Spotlight: What are Peptides and What Do They Do?

Let's dive into the world of peptides. You've probably seen them on your favourite serums and creams, but what are these little guys, and what do they actually do to our skin?

What are Peptides?

Imagine your skin is a bustling construction site. It needs workers, materials, and a blueprint to stay strong and healthy. That's where peptides come in! They're basically short chains of amino acids, the building blocks of proteins like collagen, elastin, and keratin.

What Do Peptides Actually Do?

Collagen Boosters. Collagen is the scaffolding that keeps your skin firm and plump. As we age, collagen production slows down, leading to wrinkles and sagging. Peptides step in and say, "Hey, skin cells! Time to make more collagen!" Some peptides, like those called "signal peptides," tell your skin to produce more of this vital protein.

Elastin Enhancers. Think of elastin as the bouncy springs. Elastin is what gives your skin its bounce and flexibility. Peptides can also stimulate elastin production, helping your skin snap back into place.

Wound Healing and Barrier Repair. They are your skin's little repair crew who patch up any damage. They can help repair your skin's barrier, which is essential for keeping moisture in and irritants out.

Wrinkle Reduction. They are like the skin's personal smoothers. By boosting collagen and elastin, peptides can help smooth out fine lines and wrinkles. Some peptides, like "neurotransmitter-inhibiting peptides," can even temporarily relax facial muscles, similar to how Botox works (but much milder!).

Fades Dark Spots. Some peptides can help regulate melanin production, which can help to fade dark spots and even out skin tone.

If you’re wanting to add this superstar ingredient into your skincare routine, you'll find peptides in a variety of products, including:

Serums: These are often the most potent peptide-packed products.   

Creams: Moisturisers with peptides can help hydrate and improve skin texture.   

Eye creams: Peptides can target fine lines and wrinkles around the delicate eye area.

Peptides work best when applied after cleansing and toning but before heavier creams.

Remember: Like any good skincare ingredient, peptides take time to work their magic. Don't expect overnight miracles. Peptides often play well with other ingredients like hyaluronic acid and antioxidants, such as Vitamin C. They're a fantastic addition to any skincare routine, especially if you're concerned about signs of aging (age spots, wrinkles, sagging).

So, go ahead and add some peptide power to your skincare arsenal! Your skin will thank you.
