Neurogan Copper Peptides Face Serum — 1oz GHK-Cu 4% Niacinamide, Lightweight Hydrating Formula

This concentrated serum pairs 1,200 mg of Copper Tripeptide-1 (GHK-Cu) per ounce with 4% niacinamide and a hydrating base of aloe, glycerin, jojoba and rice bran oil. Formulated in Neurogan's GMP-certified San Diego facility, the formula is vegan-friendly, free from parabens and designed to layer cleanly beneath moisturizer, SPF and makeup. Expect roughly 60 applications per bottle; slight color variations and a natural lemon peel scent are normal.

How does the 4% copper peptide complex fit into a daily routine?

Use after cleansing and before thicker skincare steps to let the serum absorb fully. Apply three to five drops to face, neck and chest morning and evening, pressing gently until absorbed. During daytime use, follow with a broad-spectrum sunscreen.

• Apply on damp or dry skin after cleansing and toning
• Three to five drops per application — about 60 uses per 1oz bottle
• Layer under moisturizers, SPF and makeup without pilling
• Patch test before first full use

What’s in the formula and why those ingredients matter?

The serum centers on a high-concentration copper tripeptide (GHK-Cu) combined with 4% niacinamide for skin comfort and visible texture support. A hydrating base of aloe, glycerin, jojoba and rice bran oil keeps the sensation lightweight while helping skin surface feel softer. No parabens or unnecessary fillers are included; the light citrus aroma comes from lemon peel oil.

• 4% GHK-Cu Copper Tripeptide-1: 1,200 mg per ounce
• Niacinamide: supports an even-feeling skin surface
• Hydrators: aloe, glycerin, jojoba, rice bran oil for a non-tight finish
• Natural lemon peel oil scent; third-party lab tested for purity

Will this serum work with other active treatments?

The lightweight formula is designed to layer under most routine steps, but compatibility varies by individual. It absorbs quickly without greasiness, reducing the chance of pilling under moisturizers or makeup. If you use strong actives (retinoids, acids), introduce the serum slowly and patch test to check tolerance.

• Compatible under sunscreen and makeup due to fast absorption
• Introduce gradually with other potent actives to monitor tolerance
• Vegan and free from parabens and added fillers
• Recommended for both morning and evening routines

How should I store and use the bottle to get the most from it?

Keep the bottle capped and stored away from direct heat or prolonged sunlight to preserve ingredient stability. Because each 1oz bottle contains a concentrated 4% copper peptide complex, a small amount per use goes a long way. Follow label directions and use within the manufacturer’s suggested timeframe after opening.

• Store in a cool, dry place away from direct sunlight
• Cap tightly between uses to protect potency
• Approximately 60 applications from one 1oz bottle with 3–5 drops each
• Color may vary slightly between batches; scent comes from lemon peel oil
