Signal Restore™ Copper Peptides 1% Serum
How does it work?
How does it work?
Your skin sags when it loses collagen. Our copper peptide (GHK-Cu) sinks in and tells your skin to make its own collagen again, so it works on the sagging, not just the surface.
Is it right for sensitive skin?
Is it right for sensitive skin?
Yes. No fragrance, gentle enough for daily use, even if retinol usually burns you.
How do I use it?
How do I use it?
Put 3 to 4 drops on clean skin, morning and night, before your moisturizer. That's it. No sting, no downtime.

Real Renascent Users, Real Results.
Firmer, lifted skin, rebuilt from deep down
It tells your skin to rebuild its own collagen, the deep support that holds your face up. Gentle, made for skin over 40, and built to last.
Retinol only works on the surface, forcing your skin to peel. Too harsh for sensitive skin.
Confidence speaks for itself
My own face, back
"My face FINALLY goes with the rest of me!! I worked so hard for this body and then my face just deflated on me, all hollow and tired looking, it honestly wrecked me. Renascent gave me back some of that softness in my cheeks and now they actually match. Ladies, I didn't realize how much it was bugging me until it stopped."
I look like me again
"I feel like myself again, and honestly I never thought I'd get to say that. My face dropped so fast last year that I started dimming the lights at night so I wouldn't catch my own reflection, how sad is that. A couple months with Renascent and my jaw looks firmer, but it's recognizing myself again that gets me. I actually teared up."
I stay in the photo now
"I let my daughter keep a photo of me last weekend!! Two whole years I've been the one ducking out of every picture, or making everyone delete them, because I looked fine in the mirror and like a straight up GOBLIN on camera. My jaw looks firmer in photos now so I stayed in the shot. Ladies, you have no idea what that does for you."
I did everything right
"Honestly did not expect to be writing a good review. I've done EVERYTHING by the book, ten years of tretinoin, SPF 50 daily, and my lower face dropped anyway, so I was done trusting products. Renascent is the first one that gave me actual firmness and not just an hour of hydration. It's not instant and my skin purged a little at first, I'll be real. Four stars for now, I'll report back after month three."
Cancelled my consult
"I cancelled my facelift consult and I'm still in shock, honestly!! I went in for a little filler and got told that at 43 I need a lower facelift?! Deposit already paid and everything. I tried a plain copper peptide serum first out of pure stubbornness, Renascent, morning and night. Two months later my esthetician stops and asks what I changed because my jaw looked tighter. I saved myself thousands."
My makeup sits again
"My makeup finally goes on like it used to, and that's the thing I notice every single morning!! It had gotten to where foundation just sank into everything and I had to relearn my whole routine at my age. I got Renascent for the firmness and this was the happy surprise. Skin looks firmer and plumper too. So so happy."
The Science Behind the Firmness
1% Copper Tripeptide-1 (GHK-Cu)
A copper peptide small enough to reach deeper skin, where it signals your cells to rebuild collagen and elastin. A full 1%, and gentle on sensitive skin.
Acetyl Hexapeptide-8
The peptide behind expression-line serums. It helps soften the look of lines around the eyes and mouth, without irritating the skin.
Glycerin
A proven humectant that draws water into the skin for an instant plumper, smoother feel, and helps the peptides absorb.
Arginine
An amino acid that supports the skin's own repair and keeps the barrier calm, so the formula stays gentle enough for daily use.
Benefits That Build Over Time
Real firmness takes time. Each week builds on the last, working on the support your skin lost, not just the surface.
Skin Drinks It In
The serum sinks in instead of sitting on top. Your skin feels softer and calmer, and that dull, tired look starts to lift. First glow.
Bounce Comes Back
Skin feels smoother and a little more plump. Fine lines start to blur, your cheeks feel bouncier, and makeup sits better than it has in a while.
You Feel It Firm Up
The copper peptide is building now. Your cheeks feel denser and more supported, less like they're sliding. It's subtle, but your skin holds better than it did.
Now Others See It
This is when it shows. Your jawline looks more defined, your face looks lifted and fresher, and someone asks what you've changed. You look like yourself again, and you feel it.

Common Questions About Renascent
Most creams just sit on top of your skin, so they hydrate but never reach the sagging, which starts deeper down. Collagen itself is also way too big to sink in. GHK-Cu is tiny, so it actually gets in and tells your skin to rebuild its own firmness.
Retinol works by irritating the surface of your skin to speed up turnover, which is why it stings and peels for a lot of people. This has no retinol, it works deeper down on firmness, without the sting.
A full 1% GHK-Cu, and we print it right on the label. That’s a real, working dose, not a tiny amount added just so it can go on the ingredient list.
Put 3 to 4 drops on clean skin, morning and night, before your moisturizer. That’s the whole routine.
Yes. If you use retinol, keep it for nighttime and use this in the morning. If you use pure vitamin C, use it at a different time of day, since it can clash with copper peptides.
Yes, that’s exactly who it’s made for. There’s no retinol, no fragrance, and no hormones, so it’s gentle enough to use every day.
A few people get a short adjustment period in the first days as their skin gets used to the peptide, then it settles. If your skin is reactive, start every other day and work up to daily.
Yes. It’s built for the firmness loss that tends to hit around 40 and through menopause, when your skin makes less of what holds it up.
Copper peptides are gentle, but we always recommend checking with your doctor before using any active while pregnant or breastfeeding.
