Supports the skin processes behind a firmer, bouncier feel over eight weeks.
A glycerin–hyaluronate base comforts a stressed moisture barrier from day one.
Made for faces that lost volume fast — loose-skin support after weight loss.
Four drops, twice a day. No injections, no mystery vials, no guesswork.
GHK-Cu is not a trend molecule someone found on a forum. It's a copper tripeptide your own plasma has carried since the day you were born — levels simply fall with age.
Three amino acids — glycine, histidine, lysine — bind one copper ion. Applied to skin, the complex behaves like a memo to your cells: time to make more of the good stuff.
It supports skin's own collagen-and-elastin economy — the scaffolding behind visible firmness and elasticity. Slow, structural work, not an instant-blur filter.
A humectant base of glycerin and hyaluronate buffers the copper complex and pulls water in, so the barrier feels calm while the peptide does its quiet work.
Cosmetic product. Glow Drops supports the look and feel of skin — it doesn't treat, cure or prevent anything.

Every Peppies subscription includes Peptide Passport tracking. This is the shape of the average self-logged skin score among Glow Drops members — not a clinical trial, and not a promise.
The base works before the peptide story begins: members typically log a plumper, better-hydrated feel and less tightness after cleansing.
Smoother texture is the usual entry: makeup sits better, rough patches show up less often in the logs.
The GHK-Cu chapter. Members log a firmer, denser feel — post-GLP members log it most, on cheeks and jawline.
Aggregated from member Passport logs. Self-reported, not a clinical study. Individual results vary — talk to your doctor about anything medical.

Post-Weight-Loss Skin room →I bought it for the firmness story and stayed for the ritual. Week five and my skin feels properly hydrated for the first time since my twenties — and scanning the cap to pull up my own batch certificate is stupidly satisfying.
Lost a lot of weight on my GLP-1 programme and my face paid for it. Eight weeks of Glow Drops and my Passport skin score climbed from 66 to 74 — cheeks feel denser, less crepey. Not magic. Just consistent.
Took my sensitive skin two weeks to settle in — slight tightness early, then nothing. One star off because I want a bigger bottle. The nameless bottle lives in my gym bag and nobody asks questions, which is exactly the point.
I read INCI lists for sport. This one is short, fragrance-free, and the copper peptide sits second on the actives — not a fairy-dust footnote. Texture is water-silk and it behaves under SPF.

No fairy-dust footnotes. This is the actives map for LOT 0424 — function, where it lands on the list, and the level we formulate to. The full INCI is above; this is the part that earns its place.
| Ingredient (INCI) | What it does | List position | Level |
|---|---|---|---|
| Copper Tripeptide-1 GHK-Cu |
The headline. Signals skin's own firmness-and-barrier economy. | 4th — first active | 0.05% |
| Sodium Hyaluronate | Low-weight humectant — pulls and holds water in the upper layers. | 5th | 0.30% |
| Panthenol (Pro-Vit B5) | Soothes and supports a calm, comfortable barrier feel. | 6th | 1.00% |
| Allantoin | Conditioning agent for smoother-feeling, less-reactive skin. | 8th | 0.20% |
| Glycerin + Betaine | The humectant base — the comfort layer the peptide rides on. | 2nd + 7th | Base |

We grade our own evidence in plain sight, and we draw the line between what Glow Drops is and what it will never be. Read both before you buy.
Decades of cosmetic-ingredient research and a long human-use history back topical copper peptides for the look and feel of firmness. Marked down from A because most studies are small and industry-adjacent. Honest, not hyped.
Read the graded evidence →The same grading runs across the Compendium, so a B here means the same as a B anywhere.
This honesty is the product. If a claim isn't on this page, we're not making it.
