Freshness Over Shelf Life
Most skincare is engineered to survive warehouses, heat, and long shelf lives. Ours is engineered to remain biologically active. To protect peptide structure and signaling ability, our serums are formulated without preservatives and delivered cold from formulation through shipment.
This is why we make everything in small batches.
This is why we prioritize bioactivity over long shelf storage.
This is why they work differently.

Refrigeration is recommended, not required.
Cu Glow serums are delivered cold to preserve maximum peptide bioactivity and freshness. When kept refrigerated, the peptides remain at peak signaling strength for the longest period of time.
If stored at room temperature, the serum remains safe and effective for everyday use. Over extended periods, warm storage may gradually reduce peptide activity, but it will not cause spoilage or make the product unsafe.
For best results, we recommend refrigeration. For convenience, room-temperature use is perfectly acceptable.
1. Apply to clean, slightly damp skin.
Peptides absorb best this way.
2. Use a pea-sized amount (about 4 to 6 drops).
Enough for the face, neck, or any area you want to renew.
3. Gently apply to skin, don’t rub.
Let it absorb for at least 60 seconds.
4. Follow with moisturizer (if needed) and SPF in the morning.
5. Start once daily.
Increase to twice daily only if skin feels comfortable.
6. Store cold to preserve bioactivity.
During the first 2–4 weeks, your skin begins its renewal cycle. GHK-Cu increases cellular turnover, stimulates collagen-producing fibroblasts, and helps remove older, damaged cells. As this transition happens, some users may notice subtle tightness or temporary dryness—this is simply your skin adjusting as fresher, younger skin comes to the surface. Over the next few weeks, the moisture barrier strengthens, the texture becomes smoother, and the overall tone appears more even and revived. If needed, apply a moisturizer after the serum or use it every other day as your skin acclimates.
Absolutely.
These areas respond extremely well to peptides and often show improvement even faster than the face.
Most users notice smoother, more hydrated skin in 1–2 weeks, with visible firmness and tone improvements in 4–6 weeks.
Because the skin mirrors what’s happening inside the body, results are even better when supported with healthy nutrition, hydration, and rest.
