Crestella — The repair signal your skin stopped receiving

Most women notice a change in how their skin feels within the first week — softer, more hydrated, less tight. Visible structural changes — firmness, jawline definition, reduced crepey texture — typically begin at weeks three to four. By week eight you will have a clear answer. The collagen rebuilding process compounds over time which is why consistency matters more than quantity.

Most peptide serums use Argireline or Matrixyl — ingredients that work by relaxing facial muscles or stimulating collagen through general pathways. GHK-Cu is different. It is the specific copper peptide your body produced naturally every day of your adult life — the molecule that told your fibroblast cells to rebuild collagen overnight. After menopause your body stopped producing it. Crestella replaces it directly. You were not using the wrong product. You were using products that knocked on a door that was no longer answering.

Yes. GHK-Cu is one of the most well-tolerated skincare ingredients studied. Unlike retinol which works through pathways that post-menopausal skin often cannot tolerate — causing burning, peeling and irritation — copper peptides do not cause photosensitivity, peeling or inflammation. Your skin produced this molecule naturally for decades. You are not introducing something foreign. You are restoring something that was already there.

Yes — but we recommend applying Crestella first on clean skin and allowing it to absorb fully before applying retinol or acids. Some research suggests high concentrations of vitamin C applied simultaneously may interfere with copper peptide activity so we recommend using those at different times of day. Morning for Crestella, evening for actives, works well for most women.

HRT is a valid option and works well for many women. What copper peptides offer is different. HRT was designed for hormonal health — skin improvement is a secondary benefit that happens when rising estrogen levels eventually reactivate GHK-Cu production. Crestella delivers GHK-Cu directly to the skin cells that need it, without affecting your hormones at all. No prescription, no systemic effects, no ongoing monitoring required. Many women use both together successfully.

No. GHK-Cu works by reactivating dormant fibroblast cells — cells that are quiet, not dead. The repair mechanism does not have an expiry date. Several of the clinical studies on GHK-Cu included women over 65 and showed significant results. The older the skin the longer results may take to appear — but they appear. The door was closed. It was not removed.

One 30ml bottle lasts approximately 60 days with daily use. Apply 3 drops to clean skin on your forehead and cheeks every morning and night. Press gently with your fingertips — do not rub. Allow to absorb fully before applying moisturiser or other products. That is the complete routine.
