Glow Recipe Pomegranate Copper Peptides Face Serum

Copper peptides plus a jellyfish-derived peptide with essentially no independent evidence. The immediate firming you feel is a film, and the brand says so.
At a Glance
Mixed

The copper peptide (GHK-Cu) is genuinely included and well placed. Copper peptides have more independent literature than most cosmetic peptides, though much of it concerns wound healing rather than anti-aging on intact skin.

The headline marine peptide, Sr-Hydrozoan Polypeptide-1, is essentially unproven — a new proprietary ingredient with no independent published human data we could find. The immediate tightening you feel is not the peptides at all; it is pullulan, a film-former that tightens as it dries and washes off at night. Glow Recipe discloses this honestly, which is worth acknowledging.

The wider topical peptide evidence is thin, and pomegranate antioxidants have limited data too. Copper and vitamin C also cancel each other out, so keep them at separate times of day.

How it works

The copper peptide is well placed — position seven, a genuine inclusion.

The immediate tightening is honestly disclosed as a film effect from pullulan, rather than being attributed to the peptides. That is a small piece of integrity worth acknowledging in a category where most brands would not bother.

Pomegranate antioxidants are a reasonable complementary addition, though the evidence for topical pomegranate is thin.

The texture is genuinely pleasant and well tolerated.

Peptides are the most oversold category in skincare, and this is the honest picture.

A 2026 systematic review in Frontiers in Medicine pooled 19 randomized trials of peptides. Only two of them tested topical peptides — the rest tested oral collagen supplements. And the wrinkle benefit the review found was driven almost entirely by the oral studies, not the topical ones. Elasticity showed no meaningful effect at all.

There is also a physical problem. Peptides are large molecules, and the skin barrier is very good at keeping large molecules out. Independent reviews of the penetration data are blunt about it: most topical peptides concentrate in the outermost dead layer of skin and drop off sharply below that — nowhere near the depth where collagen is actually made.

And most of the foundational research comes from the companies that sell the peptides — Sederma, Lipotec — rather than from independent labs.

None of this means peptides do nothing. They are gentle, they are well tolerated, and there is a real argument for them in skin that cannot handle retinoids. But be clear on the comparison: retinoids have decades of large, independent, randomized evidence for wrinkles and photoaging. Peptides do not. Gentler, yes. Equally proven, no — not close.

Everyday habits

How to use it
  • When: morning or night.How much: a few drops on clean skin. Steps: apply before moisturizer and let the gel absorb. Vitamin C: copper degrades L-ascorbic acid, so use this and any vitamin C at different times. If it pills: use less and pause between layers.
Who should be careful+

Sr-Hydrozoan Polypeptide-1 is essentially unproven. It is a new, proprietary marine peptide, and we could find no independent published human data on it at all — the evidence is confined to the supplier's own materials. It is a headline ingredient with nothing behind it that we can verify.

The "firming" you feel is pullulan, a film-former. It tightens as it dries and washes off at night. Real sensation, no lasting effect.

Copper peptide evidence is largely from wound healing, not intact-skin anti-aging.

$45 for 30 ml, with no disclosed peptide concentrations.

Do not layer it with vitamin C — copper degrades L-ascorbic acid.

Questions people ask+
Is the firming real?The immediate tightening is a film from pullulan, not a lasting effect.
Is the marine peptide proven?No. It has essentially no independent human evidence.
Can I use it with vitamin C?Not at the same time. Copper and vitamin C undo each other.
Is it fragrance-free?No. It contains added fragrance.
Is it gentle?Generally yes; the texture is pleasant and well tolerated.
