What are peptides, anyways?

Peptides 101

Embark on a journey into the fascinating world of peptides – the unsung heroes of skincare. So what are peptides? Peptides are compounds composed of linked amino acids, the building blocks of proteins. As essential components of our skin, they play a vital role in maintaining structure, firmness, and overall skin function. The building blocks for collagen and elastin fibers, crucial for tissue firmness and elasticity. However, despite being natural to the skin, stabilizing and delivering peptides in cosmetic applications can be challenging. Scientists have developed peptides that effectively penetrate the skin's surface, providing targeted benefits for various skincare concerns.

How Peptides Work in Skincare

The number of amino acids in a peptide defines its type – di-peptide (2 peptides), tri-peptide (3 peptides), and beyond. Tripeptides are a skincare powerhouse because of their ability to enhance skin cell renewal and regenerate collagen; especially in combating signs of aging on delicate areas like the neck. As we age, collagen production diminishes, and the skin's natural repair processes slow down. Applying peptides to the skin triggers a healing response, stimulating collagen production and restoring a healthy skin barrier. With consistent use, they contribute to smoother fine lines, improved elasticity, and overall skin rejuvenation.  

Different Types of Peptides

  1. Neurotransmitter Peptides: Found in Botox and topical treatments like Argireline, they relax facial muscles, reducing wrinkles.


  1. Signal Peptides: Stimulate collagen, elastin, and structure protein production, promoting firmer and fuller skin.

  1. Carrier Peptides: Deliver trace elements like copper and magnesium, enhancing collagen production and skin firmness.

  1. Enzyme-Inhibitor Peptides: Slow down the natural breakdown of collagen, retaining more collagen and preventing pigmentation.

Incorporating Peptides into Your Skincare Routine

Selecting the right peptide product can be daunting with the plethora of options available. Consider the form of the product for prolonged skin contact. Peptides work well with ingredients like vitamin C, niacinamide, antioxidants, and hyaluronic acids. Check the product label for peptides listed close to the top of the ingredient list or identified as "palmitoyl." Luckily, we already have the best option for you:

XEP 30 Serum: The Ultimate Peptide Serum

Erasa's XEP 30 Serum features a biomimetic peptide, X50 Myocept, which replicates the wrinkle-erasing and anti-aging properties of natural compounds. This exclusive delivery system directs neuro-peptides to skin cells, relaxing lines and wrinkles. Argireline, an acetyl hexapeptide-3, enhances the serum's effectiveness by gently relaxing muscles, giving the ultimate “botox-in-a-bottle” effect.
