Question 1

What are copper peptides?

Accepted Answer

Small chains of amino acids bound to a copper ion — the most studied is GHK-Cu, a naturally occurring peptide the body already produces.

Question 2

How do copper peptides work?

Accepted Answer

They bind receptors on skin cells and upregulate collagen, elastin and antioxidant enzyme production, while delivering copper as a cofactor for repair enzymes.

Question 3

Are copper peptides safe long-term?

Accepted Answer

GHK-Cu is a biomolecule the body naturally produces. Decades of research support both efficacy and safety with topical use.

Question 4

What is the difference between GHK-Cu 1% and 2%?

Accepted Answer

1% is calibrated for daily use across every skin type. 2% is designed for advanced repair and mature skin — best introduced gradually and used at night.

Question 5

How long does a 30ml bottle last?

Accepted Answer

With twice-daily use (three to four drops per application), a 30ml bottle typically lasts 8–10 weeks.

Question 6

Are your products vegan and cruelty-free?

Accepted Answer

Yes — every ULTIMATE formula is vegan, cruelty-free, fragrance-free and formulated to pharma-grade standards.

Question 7

Can copper peptides be used with retinol?

Accepted Answer

Yes. Apply peptides first, wait two minutes, then apply retinol. Peptides help buffer retinoid irritation.

Question 8

Can I use vitamin C and copper peptides together?

Accepted Answer

Yes — apply vitamin C first (lower pH), wait two minutes, then apply peptides. Or split: vitamin C in the morning, peptides at night.

Question 9

What is Ectoin and why is it in the formula?

Accepted Answer

Ectoin is an extremolyte that forms a hydration shell around cells and protects against UV, pollution and dehydration. It pairs perfectly with copper peptides.

Question 10

Are your formulas suitable for sensitive skin?

Accepted Answer

Yes. Every formula is fragrance-free, non-comedogenic and gentle enough for reactive skin. Patch test any new active before full use.

Question 11

Can I use these products during pregnancy?

Accepted Answer

Copper peptides are considered pregnancy-safe in the peer-reviewed literature. We recommend confirming with your healthcare provider before starting any new skincare.

Question 12

What if my skin gets more sensitive after starting peptides?

Accepted Answer

This is usually caused by another active — pause exfoliants and retinoids for a week and reintroduce slowly.

Question 13

How long until REGEN6 shows results?

Accepted Answer

Reduced shedding is typically observed within 6–8 weeks. Visible regrowth and increased density typically appear between months 3 and 6.

Question 14

Can REGEN6 be used with minoxidil?

Accepted Answer

Yes — apply REGEN6 first, allow to dry, then apply minoxidil. Many customers use both in tandem.

Question 15

Is REGEN6 safe for women?

Accepted Answer

Yes. The formulation is designed for both male and female pattern hair thinning.
