What Is GHK-Cu Copper Peptide?

GHK-Cu stands for Glycyl-L-Histidyl-L-Lysine Copper.

It is a naturally occurring copper-binding tripeptide that has become one of the most recognized ingredients in advanced peptide skincare.

Copper peptides such as GHK-Cu are widely used in cosmetic formulations designed to support the appearance of smoother, firmer and healthier-looking skin.

Our concentrated 10% GHK-Cu serum pairs this advanced peptide with hyaluronic acid and glycerin to provide targeted peptide skincare plus lightweight hydration.

What Does GHK-Cu Do for Skin?

As skin ages, it can gradually begin to look less firm, less smooth, uneven and less vibrant.

GHK-Cu is an excellent addition to an advanced anti-aging skincare routine when your goal goes beyond basic hydration.

Fine Lines & Wrinkles

Helps support the appearance of smoother, more refined-looking skin and visibly soften signs of aging.

Loss of Firmness

Ideal for mature-looking skin that has begun to appear less firm or resilient.

Uneven Skin Texture

Supports a smoother, healthier and more refined-looking complexion.

Dull, Tired-Looking Skin

Complements a skincare routine focused on restoring a fresher, more vibrant appearance.

Visible Signs of Aging

An advanced copper peptide treatment for anyone building a serious anti-aging or skin longevity skincare routine.

Why 10% GHK-Cu?

Concentration matters when choosing a copper peptide serum.

I’M FABULOUS GHK-Cu Serum features a 10% concentration for customers looking for an intensive copper peptide treatment.

Because this is a concentrated formula, more is not necessarily better.

A few drops are all you need.

If you are new to concentrated copper peptide skincare, introduce the serum gradually and adjust frequency according to your individual skin tolerance.

The Formula

Advanced skincare does not need an unnecessarily complicated ingredient list.

Our GHK-Cu Copper Peptide Serum contains just five carefully selected ingredients.

GHK-Cu Copper Peptide
The hero peptide in this concentrated formula, used in advanced skincare designed to support smoother, firmer and healthier-looking skin.

Hyaluronic Acid
Helps attract moisture for a plumper, softer and more hydrated appearance.

Glycerin
Helps maintain moisture and supports soft, supple-looking skin.

The result is a lightweight, highly focused copper peptide serum that layers easily into an advanced skincare routine.

How to Use GHK-Cu Copper Peptide Serum

Because this is a 10% concentrated GHK-Cu serum, we recommend introducing it gradually.

Apply 2–3 drops to clean, dry skin 2–3 times per week when beginning your routine.

Gently smooth or press the serum onto the face and neck, concentrating on areas showing visible signs of aging.

Allow the serum to absorb before applying your moisturizer.

As your skin becomes accustomed to the formula, adjust frequency according to your individual skin tolerance.

During the daytime, always finish your skincare routine with sunscreen.

What Should You Not Mix With Copper Peptides?

When using a concentrated copper peptide serum, a simple routine can be beneficial.

If your skincare routine includes strong exfoliating acids, low-pH L-ascorbic acid vitamin C or other potentially irritating active treatments, consider using them at a different time of day or on alternate days rather than layering several powerful actives together.

For example:

Morning: Vitamin C routine

Evening: GHK-Cu Copper Peptide routine

You can also alternate active-treatment days according to your skin's individual tolerance.
