What's inside

GHK-Cu · Copper Tripeptide-1

One of the most-studied peptides in skincare. Supports the look of firmness, elasticity and smoothness, and softens the appearance of fine lines.

Hyaluronic Acid · Sodium Hyaluronate

Holds up to 1,000× its weight in water — floods skin with lasting hydration for a plumper, dewier, bouncier look.

What to expect

Copper peptides work cumulatively — here's the typical journey.

DAY 1
Instant hydration. Skin drinks it in and looks instantly softer, dewier and plumper thanks to hyaluronic acid.
WEEK 2
Smoother surface. Skin feels smoother to the touch and looks more refreshed; that tight, dry feeling eases.
WEEK 4
Refined texture. Tone looks more even and texture more refined — makeup glides on smoother.
WEEK 8+
Firmer & radiant. The payoff: skin looks visibly firmer, bouncier and more radiant, and fine lines appear softened.

Frequently asked

Why is it blue?+
The blue comes naturally from the copper in GHK-Cu — it's a visual sign of the active peptide, not an added dye. It absorbs clear and won't stain your skin, pillow or clothes.
When will I see results?+
Hydration is immediate. Smoother-looking texture shows over the first few weeks, with firmer, more radiant-looking skin building over 8–12 weeks of daily use. Consistency is everything.
Are copper peptides better than retinol?+
They're different tools. Retinol can be powerful but irritating; copper peptides are prized for being gentle while supporting the look of firmness and smoothness. Many people use both — copper peptides on non-retinol nights.
Can I use it with vitamin C or retinol?+
Yes — just time them. Use vitamin C in the morning and your copper peptide serum at night. If you use retinol, alternate nights until your skin adjusts. It layers well with niacinamide, ceramides and moisturizer.
Is it safe for sensitive skin?+
Yes — it's fragrance-free, paraben-free and dermatologist-tested, and suitable for all skin types. As with any new active, patch test first and ease in 3–4x a week to start.
How long does one bottle last?+
Used morning and night, the generous 60ml bottle lasts around 2–3 months — so the 2-bottle bundle keeps you going for roughly half a year.
