Essential Peptide Serum — GHK-Cu 0.5% (15 mL)
GHK-Cu 0.5% • HA7 Base • Daily Collagen Renewal: Formulated without synthetic stabilizers or PEGs — visible peptide structures are a natural result of preserving bioactivity.
Gentle Strength. Daily Repair. Skin-Compatible Regeneration.
A minimalist, regenerative serum designed to support the skin’s natural repair process — without irritation, heaviness, or synthetic overload.
Powered by 0.5% GHK-Cu, a copper peptide naturally found in the human body, this formula sends biological repair signals that help restore healthier-looking skin over time.
What it does:
- Signals collagen and elastin support
- Helps calm visible inflammation
- Improves skin resilience and elasticity
- Supports smoother, more balanced texture
- Designed for daily, long-term use
Where most skincare sits on the surface, this serum works with the skin, not against it.
Formulated for beginners, sensitive skin, and anyone seeking real repair without compromise.
- Gentle, foundational daily repair with 0.5% GHK-Cu
- Softens the look of fine lines and early signs of aging
- Improves overall texture and radiance over time
- Strengthens the skin barrier and supports natural collagen production
- Helps calm visible redness and irritation
- Lightweight, hydrating texture that layers easily under other products
- Ideal “entry strength” copper peptide for first-time users
- Cold-kept, small-batch production to protect peptide structure and potency
- First-time copper peptide users or anyone with sensitive/reactive skin
- Those who want preventative, long-term repair rather than aggressive actives
- People who are already using retinoids or acids and want a balancing repair step
- Anyone looking for a simple, science-backed daily serum they can use year-round
- Ideal as the everyday base serum in the CU GLOW line routine (AM or PM)
This serum is built on a seven-molecular-weight hyaluronic acid complex, designed to hydrate skin at multiple levels simultaneously.
Each molecular size serves a different purpose:
• Larger weights hydrate the surface, instantly improving softness and smoothness
• Mid-range weights support elasticity and visible plumpness
• Smaller weights penetrate deeper to help maintain long-term hydration and skin resilience
Together, these seven weights create a hydration matrix that mimics healthy skin’s natural moisture system—delivering immediate comfort while supporting deeper repair over time.
This multi-layer approach allows the peptide to perform more effectively, rather than sitting on dehydrated skin.
GHK-Cu is a naturally occurring copper peptide found in human plasma, saliva, and urine. It plays a critical role in skin repair signaling.
At 0.5%, this concentration is optimized for daily use—strong enough to support collagen production and skin renewal, yet gentle enough for sensitive or reactive skin.
GHK-Cu helps:
• Signal collagen and elastin production
• Support skin firmness and elasticity
• Calm visible inflammation
• Improve overall skin tone and resilience
Rather than forcing change, GHK-Cu works by communicating with the skin, encouraging it to repair itself the way healthy skin naturally would.
This serum is intentionally not shelf-stable by design.
GHK-Cu is a biologically active signaling peptide. Like all
bioactive compounds, it is sensitive to heat, light, and prolonged room-temperature storage. Exposure to these conditions can gradually reduce
peptide integrity and effectiveness over time.
To protect potency, this formula is:
• Cold-stored
• Light-protected
• Produced in small batches
Cold preservation helps maintain the peptide’s structural
integrity, ensuring it remains biologically active when applied to skin.
This is not cosmetic skincare meant to sit unchanged for
years.
It’s functional skin repair, preserved the same way biologically active
compounds should be.
What That Means for Your Skin
• Stronger peptide signaling
• More consistent daily performance
• Less degradation over time
• A formula that stays true to its original potency
Why Most Brands Don’t Do This
Cold preservation requires:
• Smaller production runs
• Faster inventory turnover
• More intentional handling
Most brands choose shelf stability for convenience.
We chose performance.
- After cleansing, apply a pea-sized amount of serum to clean, slightly damp skin.
- Gently press into the face, neck, and any areas of concern (do not rub aggressively).
- Use once or twice daily – morning and/or night.
- Allow 60–90 seconds for full absorption before applying moisturizer or SPF.
- If your skin is sensitive, start with once daily for the first week, then increase as tolerated.
- Store in the refrigerator to preserve peptide strength and freshness.
