What are peptides – and why are they important for skincare?


Chances are you’ve heard this word floating around in the world of skincare, but aren’t too sure what it means, or why you need to make them a part of your routine.

While you might not completely understand what peptides are (yet!) or how they work, they are an essential addition to many effective products that combat against common signs of maturing skin, such as:

  • Fine lines
  • Thinning skin
  • Lack of buoyancy or suppleness
  • Dryness

So how exactly do peptides help with these common skin concerns? Let’s take a look!

What are Peptides?

In its most basic explanation, peptides are amino acid chains that serve as building blocks for protein in the body.

Protein is a major part of what makes up the skin, tissues and organs throughout the body. Collagen is one such vital protein – in fact, between 75 and 80 percent of the skin is made up of collagen. Peptides actually help produce collagen, a protein crucial to keeping skin healthy and supple. The natural aging process can decrease the body’s ability to maintain ample collagen levels. This can lead to the development of fine lines, loss of skin firmness and thinning skin. Sound hopeless? It’s not. Keep reading.

Peptides and Skincare

One way to fight back against the natural decline of collagen is to choose skincare products that are packed full of peptides and other skin-friendly ingredients. 

Essentially, when you apply peptides to the skin topically, you’re giving cells the hint that it needs to do better in the collagen production department – thus prompting skin cells to develop collagen for areas that need it the most.

How to Use Peptides in a Skincare Routine

With Sanitas Skincare, incorporating peptides into a skincare routine is as simple as adding a serum with your daily moisturizer, or adding an eye cream to help reduce fine lines that typically develop around the eye’s thin and delicate skin.

PeptiDerm Firming Serum contains a multiplex of peptides, all of which work together to increase the skin’s elasticity and firmness. In addition to reducing the appearance of fine lines, the Firming Serum also protects the skin against environmental factors that speed up the aging process! Simply smooth a dropper full of serum to the entire face, neck and decollete, then follow up with your favorite hydrating moisturizer.

For those with mature skin or if you find that your skin is losing firmness, PeptiDerm Moisturizing Cream is packed full of beneficial peptides and other hydrating ingredients to provide skin a healthy and supple texture. This moisturizing cream also infuses plenty of moisture and oxygen to fight back against dryness and give your skin a radiant glow.
