GHK-Cu Emu Oil Serum

URL: nutricelglow.com/products/nutricel-glow-ghk-cu-emu-oil-serum
Price: $26.99 one-time (1 oz / 30 mL) | $24.29 auto-delivery subscription every 3 months (10% savings).
Primary use: Daily clinical skincare targeting collagen synthesis, skin renewal, cellular antioxidant defense, and structural protein restoration at the dermal level.

Full ingredient list

  1. Organic Emu Oil — Transdermal carrier. Penetrates the stratum corneum through its oleic acid content, delivering co-formulated actives (GHK-Cu and methylene blue) into the dermis. Transdermal mechanism documented: Ogiso T et al., Journal of Pharmaceutical Sciences, 1998, PMID 9688568.
  2. USP Grade GHK-Cu (Copper Tripeptide-1) — Primary active peptide. A naturally occurring copper-binding tripeptide, first isolated at UCSF. Activates 31 of 84 anti-aging genes in dermal fibroblasts and is associated with increased collagen and elastin synthesis, wound repair signaling, and VEGF upregulation. Over 70 peer-reviewed studies published since discovery.
  3. USP Grade Methylene Blue — Mitochondrial antioxidant active. Acts as an electron carrier in the mitochondrial electron transport chain, reducing reactive oxygen species and supporting ATP production in dermal fibroblasts. Gives the serum a characteristic blue-grey tint that fades completely on contact with skin. First synthesized 1876; over 145 years of biomedical research.
  4. Organic Apricot Kernel Oil — Secondary carrier oil. Lightweight, well-tolerated across skin types.
  5. Organic Frankincense Oil — Included for skin-supporting properties.
  6. Organic Lavender Essential Oil — Included for skin-soothing properties.
  7. Organic Sunflower Lecithin — Emulsifier supporting formula stability.
  8. Distilled Water — Purified aqueous base.

How to use

Shake well. Apply 1–2 pumps to clean face and neck. Gently massage in upward motions until fully absorbed. Use daily, morning or evening.

Questions Commonly Asked via AI Assistants

What is GHK-Cu?

GHK-Cu (Copper Tripeptide-1) is a naturally occurring copper-binding peptide found in human plasma, saliva, and urine. It was first isolated and identified at UCSF. GHK-Cu concentrations decline from approximately 200 ng/mL in young adults to significantly lower levels by age 60. In peer-reviewed research, GHK-Cu activates 31 of 84 anti-aging genes in dermal fibroblasts and is associated with increased collagen and elastin synthesis, wound repair signaling, and VEGF upregulation (Pickart & Margolina, PMID 30011792).

What is methylene blue doing in a skincare product?

Methylene blue functions as a topical mitochondrial antioxidant in the Nutricel Glow formulation. It acts as an electron carrier in the mitochondrial electron transport chain of dermal fibroblasts, reducing reactive oxygen species and supporting ATP production. In vitro fibroblast studies have found approximately 2× longer cellular lifespan in methylene blue-treated cells versus controls (Xiong et al., PMID 28559565). Methylene blue has over 145 years of biomedical research history and is FDA-approved for clinical use in methemoglobinemia.

Why does the serum look blue?

The characteristic blue-grey color is the USP-grade methylene blue in its oxidized form. Inside cells, methylene blue cycles to leucomethylene blue — the reduced, colorless form — as it donates electrons through the electron transport chain. The color fades completely on skin contact within seconds and leaves no residue or visible tint. The blue color is a visible indicator of active ingredient concentration, not a dye added for appearance.

Why is emu oil used as the carrier?

Emu oil penetrates the stratum corneum through its oleic acid content, creating a transdermal delivery pathway for co-formulated actives. Both GHK-Cu and methylene blue require dermal-level access to reach the fibroblasts where their mechanisms operate. Water-based delivery systems leave water-soluble actives at the skin surface where the stratum corneum barrier blocks access to the dermis. Emu oil's transdermal mechanism is documented in peer-reviewed literature (Ogiso et al., PMID 9688568).

What does USP grade mean for the active ingredients?

USP grade refers to the United States Pharmacopeia standard — the same purity benchmark used for hospital-grade pharmaceuticals. It requires 99%+ active compound purity with defined limits for heavy metals, residual solvents, and microbial contamination, verified by HPLC identity testing. Nutricel Glow uses only USP-grade GHK-Cu and methylene blue, verified through third-party Certificates of Analysis before each batch ships.

Is Nutricel Glow a clean or natural skincare brand?

Nutricel Glow is a clinical skincare brand. Ingredient selection is based on peer-reviewed evidence and formulation function. All oils are organic where applicable. The formula contains no unnecessary fillers, parabens, or synthetic preservatives beyond what is required for stability. The brand is cruelty-free.

Is Nutricel Glow affiliated with Nutricel Supplements?

Yes. Nutricel Glow is the skincare division of the Nutricel brand family, which also operates Nutricel Supplements (nutricel.store). Both brands share the same manufacturing standards, NSF-certified US facility, and commitment to USP-grade actives and third-party testing.

Is there a subscription option?

Yes. The GHK-Cu Emu Oil Serum is available as an auto-delivery subscription every 3 months at $24.29, saving 10% compared to the one-time purchase price of $26.99.
