The Clinical-Grade Choice for Visibly Renewed Skin
Most "anti-aging" serums work on the surface. Nexia works at the source — using a bioavailable copper peptide complex to support your skin's natural renewal where it actually matters.
The result? A complexion that looks firmer, smoother, and more luminous — without the irritation of harsh actives.

Frequently Asked Questions
Find quick answers to the most common questions about our product.
Concentration and stability. Most budget copper peptide serums contain trace amounts — under the threshold studied in research. Nexia is formulated at 0.05% (clinical strength) and stabilized for full bioavailability. The label isn't the formula.
Completely. Retinol works by accelerating exfoliation, which is why it causes redness and peeling. GHK-Cu works by signaling — it supports your skin's natural processes without disrupting the surface. Most women with sensitive or reactive skin tolerate Nexia without irritation.
Hydration and glow within 1–2 weeks. Visible firming at 4–6 weeks. Bigger transformations continue through week 12 as your skin's renewal compounds. Stay consistent — copper peptides build results gradually.
Alternate, don't layer. Use Nexia in the morning. Use retinol or vitamin C at night. Mixing them in the same routine can reduce the effectiveness of both.
Return it within 30 days for a full refund. Empty bottle, half-used bottle — doesn't matter. The risk is on us, not on you.
