Copper peptides are among the most buzzworthy beauty trends currently making waves.
Peptides are naturally occurring chains of amino acids that can aid in the production of collagen and elastin, two key connective tissues essential for smooth, firm skin.
While it’s normal to gradually lose collagen and elastin as you age, certain lifestyle habits — such as smoking and overexposure to the sun — can accelerate this loss.
In scientific terms, peptides are known as glycyl-L-histidyl-L-lysine (GHK), which readily binds with copper enzymes. The symbol for copper on the periodic table is Cu, so this combination is referred to as GHK-Cu.
Once collagen and elastin are lost, certain skin care products might help restore them. This is where peptides come into play.
Also known as polypeptides, they may specifically trigger increased collagen production in your skin, potentially addressing issues like:
- fine lines
- enlarged pores
- age spots
The connective tissue growth stimulated by copper peptides may also benefit your hair by reducing breakage and promoting overall growth.
However, it’s important to note that no beauty product can fully restore lost collagen and other connective tissues.
Read on to discover more about the potential benefits of copper peptides for your hair and skin, along with what the science has to say.
Hair Care Benefits of Copper Peptides
Copper peptides may promote overall hair health in several ways.
Enhanced Blood Circulation
According to a 2018 research review, copper peptides might help enhance blood flow in your skin. Copper itself is reported to support the tissues found in blood vessels.
As a result, copper peptides could potentially stimulate hair follicles by ensuring they receive sufficient oxygen and nutrients to encourage new hair growth.
Preservation of Hair Color
Copper is a micronutrient required for melanin production, the compound responsible for your hair’s color, as well as the color of your eyes and skin.
Additional Potential Benefits
If you’re experiencing hair loss, it might be due to a shortened hair growth cycle, which can be influenced by factors like hair follicles and hormones.
One potential benefit of copper peptides, according to a 2007 in vitro study, is the ability to prolong this growth cycle, leading to a longer time before hair falls out.
In addition to encouraging new hair growth, copper peptides might also thicken existing strands. It’s believed that enlarged hair follicles might contribute to this effect. However, more human studies are needed to confirm whether copper peptides can truly deliver these benefits.
Skin Care Benefits of Copper Peptides
The advantages of copper peptides in skin care have been well-documented.
Copper peptides can penetrate below the epidermis, or outer layer of skin, allowing them to generate elastin and collagen deep within the tissues.
Copper has been studied for its anti-aging effects on the skin. Here are some of the most promising benefits of copper peptides for skin care.
Diminished Wrinkles
Research on copper peptides has shown that they may help reduce the appearance of fine lines and wrinkles by boosting collagen production, according to a 2015 research review.
Over time, increased collagen may “plump up” the skin, reducing the visibility of wrinkles.
Firmer Skin
In addition to promoting collagen production, copper peptides are also believed to enhance elastin proteins, according to the same 2015 review. This may result in firmer, smoother skin.
Even Skin Tone
Copper peptides are unique among peptides for their potential ability to repair and even out skin tone.
It’s thought that copper peptides might help remove damaged connective tissues from the skin while simultaneously adding new ones. This could help reduce the appearance of:
- sunspots (also known as age spots)
- acne scars
- other causes of uneven skin tone
Antioxidant Properties
Copper peptides may also have antioxidant properties, which could help reduce inflammation and prevent further damage. GHK-Cu has also been reported to lower the risk of infections.
Using Copper Peptides for Skin and Hair Care
Copper peptides are commonly found in serums and facial moisturizers. It’s not recommended to use peptide-containing cleansers, as their effects will wash away after use.
Copper Peptides Serum
Copper peptides are most frequently found in serum form.
To use for hair growth, apply a few drops of serum to your scalp and gently massage it in with your fingertips. Do not rinse it out.
For skin concerns, incorporate your copper peptides serum into your skincare routine in the following order:
- Cleanser
- Toner
- Copper peptides serum
- Sunscreen (in the morning)
- Cream or moisturizing lotion (morning and evening)
Facial Moisturizer
Some facial moisturizers also contain copper peptides. For best results, choose a cream for dry skin or a lotion for normal to oily skin. Apply twice daily, morning and night, using gentle upward strokes.
Drawbacks and Limitations of Copper Peptides
While the benefits of copper peptides have been researched, their effects on skin have stronger scientific backing than their effects on hair care.
Overall, more human clinical trials are needed to confirm the efficacy of copper peptides.
Additionally, certain ingredients found in other skin care products may reduce the effectiveness of copper peptides. It’s advisable to avoid using copper peptides alongside the following ingredients:
- Retinol
- Vitamin C
- Alpha hydroxy acids (AHAs), such as glycolic acid (if you’re using an AHA-containing chemical peel, you can use copper peptides after your treatment)
Are There Any Risks or Side Effects?
Copper peptides in beauty products generally do not pose significant risks.
However, there may be some side effects associated with peptide-containing products. It’s important to test any new skin care product before using it widely on your face or scalp.
To conduct a patch test, apply a small amount of the product to the inside of your elbow and wait 24 hours. Discontinue use if any signs of an allergic reaction develop, such as:
- Redness
- Hives
- Itching
- Burns
Copper toxicity is another potential risk, but this is unlikely when using over-the-counter skin care products, as they typically contain a combination of ingredients alongside copper peptides.
Additional Insights on Copper Peptides
Copper peptides have garnered attention not just for their skin and hair benefits but also for their broader biological functions. These peptides are naturally occurring complexes that are critical in wound healing and tissue repair.
The tripeptide GHK-Cu has been studied for its role in modulating gene expression, affecting nearly 30% of the human genome, which underscores its potential in regenerative medicine.
Anti-Inflammatory Properties
Copper peptides are not just about boosting collagen and elastin. They are also recognized for their anti-inflammatory properties. Chronic inflammation is a significant contributor to the aging process and various skin conditions, including acne and rosacea. Copper peptides can help reduce inflammation, potentially making them beneficial for treating inflammatory skin conditions.
Wound Healing and Tissue Repair
In clinical settings, copper peptides have been used to enhance wound healing. This is particularly relevant for post-surgical recovery or treating scars, where the peptides accelerate tissue repair and reduce the appearance of scars.
This regenerative ability has made copper peptides a focus of research in developing new treatments for skin injuries and aging.
Enhanced Skin Barrier Function
The skin barrier is crucial for protecting against environmental stressors, allergens, and pathogens. Copper peptides can help strengthen the skin barrier, making the skin more resilient and less prone to damage.
This enhanced barrier function can also aid in maintaining moisture levels, which is essential for overall skin health and preventing dryness.
Application in Scalp Health and Hair Growth
Copper peptides have shown promise in improving scalp health, which is foundational for strong hair growth. They can potentially increase the size of hair follicles, leading to thicker hair strands.
Additionally, copper peptides may play a role in reducing dihydrotestosterone (DHT), a hormone linked to hair loss in both men and women. While research is ongoing, this could make copper peptides a valuable addition to treatments for androgenic alopecia (pattern baldness).
Integration with Other Skincare Regimens
For those interested in maximizing the benefits of copper peptides, it’s essential to consider how they fit into a broader skincare routine. Copper peptides should ideally be used with gentle, non-competing ingredients.
For instance, using products with hyaluronic acid or ceramides can complement copper peptides by providing additional hydration and barrier support. It’s also advisable to avoid using copper peptides with strong acids or retinoids at the same time, as these can reduce the peptides’ effectiveness.
Conclusion
Copper peptides represent a versatile and scientifically-backed ingredient in the realm of skin and hair care. Their ability to promote collagen production, enhance skin firmness, and potentially improve hair growth makes them a valuable addition to any beauty routine.
Beyond aesthetic benefits, copper peptides offer anti-inflammatory and wound-healing properties, showcasing their broader applications in skincare and regenerative medicine.
