Copper Peptides Anti-Aging Benefits
Copper peptides, and more specifically, GHK-Cu, have impressive anti-aging benefits.
You actually have GHK-Cu in your blood plasma right now. It’s just a matter of how much, as this copper peptide becomes depleted the older you get. Given the connection between GHK-Cu, collagen, and elastin, it’s no wonder the visible signs of aging include:
- Loss of firmness
- Wrinkles and fine lines
- Slower healing
- Less radiance
The good news is the copper peptides anti-aging benefits are well within reach. You can add a GHK-Cu face serum to your regimen and start offsetting the effects of getting older. Learn more below!
Key Takeaways
- GHK-Cu is a naturally occurring copper peptide that declines with age.
- Scientists have been studying GHK-Cu since the 1970s, and we know a lot about what it can do for the skin and hair now.
- Copper peptides are safe for most people and compatible with existing skincare routines.
- It takes 6-8 weeks before any visible changes become apparent for most people.
- PLU Laboratories has a full copper peptide serum collection whether you’re noticing the signs of aging in your skin or hair (or both!).
Overview of Copper Peptides
When we talk about the copper peptides anti-aging benefits, it’s really GHK-Cu that we’re focusing on. This stands for glycyl-L-histidyl-L-lysine copper(II). It’s just three amino acids bound to a copper ion.
Your body makes GHK-Cu on its own. It circulates in blood plasma, saliva, and urine. We first became aware of it in the 1970s when Dr. Loren Pickart isolated it from human albumin. Since then, more than 100 papers have been published on the copper peptide’s biological activity.
The reason anyone trying to age more gracefully should be interested in copper peptides, though, is because GHK-Cu levels peak in your 20s. They gradually decline all the way into your 60s. It’s no wonder you see changes in skin firmness and texture.
GHK-Cu is a signal peptide. That just means it helps facilitate the processes that are already supposed to happen in the body. That includes collagen production and the skin’s renewal cycle. That’s where a lot of the conversation on copper peptides for anti-aging comes into frame.
The Copper Peptides Anti-Aging Benefits
We have an entire guide talking about the copper peptides skin benefits because they are so plentiful. But as it pertains to the anti-aging potential of copper peptides, here’s what we know from the research:
- Firmness: GHK-Cu supports collagen and elastin signaling, essentially encouraging the body to make more of these vital structural proteins.1 Both of them can become less abundant with age, leading to saggy skin.
- Fine lines: Studies have shown that GHK-Cu can help streamline the skin’s natural renewal process, pushing fresh skin to the surface to help fill in fine lines so they become less noticeable.
- Texture and tone: A lot of people who try copper peptides say their skin feels smoother and looks more even - as quickly as the first few weeks of use!
- Skin thickness: Thinning skin is one of the telltale signs of aging, but copper peptides can help thanks to their ability to modulate genes tied to dermal structure and density.
Whether you’re drawn to GHK-Cu for loose skin or your complexion overall, part of the appeal is how gentle copper peptides are compared to alternative skincare solutions. Board-certified dermatologist Dr. Blair Murphy-Rose says, “I have recommended copper peptides to patients, especially those looking for non-retinoid products.”2
Setting Expectations With Copper Peptides
The sooner you start with your copper peptides anti-aging protocol, the better. Because they DO NOT work overnight. In fact, a lot of people use them for 6-8 weeks before seeing meaningful signs of progress.
You need to set your expectations. The skin’s natural renewal cycle takes anywhere between 4-6 weeks, and hair growth phases are even longer. The transformation you’re envisioning may be possible, but only if you stick with the routine long enough and stay consistent. We’ve found that the results are cumulative. Meaning, skipping days sets you back a lot more than you might think. And doubling up after missing a day will not make up the difference.
How to Tap into the Anti-Aging Benefits of Copper Peptides
The first thing you need to do is secure the best copper peptide serum, right here at PLU Laboratories. We imagine you’re more interested in the skincare benefits of GHK-Cu if you’re exploring its anti-aging potential, so start with the Face Tonic. It has 1% GHK-Cu with Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 for more well-rounded support.
What’s not in the formula is any fluff or filler. Just 6 ingredients in total. No dye, fragrance, alcohol, or botanical extracts that only crowd the peptides and get in the way.
Actually using copper peptides for anti-aging is very easy. Just place a few drops on your face or fingertips and massage it in. Do this every single day, and stick with it for at least 8 weeks before drawing any conclusions about whether or not it’s working.
You can decide what’s easier to stick with - morning or night application. If you are layering with other ingredients, make sure you apply in order of lightest to heaviest. We recommend GHK-Cu after cleansing and toning, but before moisturizer and SPF.
Other Ways to Age More Gracefully
Copper peptides are just one way you can slow down the effects of Father Time. The best thing you can do to prevent the signs of aging from appearing too early is daily sun protection. SPF is non-negotiable anytime you head outside. Even on cloudy days.
Hydration is equally important. Both on the skin (we love hyaluronic acid) and from within. Drink plenty of water every single day. You can also layer niacinamide in your skincare routine. Vitamin C is the other ingredient we see good results from as far as brightening goes.
