How To Use

For transformative results, targeting redness and sensitivity, we recommend using the GHK-Cu Repairing Serum consistently every day, morning and night. As a skin reset, the GHK-Cu Repairing Serum can be used for 2 weeks to restore skin after abrasive beauty treatments or as part of a regular skin cycling regime. 

Once activating one serum, for best results use within 2 – 4 weeks as the ingredients are at their most active and effective. The serum is still fresh up to 6 months after opening (with the activeness slowly depleting over time).

Application Guide

Pre-application

Before applying the GHK-Cu Repairing Serum, cleanse your skin and allow it to dry.

Application

To activate your serum, firmly push the top down against a hard surface to release the powder into the solution. Shake thoroughly for up to 30 seconds – check the lid to ensure all the powder has been mixed into the solution. Remove the lid (and recycle it) and replace with the dropper lid. Shake well before every use. Squeeze the dropper to draw up the serum to start applying it to your face. Ensure skin is clean, then lightly disperse the product around the parameter of the face. Follow this same process on other areas around the face, neck, and décolletage, or area of concern.

Post-application

Once dried, moisturise and apply sunscreen (in the morning) as per your usual skincare routine.

Frequently Asked Questions

We know skincare can be tricky, especially when it comes to biotech. Here are some quick answers to common questions. Need more help? Our customer service team is here for you!

What is the ingredient GHK-Cu?

GHK-Cu, also known as Copper Tripeptide-1, is a natural growth factor made up of three amino acids and one copper ion. This unique combination enhances the overall health and appearance of the skin by stimulating collagen production, improving skin elasticity, and reducing fine lines and wrinkles. GHK-Cu also helps to support skin repair and provides anti-inflammatory benefits, making it ideal for sensitive or damaged skin. Research has shown that copper peptides, like GHK-Cu, are highly effective in wound healing and tissue regeneration.

What are the benefits of GHK-Cu?

Repairs the skin barrier: GHK-Cu stimulates collagen production, promoting the synthesis of new skin cells and accelerating the repair of damaged skin. Reduces the appearance of wrinkles: By boosting collagen and elastin production, GHK-Cu helps reduce the formation of fine lines and wrinkles, giving the skin a smoother, more youthful appearance. Anti-inflammatory: GHK-Cu’s potent anti-inflammatory properties make it ideal for soothing sensitive or inflamed skin, helping to reduce redness, calm irritation, and restore the skin’s barrier function.

Why is the GHK-Cu serum stored in two-part packaging?

The GHK-Cu Repairing Serum is stored in innovative two-part packaging to maintain the freshness and potency of the active ingredients. GHK-Cu is sensitive to exposure to light and oxygen, and can lose its effectiveness over time. To ensure you receive the purest and most active form, the serum is stored as a powder in the lid and the copper solution in the base. The serum is activated only when the powder and solution are combined, ensuring that you receive the most potent, freshly activated product each time you use it.

Can GHK-Cu Repairing Serum help with skin redness or irritation from acne or other conditions?

Yes, the GHK-Cu Repairing Serum is specifically formulated to reduce redness and irritation caused by acne, rosacea, or other skin conditions. The copper peptides in the serum work to calm inflammation, repair the skin barrier, and promote healing, which helps to reduce flare-ups and restore skin to its natural, healthy state. It’s an excellent option for those with sensitive or reactive skin prone to redness and irritation.

How does our smaller packaging size benefit the efficacy of the product?

Our smaller 10ml bottle size ensures that the serum remains fresh and potent throughout its use. When a large bottle is opened repeatedly, exposure to air and light can degrade the active ingredients, reducing their effectiveness. By using smaller bottles, you open and use one at a time, keeping the remaining serum sealed and protected from external factors. This preserves the serum’s potency for longer, ensuring you always receive maximum benefit from each application.

How do I choose the right serum for my skin?

When choosing a serum, focus on your specific skin concerns rather than skin type. Look for products that address your unique needs—such as hydration with hyaluronic acid, brightening with vitamin C, or anti-ageing with retinol. Read product descriptions carefully to find the serum that best aligns with your skin goals. If you're unsure, consider consulting a skincare professional to help guide your choice.

Can I use multiple serums together, and if so, what is the recommended order of application?

Yes, you can use multiple serums to address various skin concerns. To maximise the effectiveness of each serum, apply them in order of consistency, starting with the thinnest and allowing each one to fully absorb before moving on to the next. If you’re using active ingredients such as acids or retinol, we recommend incorporating them into a skin cycling routine, applying them on alternate nights to avoid irritation. If you're unsure about which serums work well together, it’s always a good idea to consult a skincare professional for personalised advice.

    Bought twice from Myer and hope they are never out of stock ever.

    I did a search for GHK Cu and was given a link to Myer and found these products. I have never been able to get the redness out of my nose. I have never had a serum I had to activate so that was something new. I applied this serum to my face as well my extensive skin care routine left the mirror for about half an hour walked past the mirror again and took a double take the redness was completely gone... I can't stop telling my fellow red girls to get this product it is my holy grail.

    Impressive serum

    This GHK-Cu repairing serum has quickly become one of my skincare staples. I loved that it came as a mix-it-yourself formula—it was simple to put together, and I felt reassured knowing the ingredients were freshly activated for maximum potency.

    The texture caught me off guard at first—it’s quite fluid—but that turned out to be a good thing. It glides over the skin effortlessly and sinks in fast without leaving any sticky or greasy feeling behind. After using it consistently, I noticed a big improvement: my skin felt calmer, more moisturized, and those stubborn dry areas became much softer and smoother.

    Also, the packaging is beautiful. The bottles feel sleek and luxurious, which added a nice touch to the routine. This serum definitely earned a permanent spot on my skincare shelf.

    Just divine! Super hydrating and soothing!

    I really liked this serum, the dispenser is super cute, feels like great quality packaging. The serum is so lovely, feels great applying it to your skin, distributes well and is easily absorbed into your skin. It smells nice and leaves your skin feeling really hydrated, smooth and silky, I noticed visible results in my skin, it looked less dull and much more hydrated and plump after using.

    I received this product as a gift for my honest review.
