Frequently Asked Questions

How long until I see results?

Most customers report visible improvements within 2-4 weeks of consistent use. The GHK-Cu peptide, EGF, and Methylene Blue work synergistically to accelerate skin renewal and collagen production, with optimal results typically seen after 8-12 weeks.

How should I incorporate this into my skincare routine?

Apply to clean, slightly damp skin after cleansing and toning, but before heavier creams or oils. Use morning and evening for best results. Allow 1-2 minutes for complete absorption before applying other products.

Is this suitable for sensitive skin?

Yes, our formula is designed to be gentle yet effective. The ingredients are carefully balanced and have shown excellent tolerability in clinical studies. However, as with any skincare product, we recommend doing a patch test first.
