Frequently Asked Questions

Does topical GHK-Cu actually work?

GHK-Cu is one of the most studied peptides in skincare — over 70 published studies covering collagen production, skin elasticity, wound repair, and cellular regeneration. It's not a new ingredient and it's not a trend. It was first identified in 1973 and has decades of research behind it.

The reason most people don't see results from copper peptide products isn't the ingredient — it's the dose. The majority of brands formulate at 0.5–1% to cut costs. At that concentration, you're unlikely to notice much. Our formula uses 2% — the maximum effective topical concentration — which is why our customers see results that other serums haven't delivered.

How long until I see a difference?

Here's an honest timeline based on what our customers consistently report:

Week 1: Less morning puffiness. Skin looks slightly cleaner and more refreshed. The hyaluronic complex is working immediately — you'll notice the hydration before the peptide effects fully kick in.

Weeks 3–4: Smoother texture, more even tone. This is when people start asking what you've changed. You'll notice it in photos and in normal lighting.

Weeks 8–12: Firmer, more defined-looking skin. This is the compound result of consistent daily use — collagen signaling takes time to show up structurally, but when it does, the difference is noticeable.

Individual results vary. But if you stop after two weeks because you haven't seen a dramatic change yet, you've quit before the best part.

Can I use it with retinol or vitamin C?

Yes — but timing matters.

With retinol: Don't apply them at the same time. GHK-Cu and retinol can counteract each other when layered simultaneously. The protocol that works: GHK-Cu in the morning, retinol at night. You get the benefits of both without interference.

With vitamin C: Apply vitamin C first, let it fully absorb, then apply GHK-Cu on top. Both are morning-friendly actives and they don't conflict when applied this way.

With SPF and moisturizer: No issues. Apply GHK-Cu first, let it absorb, then layer your moisturizer and SPF over it as normal.

If you're already using retinol and want to add this, the 6-month supply is the right call — you're building a long-term stack, not testing a single product.

Will it break me out or clog pores?

No. The formula is non-comedogenic, oil-free, and fragrance-free. It won't clog pores and it doesn't contain any of the common irritants — no parabens, no sulfates, no synthetic dyes, no artificial fragrance.

It's a lightweight water-based serum. It absorbs fully within about 60 seconds and leaves no residue. The vast majority of customers — including those with sensitive or acne-prone skin — tolerate it without any issues.

If you're extremely sensitive, we recommend a 24-hour patch test on your inner arm before full application. But breakouts from this formula are not something we hear about.

Why do you recommend 3 or 6 bottles instead of one?

Peptide results compound with consistent use. One bottle is roughly a 2-month supply; the 3- and 6-bottle protocols cover the window where visible changes happen — at a lower cost per bottle.

What if it doesn't work for me?

Every order is covered by our 90-day money-back guarantee. Use it consistently; if you're not happy with your results, contact us for a full refund. No questions asked.

When will my order ship?
