Serum 48 GHK-Cu Copper Peptide Serum 1.2%

Three amino acids. One copper ion. Skin that behaves younger than it is.

GHK-Cu is a copper peptide your own skin produces — and produces steadily less of after 30. Serum 48 puts it back at 1.2%, above the 0.1–1% where most copper peptide serums stop. One dropper on clean skin, morning or night.

• Supports the skin's own collagen and elastin production for firmer-looking skin
• Helps soften the look of fine lines and refine uneven texture
• Supports the skin barrier and a calmer, more even-looking complexion
• Lightweight, fast-absorbing, fragrance-free — layers under everything

Why 1.2%

Copper peptides are signal molecules, not scrubs. They tell fibroblasts — the cells that build collagen types I and III, elastin and glycosaminoglycans — to get back to work. GHK-Cu has been studied since its discovery in human plasma in the early 1970s, and the mechanism is well documented: collagen and elastin signalling, antioxidant enzyme support, and a calming effect on the inflammatory cascade behind dull, tired-looking skin.

The catch is dose and stability. GHK-Cu is water-loving and charged, so it needs a properly built base to work through — and most commercial serums sit between 0.1% and 1%. Serum 48 is formulated at 1.2% in a pH-balanced, fragrance-free base, in tinted glass with a dropper, so the copper complex stays intact from first drop to last.

How to use

1. Cleanse and pat dry.
2. 4–6 drops across face and neck.
3. Wait 60 seconds, then follow with moisturiser — and SPF in the morning.
4. Once daily, morning or evening. Every day.

Layering note: keep pure vitamin C (L-ascorbic acid) and direct acids (AHA/BHA) to the opposite end of the day — low pH can destabilise the peptide. Niacinamide, hyaluronic acid, moisturisers and oils layer fine. If you use retinol, alternate evenings while your skin settles in.

What to expect

• Weeks 1–2: skin feels more hydrated and reads smoother to the touch.
• Weeks 4–6: texture and tone start to even out.
• Weeks 8–12: the firmness and fine-line changes people actually notice.

Peptides signal rather than strip, so there's no purge and no downtime — but there's also no shortcut. Consistency beats intensity.

Why most people order 3 bottles

Visible change from a peptide takes about three months of daily use — that's three bottles. Buying one means reordering twice at full price. The Buy 2, Get 1 Free bundle covers the full 90 days for $124.95 instead of $209.85, and it's the only option that matches the 90-day guarantee.

Size: 30 ml / 1 fl oz — approximately one month of daily use per bottle.

Skin types: all, including sensitive. Fragrance-free. Patch test on the inner forearm for 24 hours first; copper allergy is uncommon but real.
