GHK-Cu + Eyeseryl® + Argireline® + SYN-COLL®
(Custom Proprietary Peptide Complex)
Targeted Repair. Brighter Under-Eyes. Smoother, Firmer Skin.
Dark circles — puffiness — fine lines — tired-looking eyes
The CU GLOW Eye Renewal Serum is a concentrated under-eye treatment engineered to repair the thinnest, most delicate skin on the face. Using a custom proprietary blend of GHK-Cu, multi-action peptides, and our HA7 hydration base, this serum delivers visible tightening, brightening, and smoothing without irritation.
Where most eye creams rely on heavy oils or caffeine, this formula works deeper — sending targeted repair signals that help reduce puffiness, fade discoloration, and strengthen the under-eye structure over time.
It absorbs instantly with a cool-gel texture, making it ideal for both morning and night use
• Visibly refreshes tired, dull under-eyes
• Helps reduce the appearance of puffiness and under-eye bags
• Smooths the look of fine lines and crepey texture
• Supports firmer-looking eyelids and under-eye skin
• Brightens the appearance of dark circles over time
• Lightweight, fast-absorbing gel texture — no grease or residue
• Gentle enough for daily use on delicate eye skin
• Cold-kept and small-batched for freshness and potency
• Anyone with tired-looking or puffy under-eyes
• Those noticing fine lines, crepey texture, or loss of firmness around the eyes
• People with dark circles caused by stress, lack of sleep, or lifestyle factors
• Sensitive skin types who cannot tolerate heavy creams or caffeine-based formulas
• Anyone seeking a lightweight, non-greasy eye treatment that absorbs quickly
• Those looking for long-term improvement, not temporary masking
• Men and women who prefer clean, minimalist formulations without fillers or fragrance
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.
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 0.3%, 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.
Targeted support peptides for the delicate eye area
• Eyeseryl® – Helps reduce the appearance of puffiness and under-eye bags by supporting fluid balance and smoother-looking skin
• Argireline® – Softens the look of expression lines and fine wrinkles without irritation or stiffness
• SYN-COLL® – Supports collagen appearance to improve firmness, smoothness, and
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.
AM or PM — after serums, before sunscreen (AM only).
- Apply 2–3 drops to clean, slightly damp skin.
- Press gently over the face, neck, and chest.
- Use as the final step in your routine to lock in hydration and peptide serums.
- For extra nourishment, mix 1 drop with your CU GLOW peptide serum at night.
- Safe to use daily, even on sensitive or acne-prone skin.
Pro Tip:
Use on damp skin or 1 to 2 minutes after your GHK-Cu serum — this increases absorption and gives a silky, satin finish.
