Frequently Asked Questions

Q: What does GHK-Cu copper peptide do for the skin?

A: GHK-Cu is a naturally occurring copper peptide complex known to support skin's structural proteins. It helps visibly firm the skin, improve overall texture, and contribute to a more youthful, healthy-looking complexion with consistent daily use.

Q: Can I use this Hoygi copper peptide serum with other skincare products?

A: Yes! The lightweight, fast-absorbing formula layers beautifully under moisturisers, SPF, and makeup. For best results, apply the serum to clean skin before heavier creams or oils, and allow it to fully absorb for 30–60 seconds first.

Q: Is this serum suitable for sensitive skin?

A: The Hoygi GHK-Cu Serum is formulated for all skin types and contains no high-concern chemicals. However, as with any new skincare product, we recommend performing a patch test on a small area of skin before full facial application.

Q: How long will a 30ml bottle last?

A: With daily use (morning and evening), a 30ml bottle typically lasts approximately 4–6 weeks. The 60ml and 120ml options offer even better value for long-term use.
