How to Use GHK-Cu Cream: Timing, Amount and What to Expect

Follow the directions on your prescription label, which your licensed provider sets for your skin. In general, copper peptide creams are applied to clean, dry skin, often once a day, before moisturizer, and you wear a broad-spectrum sunscreen every morning. Small human studies of topical GHK-Cu usually measured changes over about 8 to 12 weeks, results vary, and no outcome is promised.

Before your first use

Patch test. Apply a small amount behind the ear or on the inner forearm for a few days. Copper allergy is uncommon but possible, and creams contain other ingredients that can irritate sensitive skin.

Check your routine. If you use a retinoid, strong acids or a vitamin C serum, plan to separate them from your copper peptide step. Our article on layering GHK-Cu explains common approaches.

Step by step

1. Wash with a gentle cleanser and pat skin dry.
2. Take a small amount, about a pea-sized portion for the face unless your label says otherwise.
3. Warm it between your fingertips and press it gently over the face, avoiding the eyes and lips. Many people include the neck.
4. Let it absorb for a minute or two.
5. Apply your moisturizer.
6. In the morning, finish with a broad-spectrum sunscreen.

Avoid broken, irritated or freshly treated skin, such as right after a peel or laser treatment, unless your provider tells you otherwise.

Morning or night?

Either can work. Many people choose evening so that a morning vitamin C serum and sunscreen stay simple. If you use a retinoid at night, you might apply copper peptide on alternate nights or in the morning. Your label and provider have the final word.

What to expect over time

Pickart and Margolina's 2018 review describes small human studies of topical GHK-Cu that reported improvements in skin firmness, fine lines and density, typically measured over about 8 to 12 weeks. Many of these studies were small or industry funded, so think of copper peptide as a supporting step rather than a sure thing. Daily sunscreen and, where tolerated, a retinoid have stronger evidence, as summarized in Mukherjee and colleagues' 2006 review of retinoids.

Track how your skin feels and looks with a monthly photo in the same light. It is easier to judge gradual change that way.

Storage and handling

Keep the jar closed, away from heat and direct sunlight, and use clean fingers or a spatula. Do not share it. If the color or smell changes noticeably, or the jar arrives damaged, contact support before using it.

About your prescription

Golden Glow's GHK-Cu cream comes in 2% and 4% strengths and is compounded by a licensed US pharmacy on a provider's prescription. The FDA explains that compounded drugs are not FDA-approved and that it does not verify their safety, effectiveness or quality before they are dispensed.

Frequently asked questions

How much GHK-Cu cream should I use?

A thin layer, often about a pea-sized amount for the face, unless your label says otherwise. Using more does not speed up results and may raise the chance of irritation.

Can I use it around my eyes?

Avoid the eye area itself. Some products are suitable near the orbital bone, but ask your provider before using it close to the eyes.

Does GHK-Cu cause purging?

GHK-Cu is not known to cause purging the way retinoids or acids can, but any new product can cause irritation or breakouts in some people.

Can I use it while pregnant or breastfeeding?

There are not enough studies to know. Tell your licensed provider if you are pregnant, trying to conceive or nursing.
