How To Use

How To Get The Most From Your Serum

Start slow and let your skin acclimate... especially if you're new to active peptide formulas. Less is more with GHK-Cu.

✓ DO:

  • Start with every other night for the first 1–2 weeks to allow your skin to acclimate
  • Apply 2–3 drops to clean dry skin. A little goes a long way
  • Gently press into skin using fingertips rather than rubbing
  • Follow with your moisturizer to lock in the peptides
  • Use consistently. GHK-Cu works cumulatively, results build over weeks not days
  • Apply SPF in the morning. Active ingredients make skin more sun sensitive

✗ DO NOT:

  • Over-apply: more product does not mean faster results and can cause irritation
  • Use on broken or compromised skin
  • Mix with high concentration vitamin C in the same application. Can reduce peptide efficacy
  • Expect overnight results: give it a full 4–6 weeks for visible change
  • Skip moisturizer after application
Who Is This For?

Is This Serum Right For You?

GHK-Cu is a clinically studied peptide, not a trendy ingredient. It's formulated for people serious about results.

✓ This is for you if:

  • You're noticing the first signs of aging: fine lines, loss of firmness, or skin that's lost its bounce
  • You want visibly luminous skin that reflects how you actually take care of yourself
  • You've tried basic moisturizers and serums and want something with more advanced ingredients
  • You're ingredient-conscious and want real science behind what you put on your skin
  • You're committed to a consistent routine; you understand real results take weeks not days
  • You want a clinical formula without a clinical price tag

✗ This probably isn't for you if:

  • You're looking for an instant overnight transformation
  • You want a light everyday moisturizer; this is an active serum
  • If you have a skin condition or sensitivity, consult your dermatologist before use
  • You're not ready to be consistent; this formula rewards commitment

FAQs

What is GHK-Cu and does it actually work?

What is GHK-Cu and does it actually work?

GHK-Cu (copper peptide) is a naturally occurring compound found in human plasma, saliva, and urine that was first identified in the 1970s. It consists of a small protein fragment — glycine, histidine, and lysine — bound to a copper ion, which gives it its unique properties.

As we age, GHK-Cu levels in the body decline significantly. At age 20, plasma levels sit around 200 ng/mL — by age 60 that drops to roughly 80 ng/mL, a change researchers have studied in connection with visible signs of aging.

What the research shows:

GHK-Cu is one of the more extensively studied peptides in skincare, with decades of peer-reviewed research behind it — relatively rare in the peptide space. Published studies have explored its association with visibly firmer-looking skin, a more even complexion, and the appearance of fine lines and uneven tone.

Does it actually work on skin?

The honest answer is yes, with realistic expectations. GHK-Cu won't produce overnight results or replicate the outcome of a clinical procedure. With consistent use, most people report noticeable improvements in the appearance of skin texture, firmness, and overall radiance within 8 to 12 weeks.

It works best as part of a consistent routine rather than a quick fix — which is true of any advanced skincare ingredient.
How long until I see results?

Most people begin noticing initial changes in skin texture and hydration within 2 to 4 weeks of consistent use. These early changes are often subtle — skin feeling smoother, looking more even, or having a healthier baseline glow.

The more significant results — visibly improved firmness, a softer appearance of fine lines, and overall skin quality — typically become noticeable between 8 and 12 weeks. This is because GHK-Cu is one of the most extensively studied peptides in skincare, and visible improvements in appearance take time to develop. Skin cell turnover alone takes roughly 28 days, which is why no topical ingredient — regardless of what it claims — produces dramatic results overnight.

What affects your timeline:

  • Consistency — daily use produces meaningfully better results than occasional use. Skipping days slows the cumulative effect significantly
  • Your starting point — people with more visible signs of aging often notice changes sooner because there is more visible improvement to be seen
  • Age — younger skin tends to respond faster due to naturally higher baseline skin resilience
  • Your full routine — GHK-Cu works best when not paired with harsh products that disrupt the appearance of a healthy skin barrier

We recommend committing to at least 60 days before drawing conclusions. Most customers who give it that window report results they can see and feel. Most who are disappointed stopped too early.
How much should I apply and how often?

Amount: 3 to 5 drops is all you need. GHK-Cu is a concentrated active — more product does not mean faster or better results.

Frequency: Once daily to start, preferably in the evening. After your skin has acclimated, you can move to twice daily if desired.

Acclimation Period

If you are new to peptide serums or actives in general, we recommend starting with every other day for the first 1 to 2 weeks. Some people experience mild sensitivity when introducing a new active — starting slow lets your skin adjust without overwhelming it.

Signs your skin is acclimating normally: mild tingling, temporary redness, or skin feeling slightly different in the first few days. These typically resolve on their own.

If you experience persistent irritation, reduce frequency and give your skin more time to adjust. If irritation continues, discontinue use and consult a dermatologist.

Suggested Routine Order:

  1. Cleanse
  2. Tone (if used)
  3. Apply serum to clean, dry skin
  4. Wait 60 seconds to absorb
  5. Moisturizer
  6. SPF (morning only)

Pro tip: Avoid using alongside strong exfoliating acids or retinol in the same application until your skin has fully acclimated. Alternating evenings works well for most people.
Where are your products manufactured?

Made in Texas, USA

Every bottle is formulated and manufactured right here in Texas. No overseas outsourcing, no mystery supply chains — just a clean, controlled process from start to finish.

We chose to keep production domestic because it means tighter quality control, faster turnaround, and full visibility into every step of how your serum is made. When you know exactly where something comes from, you can stand behind it completely.

That's the standard we hold ourselves to.
Will this work for my skin type?

GHK-Cu Serum is formulated to work across all major skin types. Here's what to expect based on yours:

Dry Skin
The Sodium Hyaluronate in this formula draws moisture deep into the skin, making it a strong fit for dry skin. Most people with dry skin notice improved hydration and a plumper, more comfortable appearance within the first few weeks.

Oily & Combination Skin
This serum is lightweight and absorbs quickly without leaving a greasy residue. Niacinamide helps visibly minimize the appearance of pores and shine, making it well suited for oily and combination skin types.

Sensitive Skin
Centella Asiatica and Fermented Reishi + Shiitake are both included specifically for their skin-calming properties. That said, if your skin is reactive we recommend starting with every other day and patch testing first. If you have a diagnosed skin condition, consult your dermatologist before use.

Mature Skin
This formula was designed with visible signs of aging in mind. GHK-Cu and Acetyl Hexapeptide-8 are both extensively studied in the context of mature skin appearance, making this a particularly strong fit for skin showing fine lines, loss of firmness, or uneven texture.

Normal Skin
You're in good shape. This formula layers well into any existing routine and works best as a consistent daily step rather than an occasional treatment.

If you're ever unsure, patch testing on a small area for a few days before full use is always a good approach.
