Skin Rejuvenation Peptide Protocol

GHK-Cu is a copper-binding tripeptide that modulates over 4,000 genes involved in tissue remodeling, activating collagen synthesis, glycosaminoglycan production, and metalloproteinase regulation. SNAP-8 (acetyl octapeptide-3) is a SNAP-25 mimetic that modulates neuromuscular junction signaling to reduce repetitive muscle contraction — it is the peptide analog of the mechanism behind botulinum toxin. Glutathione is a tripeptide antioxidant that protects against oxidative damage and inhibits melanogenesis via tyrosinase inhibition.

Route selection depends on the peptide. GHK-Cu: topical application (cream, serum) for localized skin effects, or subcutaneous injection (1-2 mg/day) for systemic tissue remodeling — both routes are supported in the literature. SNAP-8: topical only — applied as a serum to target expression areas. Glutathione: subcutaneous injection (200-600 mg), IV push, or oral/sublingual supplementation depending on research target.

Photograph target skin areas under standardized conditions: consistent lighting (natural daylight or ring light at fixed distance), same angle, same time of day. Use a color reference card in frame if possible. Document skin concerns, current skincare regimen, and any relevant medical history. If available, use skin analysis tools to measure hydration, elasticity, or pigmentation.

For topical GHK-Cu and SNAP-8: cleanse the target area with a gentle, pH-balanced cleanser. Pat dry. Apply peptide solution to clean skin — peptides should be applied before heavier creams or oils that may form a barrier. Allow 2-3 minutes for absorption before applying subsequent products. SNAP-8 is applied to expression line areas (forehead, periorbital, perioral). GHK-Cu can be applied broadly.

For injectable GHK-Cu: follow the Subcutaneous Injection Technique Protocol at 1-2 mg per day. For injectable glutathione: 200-600 mg subcutaneously, typically 2-3 times per week. Oral glutathione: 500-1000 mg daily (liposomal form preferred for bioavailability). Document doses, times, and injection sites.

Photograph target areas every 2 weeks using the exact same setup as baseline. Maintain a written log of subjective observations (texture, tone, fine lines, pigmentation, hydration). Minimum recommended research duration for visible collagen remodeling is 8-12 weeks, based on the collagen synthesis cycle timeline.

At the end of the research period, create a side-by-side comparison of baseline and final photographs. Compile all subjective observations and any objective measurements into a structured report. Note which peptides were used, exact concentrations, application frequency, and any confounding variables (sun exposure, dietary changes, other skincare product changes).
