Copper Peptides Before or After Retinol? Yes, There’s a Right Answer

by Yu-Jun Park 29 Apr 2024

Hey skinthusiast, welcome to the world of K-Beauty where all your skincare questions are answered in style! 

Today, we are diving into an important question that keeps popping up: 

Should you use copper peptides before or after retinol? 

It sounds like a mystery riddled with scientific terms, right? 

Well, buckle up, because by the end of this guide it will all make sense.

We promise.

Do you put peptides or retinol on first?

First and foremost, let's get this straight: the sequence of applying skincare ingredients is pivotal. 

You can own the best products, but if you're not applying them in the correct order, you might not reap the full benefits. 

And when it comes to peptides and retinol, you want all the benefits you can get. 

But, do you put peptides or retinol on first? 

Well, the consensus leans towards peptides first. 

There's a simple explanation for this. Usually, the rule of thumb is applying products from thinnest to thickest consistency. Peptides tend to be found in lighter serums (love those!) that can effortlessly slide into your skin cells and get busy. 

On the dance floor of your dermis, these peptides are like the life of the party. They stimulate collagen production and improve skin elasticity. Ready to revivify your skin, they need a red carpet entry to pull off their magic.

Retinol, on the other hand, loves to strut its stuff in more robust outfits - lotions and creams. These thicker formulations create a secure layer to lock in all the good stuff, including your favorite peptides. 

But here's an important note: retinol has a reputation. 

It is famously active and incredibly potent. It’s an enthralling part of your skincare soirée but it's also strong and has a tendency to irritate skin (rude!). Hence, it's generally better to let peptides take center stage first.

The application of peptides before retinol is likely to let their positive effects unfold effectively without the risk of retinol stealing the show and potentially causing an inflamed, irritated response.

Moreover, you’re likely already aware of the phenomena of “mixing crime” in the realm of skincare. There are certain products that just don’t get along. 

But peptides and retinol? They're more like Timon and Pumbaa than Capulet and Montague.

As we delve into some chemistry, you'll appreciate that copper peptides and retinol can co-exist without disrupting each other’s functions when applied in succession. Their compatibility leads to a productive synergistic effect, driving the limelight towards supple, youthful skin.

Which comes first, the chicken or the egg? That's up for debate. But the peptides or retinol question? Peptides come first - we got that. 

There you have it. By using peptides before retinol, you're allowing better absorption and effective work, creating a promising pathway toward your skincare goals. 

Is it better to use copper peptides day or night?

Well, dear reader, when it comes to when you should wield copper peptides in your skincare routine, methinks the answer might surprise you. 

But before we pop that proverbial question, let's dish out a bountiful refresher on the rhythms of your skin. 

Fact: your skin changes throughout the day. Daylight hours? Your skin's primary function is protection. Night-time hours? Ah, that's the skin repair and regeneration period. 

So, where do copper peptides fit in this 24-hour rhythm? 

Copper peptides encourage skin repair and regeneration. So logically, your mind might jump to the conclusion that night-time applications are king. 

But hold that thought! 

You see, copper peptides aren't nocturnal creatures. They don't only come out to play in the moonlight; they're effective day or night. 

However, bear in mind that during the day, your skin is in protect mode, a shield against naughty environmental elements. 

Incorporating copper peptides into your daytime routine could contribute extra resistance, somewhat like adding an extra knight to your skin's daytime protection army. Knight and day, you might say.

Now, let's chat about the interaction between copper peptides and your skin at night. 

While it's regenerating and repairing itself, applying copper peptides can support these processes. Imagine your skin as a construction site at night - copper peptides are like the helpful supervisor, ensuring the work progresses smoothly and effectively. 

“But what about my other delectable skincare ingredients?” you wonder. 

Ah, an excellent query! Copper peptides are friendly, sociable little molecules. They play well with others like hyaluronic acid and your moisturizers. 

However, here's the kicker - they may get into fisticuffs with acidic products like vitamin C.

If that's a vital part of your routine, it might be wiser to use copper peptides at night, away from their quarrelsome acidic counterparts. 

So, dear skincare aficionado, the answer isn't just cut and dried, day or night. It also depends on your unique skincare regimen. 

Our advice? Experiment, observe, and tweak. Apply copper peptides during the day and observe how your skin reacts. Try them at night and analyze any differences. 

It's a bit of skincare investigative work - you're a veritable Sherlock Holmes in an apron!

In conclusion, there's no hard-set rule stamped in copper (peptides). They're flexible, adaptable, and eager to serve, be it under the sun or moon. Understanding your skin's needs and reactions is the key to unlocking this puzzle. 

So, dear reader, go forth and unlock this skincare conundrum. Explore the world copper peptides have to offer, and find out how they best serve you, day or night. 

Happy sleuthing!

What should you not layer with copper peptides?

Rule one on the skincare playground—some ingredients just don't play well together. And in some cases, copper peptides can be like that finicky child who's very specific about their friends. 

So, let's delve into the rulebook to make sure your skincare routine won't turn into an aesthetic anarchy.

We've already established retinol and copper peptides as the skincare version of Batman and Robin. They complement each other beautifully. But what's the villain in this context?

Enter direct acids and vitamin C. 

Ever been to a party where two people just can't seem to get along? That's copper peptides and direct acids. 

Alpha hydroxy acids (AHAs), beta hydroxy acids (BHAs), and L-ascorbic acid (pure form of Vitamin C) can be a no-go zone when it comes to copper peptides.


Magic word: pH. 

Most direct acids have a low pH which isn't quite harmonious with the copper peptide's comfort zone. When acids enter the mix, the acidic environment can destabilize copper peptides, rendering them useless. 

In skincare terms, they get their wires crossed, their friendship fizzles, and the magic ceases.

Now, onto vitamin C.

Everyone loves a good glass of orange juice in the morning, right? 

But we’re talking skincare, not breakfast. In this context, vitamin C (especially in its pure form) doesn't pair well with copper peptides. The reason is the same—copper peptides need a specific pH to maintain their stability and efficacy.

This isn't to say copper peptides and vitamin C are bitter enemies, but they need to keep a respectful distance for your skin to reap the benefits. 

Now, you may be thinking, "That's easy. I'll just use my vitamin C serum in the morning and copper peptides at night." 

If only it were that simple, skincare enthusiast! 

When it comes to using copper peptides and vitamin C, even splitting AM/PM might not be enough. They’re like that troublesome couple that needs a few days off to cool down before having a constructive conversation. 

So, consider alternating them every other day or on different days of the week.

Same goes for direct acids, by the way. A different schedule is ideal for achieving those radiant #skingoals, without stepping on any skincare toes.

And remember—everyone's skin is unique, so no skincare matchup is a guaranteed slam dunk. Listen to your skin, and adjust your routine, as needed.

This isn't to tangle you in the web of skincare dos and don'ts, but to ensure your carefully curated products are working hand in hand. 

Explore, experiment, and enjoy the journey to glowing skin.

1, 2, 3...ready, set, glow!

How long to wait between peptides and retinol?

Alright, here's the real pixie dust - the deets on when to send retinol and peptides in the ring. 

After retinol has taken center stage, hold your applause and give your skin a good 5 to 10 minutes to bask in its glory. 

Now cue the grand entrance for copper peptides and let the second act begin.

Remember, think of it as a synchronized dance, not a wrestling match. Don't rush. We're not racing here, we're creating skincare magic!
