Scroll through skincare content for five minutes and you will hear about peptides, copper peptides and PDRN. Some of it is hype, and some of it is genuinely useful. ABK SKIN summed it up on Instagram: "Peptides have been changing the skin WAY before they started trending."
This guide explains the ingredients in plain English, where they show up at ABK SKIN, and how to get the most from them without wasting money.
What peptides are
Peptides are short chains of amino acids, the building blocks of proteins such as collagen and elastin. In skincare, different peptides are used to send different messages to the skin. Some are chosen to support firmness, some to help with the look of fine lines, and some to calm or hydrate.
Peptides are generally well tolerated, which is one reason they are popular. They are also slow and steady. Expect gradual change with consistent use rather than an overnight difference.
GHK-Cu: the copper peptide
GHK-Cu is a peptide bound to copper. In skincare it is chosen to support collagen and elastin, with the aim of improving firmness, elasticity and the visible signs of aging. At ABK SKIN, it is one of the key actives in the Microneedling + GHK-Cu + PDRN treatment.
One important note: ABK SKIN uses GHK-Cu as part of a professional microneedling treatment, not as an injectable. Injectable GHK-Cu has become a trend of its own, and it is outside what an aesthetician offers. Never inject anything bought online, and talk to a licensed medical provider about anything injectable.
PDRN
PDRN (polydeoxyribonucleotide) is made from DNA fragments, commonly salmon-derived, which is why the treatment it appears in is nicknamed the salmon sperm facial. It is used to help support the skin's natural repair and renewal processes, with the aim of improving skin quality, texture and radiance.
The supporting cast
The NEXGen PDRN+ formula used at ABK SKIN also includes:
- Spermidine, included to support healthy skin renewal and barrier function.
- Amino acids such as arginine, included to help skin recover.
- Hyaluronic acid, which holds water to deliver hydration and help skin look plumper and smoother.
Topical products versus in-studio treatments
There is a difference between a peptide cream you apply at home and a peptide serum delivered during a professional treatment.
At home
Peptide products sit on the surface and work gradually. They are a good everyday support for firmness and hydration. A few from the ABK SKIN shop:
- Intellishade Original (Revision Skincare). A tinted moisturizer with SPF 45 that includes a blend of three peptides alongside vitamin C. Peptides and sunscreen in one step.
- Renewing HA Serum (Hydrinity). A hydrating serum built on Hydrinity's patented hyaluronic acid.
- Nectifirm Advanced. A neck and décolleté treatment with eight peptides. The neck is often forgotten, and it shows.
In the studio
During microneedling, a professional serum can be delivered through tiny channels in the skin. That is the idea behind ABK SKIN's Enhanced Microneedling options. HydraFacial boosters work on a similar principle at the surface: the Platinum HydraFacial finishes with a booster chosen for what your skin needs that day, whether that is dullness, dehydration, fine lines, congestion or uneven tone.
How to use peptides well
- Be consistent. Peptides reward daily use over months.
- Do not chase every trend. One well-chosen peptide product beats five overlapping ones.
- Protect your results. Sunscreen does more for the look of fine lines than almost anything else.
- Pair with professional care. A home routine and periodic treatments support each other.
- Ask before layering. Some actives do not play well together, and your aesthetician can simplify your routine.

The takeaway
Peptides, copper peptides and PDRN are useful tools, not magic. Used consistently at home and paired with the right professional treatment, they can help your skin look healthier, firmer and better hydrated over time. If you want help choosing, bring your current products to a consultation.
Frequently asked questions
Can I use peptides with retinol?
Peptides are generally easy to pair with other ingredients, including retinoids. If your skin is sensitive, introduce one new product at a time.
Are peptides good for sensitive skin?
Peptides are generally well tolerated, but always patch test new products and ask if you have a history of reactions.
How long until I see results?
Peptides work gradually. Give a product several weeks of consistent use.
Is GHK-Cu the same as PDRN?
No. GHK-Cu is a copper peptide. PDRN is made from DNA fragments. The NEXGen PDRN+ serum used at ABK SKIN contains both.
Do I need a professional treatment to benefit?
No. Home products help on their own, and professional treatments can add to them.
