. There are four types of peptides in skincare routine that are put into use.

1. Neurotransmitter Peptides 

They are found in injectables like Botox and topical treatments like Arigerline. Both of these work to relax facial muscles and help reduce wrinkles by doing so. A 2009 study found these peptides to be effective. They reduced certain wrinkle types by 30%.

2. Signal Peptides 

They are the most common and are known to be effective in skincare. These peptides stimulate the production of collagen, elastin, and other structural proteins. They make the skin appear fuller and firm.

3. Enzyme-Inhibitor Peptides 

They work by stopping the body’s process of losing collagen. They block the enzymes responsible for the breakdown of elastin production. Rice-derived peptides work to retain collagen, while peptides derived from soy proteins help prevent pigmentation. 

4. Carrier Peptides 

They deliver essential minerals to the skin so that certain processes like wound-healing can take place.

How Peptide Serums Work for Your Skin

If you’re a beginner with skincare, starting with a peptide serum for your face is a good idea. Peptides work well with serums as they tend to stay on your skin for longer periods of time. Serums have high concentrations of one or more peptides. It is better to be specific about your requirements when choosing a peptide product. The best peptide for skin depends on your skin type and your requirements. People with dry or sensitive skin should go with rehydrating formulas that can soothe the skin. These contain hyaluronic acid, ceramides, glycerin, and niacinamide. The market is flooded with peptide products and you may have a hard time picking one.

  1. Matrixyl 3000 is a peptide that is found in moisturisers. It repairs collagen, prevents photo-ageing, reduces fine lines and wrinkles, and restores firmness in the skin. 
  2. Palmitoyl tripeptides have anti-inflammatory and moisturising properties. They also reduce fine lines, wrinkles, and damage from exposure to sun and pollution.
  3. Copper peptides have intense moisturising properties. 
  4. Argireline is a synthetic peptide and it is used in many cosmetics. It is a topical botox. Argireline helps prevent skin sagging and reduce ageing signs.
  5. Tripeptides are incredibly efficient in softening the skin. They aid in decreasing discolouration and evening the skin tone.


Choose your skincare products very carefully. And if you have been diagnosed with any heart, liver or kidney condition, consult a doctor before you start using a new product. As for the peptides for skin, we hope you now have a fair idea about how they work in order to choose a skincare product right for you.
