Frequently Asked Questions

Everything you need to know about CuBio Labs Serum.

Copper peptides (GHK-Cu) are naturally occurring complexes that signal your skin cells to produce more collagen and elastin. They also have powerful antioxidant and anti-inflammatory properties. Our serum delivers a clinically-effective 2% concentration directly to the dermis.

Most users notice improved skin texture and radiance within 2–3 weeks. Significant wrinkle reduction and firmness improvements typically become visible after 6–8 weeks of consistent daily use. For best results, apply morning and evening to clean skin.

Yes. CuBio Labs Serum is fragrance-free, paraben-free, and dermatologist-tested. Copper peptides are actually known for their skin-calming properties. That said, we always recommend a patch test before full use, especially for those with reactive skin conditions.

We recommend separating copper peptides from vitamin C (ascorbic acid) as they can counteract each other. Copper peptides pair well with hyaluronic acid, niacinamide, and gentle moisturisers. If using retinol, apply CuBio Labs Serum in the morning and retinol at night.

We offer a full 30-day money-back guarantee. If you're not completely satisfied with your results, contact us within 30 days of delivery for a no-questions-asked refund — even on opened bottles. Your skin, your terms.
