Glow GHK-Cu Copper Peptide Serum
Lightweight yet potent Copper Peptide serum for skin to look firmer, smoother, and younger over time.
GHK-Cu is one of the most researched anti-aging peptides there is, and independent published studies back what people buy it for: a reduced look of fine lines and wrinkles and a more lifted appearance.
It hydrates deeply, stays gentle on sensitive skin, and takes 2 to 4 drops a day.

What to expect
Right away: light hydration, no sting, no smell, nothing sitting on your skin. Over the first few weeks: smoother, more refreshed-looking skin, and fine lines start to look softer. Keep it up daily and you get what GHK-Cu is heavily researched for, the look of firmer, tighter, younger skin. That research is independent and published. We didn't run it ourselves, that's the point.
It's a serum, not a magic trick. Use it every day and give it a few weeks. If it doesn't work for you, you have 30 days for a full refund, even after you've opened it and used it.
How to use it
Cleanse with Fresh Start, then press 2 to 4 drops of Glow into your face and neck and let it absorb. It's gentle enough to use under and around the eyes. Lock it in with Damage Control. Using it in the morning? Finish with SPF.
Two pairing notes. Don't layer Glow with Vitamin C in the same application, that combo can temporarily discolor skin. If you're using Radiance Surge, keep them at opposite ends of the day. Retinol is fine: Glow in the morning, retinol at night, or alternate nights.
What's in the kit
Every bottle of Glow is 50 mL (1.69 fl oz), a one-month supply used daily. Inside the formula: Copper Tripeptide-1 (GHK-Cu) at 0.2%, a peptide support complex, and sodium hyaluronate for hydration.
The bigger the supply, the more we throw in free. The 3-month supply adds a free Fresh Start cleanser and a free Damage Control moisturizer, so you're running the full routine. The 6-month supply doubles those and adds a free Face Massager, a free full-size Vitamin C serum, and a free Face Sculptor, plus free shipping.
The MAXXING standard
Every ingredient is here because independent, published research says it does something, and it's dosed at the level that research actually used. The copper peptide for firmness and fine lines, the ceramides for the barrier, the glycerin for hydration, all of it. In one published comparison, copper peptide raised procollagen in more people than vitamin C or even tretinoin did. We didn't run that study, that's the point.
No filler, no fragrance, no proprietary blend hiding a sprinkle of the good stuff. Rated Excellent 4.8/5 on Trustpilot, and the before-and-afters are from real buyers we never paid.

Same Face, No Filter
No flattering light, no makeup tricks. Daily Glow is the only thing that changed between these photos. Drag the line and look at the jawline first.
Firmer, smoother-looking skin that built up over weeks, not overnight.
We gave the other guys a few wins.
Every brand's comparison chart has them winning all five rows. That's why they're worthless. So here's an honest one. Where the other guys actually beat us, we said so. You decide if the things they're winning are the things that matter.

That's the Whole Point.
Every brand waves around its own "clinical trial." We're not going to insult you like that.

Frequently Asked Questions
What is Maxxing?
Maxxing makes skincare, supplements, and tools for people who want results without a complicated routine. Copper peptide and vitamin C serums, collagen and creatine, jawline tools. Everything is here because the ingredient actually does something, not because it rounds out a shelf.
What makes Maxxing different?
Easy, we don't sell slop. We pick ingredients with real backing, dose them at an effective dose, and leave the filler out, and results show this in 4K.
Most routines fail because they ask for ten steps nobody sticks to past week one. Ours are short on purpose. Just use it consistently, and it works.
What is the GHK-Cu copper peptide serum?
We call it Glow. It's our GHK-Cu copper peptide serum.
Supports the look of younger, tighter, firmer skin, and it's one of our most popular picks for anyone focused on skin quality and a more refined appearance over time. If you want one serum to start with, this is the one most people reach for. Also, heavily researched for its benefits.
How long until I see results?
Depends on what you're fixing. Hydration and texture show up fast, often in the first few weeks, sometimes days. The bigger stuff takes longer: anti-aging results from Glow build over months of consistent use, retinol needs weeks before texture and scarring look different, and supplements like Chill Pill build over 2 to 4 weeks.
We're not going to promise overnight, because that's how you end up with a drawer full of products you gave up on. Use it daily, and it works.
Are your products safe to use?
Yes. The skincare is fragrance-free, pH-balanced, and made for all skin types. The supplements are Non-GMO, hormone-free, antibiotic-free, and made in a cGMP certified facility.
One honest note: real actives deserve respect. Retinol is PM only, needs SPF the next morning, and you build up to nightly use. Vitamin C and retinol don't go on in the same application. Every product tells you exactly how to use it, so read the directions once and you're set.
How does the subscription work?
You pick a plan, we handle the rest. You can pause, skip a shipment, or cancel the plan at anytime from your account. Prefer no subscription? One-time purchase options are available.
Shipping is free over $75 and arrives in 3 to 7 business days with next-day processing.
What is your money-back guarantee?
If it doesn't work for you, return it, and you get a full refund. That includes products you've already opened and used within 30 days, no questions asked.
Message support@trymaxxing.com and we'll sort it out.
