There are many ingredients making rounds in the skincare industry. Hyaluronic acid, niacinamide and AHAs are a few favourites found on everyone’s shelf. However, there is one ingredient that has gone under the radar, but is now resurfacing – peptides.

Peptides have been a part of anti-aging skin products for years but lately they’ve had a resurgence as a result of the boom in skincare. They have come a long way and there’s plenty of research that supports their use in skincare.

In this blog, TABIIB takes a look at what they are, and why you should incorporate them in your skincare routine.

What Are Peptides?

Peptides are molecules made up of short chains of amino acids. Essentially, they are smaller versions of proteins. They are also easier for the body to absorb than proteins because they are smaller and more defragmented.

Peptides are an integral part of collagen. They send signals to your cells to produce more collagen, which is one of the major building blocks of your skin.

Collagen production decreases as you age. This is the reason why peptides are found in most anti-wrinkle, anti-aging formulations of skincare products.
Most products aim to increase the amount of collagen your cells produce with the ultimate goal being smoother, plumper, healthier skin.

What Are Their Benefits?

1. Improved skin barrier
The skin barrier is the body’s first line of defence against bacteria and germs. Usually, it starts losing its strength as you age. Additionally, external factors such as over-exfoliation and pollution also play a role. Peptides strengthen the skin barrier by stimulating collagen production.

2. Reduces wrinkles & fine lines
Peptides increase skin hydration and elasticity. This has shown to have a positive effect on skin health – noticeably on wrinkles and fine lines.

3. Tightens skin
Peptides in skincare products work to tighten skin as they stimulate collagen growth. GHK peptide functions to tighten loose skin, improve elasticity, and skin density.

4. Accelerates wound healing
Certain peptides have anti-microbial and anti-inflammatory properties. For this reason, the research around their wound healing potential is promising. 

Types Of Peptides

There are 3 different types of peptides used in skincare:

1. Carrier Peptides
There are two types of carrier peptides; copper and manganese.

Carrier peptides deliver trace minerals such as copper or manganese to where they’re needed in the skin. They’re important in promoting skin repair, restoration, and wound healing. They also improve skin texture and reduce scars.

2. Signal Peptides
These proteins are the ones that promote collagen growth. They are also able to protect the existing collagen and reduce pigmentation.

3. Neurotransmitter Peptides (Inhibitors)
Neurotransmitter peptides inhibit and interfere with our facial muscle movements. Essentially, they block communication between cells during muscle contraction and relaxation. These repeat movements are what cause wrinkles and fine lines. As a result, these proteins reduce wrinkle depth and soften lines.

How To Use Them In Skincare

Dermatologists recommend adding this active ingredient into your skincare routine through topical treatments. The most important thing to keep in mind is that peptides need supporting ingredients to help address all the needs of skin.

Peptides mimic a natural process that happens in your body every day. But the challenge is grouping the right amino acids and sequencing them in the right order. 

  • It’s important to pick the right form. For example: serums or moisturizers are recommended because they have prolonged contact with your skin. 
  • Choose your ingredients wisely. Peptides work well with niacinamide and hyaluronic acid, depending on your skin requirements.

The Bottom Line

Peptides can be a great addition to your skin care routine because they can address so many skin concerns. But as with all active ingredients, the best approach is to consult a dermatologist before making any significant changes to your skin care. You can book a consultation with a professional on TABIIB and get all the information you need for better skin health.
