What Do Peptides Do For Skin? Everything You Need To Know About Peptides In Skincare
Peptides are one of the buzziest ingredients in skincare. But while they're enjoying some well-deserved time in the spotlight, these powerful collagen-boosters are far from new.
Peptides are a tried-and-true skincare ingredient renowned for their anti-aging abilities. Keep reading to learn how peptides work in skincare, and how to incorporate them into your routine.
What are peptides?
“Peptides are amino acids that signal your skin to increase collagen production, leading to a healthier skin barrier and plumper, more bouncy appearance,” says Biossance Director of Product Marketing + Strategy Celeste Schreier.
You may remember from science class that amino acids are the building blocks of proteins. Unlike complete proteins such as collagen, these tiny fragments are able to penetrate the top layer of skin, making them an ideal ingredient to include in skincare formulas.
How are peptides beneficial?
Peptides are a unique anti-aging ingredient because they don’t simply mask wrinkles, they signal the skin to produce more collagen. Because our collagen production naturally decreases as we get older, giving it a boost creates visible changes in the skin including:
- Reducing the appearance of fine lines and wrinkles
- Strengthening the skin barrier
- Locking in hydration
- Firming the skin
- Making skin smoother
Different Kinds Of Peptides
There are three types of peptides most commonly used in skincare:
- Signal Peptides - Their mission in life is to promote collagen production, plain and simple.
- Carrier Peptides - These amino acids stabilize and deliver copper to certain enzymes, which then use it to grow collagen and elastin.
- Nerve-inhibiting Peptides - Almost like a topical Botox, these peptides inhibit nerve signals to soften fine lines and wrinkles
What are copper peptides and how are they different?
If peptides were celebrities, copper peptides would be Meryl Streep. With decades of data-driven success, copper peptides bring a special skillset to your skincare products.
“Copper peptides are unique because they act as antioxidants while also stimulating collagen and elastin production in the skin,” says Celeste.
Their antioxidant properties enable copper peptides to fight free radicals, protecting skin from damaging UV rays and pollution which can cause more signs of aging. So not only do they improve the look of fine lines and wrinkles you already have, they help prevent more from forming.
How to incorporate peptides into your routine
“Peptides are great for all skin types, especially for those who are dry to mature and noticing increased fine lines and wrinkles and a loss in firmness,” says Celeste. “Peptides are safe and effective for daily use, and work great in tandem with other actives except for exfoliating acids such as AHA’s.”
If you’re going to combine your peptides with other actives, we recommend products containing Vitamin C such as our
