Active Ingredients: Peptides

All you need to know about Peptides!

Skincare ingredients are getting more complex by the minute. Natural ingredients are easy to understand and comprehend but synthetic ingredients with scientific names are a whole different story. Just trying to pronounce them correctly is considered a feat. With technologies and formulation evolving, newer ingredients increase but that doesn’t mean all of them will work for your skin. This doesn’t mean you have to go out there and try everything. What’s important is knowing your skin and its needs, understanding the benefits of ingredients and pairing that knowledge up to find the ingredient that ticks those boxes.

Now, our ingredient of the day is Peptides, also known as polypeptides. Peptides are made up off short amino acids that build up much needed proteins by the skin. Peptides are often said and boasted to help increase collagen production. This is because collagen is comprised of 3 polypeptide chains.

There are hundred different kinds of peptides but not all of them function and benefit the skin the same way.

  • Carrier peptides: Works to deliver trace minerals to the skin to increase collagen.
  • Enzyme inhibitor peptides: Works to slow down the degradation of collagen.
  • Signal peptides: Sends signals to the skin to enhance collagen, elastin and other proteins, production.
  • Neurotransmitter peptides: Inhibits the muscle contraction that causes fine lines and wrinkles. Often touted to have “Botox-like” effects.

But there are 2 types that are more commonly seen and used in skincare and they both have different functions.

  • Tetrapeptides: Made up of 6 amino acids. Brightening benefits.
  • Hexapeptides: Made up of 4 amino acids. Boost skin firmness and elasticity.



Firms the skin

  • Unlike typical collagen-infused skincare products, peptides work better as it can penetrate deeper into the skin, into the cellular level and signaling the cells to produce more collagen. Resulting in less wrinkles, fine lines and overall plumper looking skin.

Evens out skin tone and complexion

  • Peptides help with evening out discolored skin tone and rough skin texture, contributing to brighter and smoother skin.

Strengthens skin barrier

  • Peptides acts as messengers to tell the cells to produce more collagen. By doing so, it also enhances the skin’s protective barrier. Protecting against UV rays, pollution and harmful chemicals.

Improves skin’s hydration

  • The lack of collagen production in the skin often leads to dehydration, with more collagen also means increased moisture levels.

Repairs damaged skin

  • Peptides possess anti-inflammatory properties that ease inflammation and repair damaged skin.


What to note?

  • Peptides are still considered to be fairly new in the skincare market. And although it is said to have anti-aging benefits, there isn’t enough research to prove its efficacy against powerhouse ingredients like retinol/retinoids and hydroxy acids.
  • Peptides are relatively compatible with most ingredients, the only ingredient to stay clear from is AHAs as the low pH level can decrease the effectiveness of peptides.
  • Always conduct a patch test prior to application.
