A high-strength daily serum built around 2% Copper Peptide (GHK-Cu) for firmer, smoother and more renewed-looking skin.

2% Copper Peptide (GHK-Cu) - our hero active, at a high published strength
Supports firmer, smoother, more resilient-looking skin
No parabens · no mineral oil · no synthetic fragrance

Best for: those wanting firmer, smoother, more radiant-looking skin from a gentle daily peptide serum.

Key Benefits

Firms & smooths - supports the appearance of firmness, elasticity and a smoother texture
Softens fine lines - helps reduce the look of fine lines and dullness
Antioxidant defence - helps protect against the daily environmental stress that dulls skin
Deep hydration - multi-weight hyaluronic acid for a plump, hydrated feel

What to expect: smoother, more hydrated skin within days; firmer, more even-looking results build over 8–12 weeks of consistent use.

How to Use

Use morning and evening. After cleansing, press 3-4 drops onto slightly damp skin across the face and neck - pat gently, don't rub. Let it absorb for about a minute, then follow with your moisturiser. In the morning, always finish with SPF.

Tip: this serum layers well with niacinamide and stable Vitamin C. If you separately use pure L-ascorbic Vitamin C, strong acids (AHA/BHA) or high-strength retinol, apply those at a different time of day.

Complete the routine: seal it in with the Copper Peptide (GHK-Cu) Day Gel-Cream in the morning, or the Copper Peptide (GHK-Cu) Night Cream in the evening.

No pilling, no greasy layer

Love this. I use it in the evening before my moisturiser and it doesn't pill or leave that greasy layer some serums do. After around a month I noticed my skin texture looked much smoother in daylight.

Smoother and more resilient

I was curious about copper peptides after reading so much about them and decided to give this serum a try. The texture is beautiful and feels very calming on the skin. After about three weeks my skin feels smoother and definitely more resilient and firmer.

Already a lifetime fan

I'm 47 and mainly bought this for the skin repair qualities. I had very irritable skin and at times it was painful and really didn't help my confidence. But after five weeks my skin has been transformed. It's beautifully healthy now, it definitely feels softer and my skin has more bounce to it. I'm already a lifetime fan.

A much healthier glow

This has quickly become one of my favourite products in my evening routine. My skin was looking a bit dull and tired, and after several weeks it has a much healthier glow. I also feel like the fine lines around my eyes are less noticeable.

A surprisingly big difference

I have quite dry skin and this has made a surprisingly big difference. My face feels much more comfortable and hydrated throughout the day, without feeling oily. Even my make-up seems to sit better on my skin now.

I can't go a day without it

Straight away I noticed results with the copper peptide treatment. After the first week my skin looked clearer and more balanced. People ask me now how I got my skin so hydrated and bright, with less redness. I don't think I can go a day without it.

It impressed me

I wasn't expecting much because I've tried a lot of expensive serums before, but this one has impressed me. My skin feels smoother, looks brighter and the overall tone seems more even and fuller. I'll definitely keep using it.

The colour surprised me

The blue colour surprised me at first, but I actually love the look and feel of this serum. It feels very lightweight and a little goes a long way. After a few weeks my skin seems firmer and the texture around my cheeks looks noticeably better.

It feels much more premium

Really nice serum, and it feels much more premium than most products I've tried. It sinks into the skin almost immediately and works well under my moisturiser. After the first few days my complexion already looked more even and rested, and after a few weeks of consistent use the difference is noticeable. I regularly get compliments about my skin.
