Overview
Methylene blue is a phenothiazine dye with an unusually long scientific history — it was the first fully synthetic compound used as a medicine, and it remains a workhorse redox indicator. Its interest in cell biology comes from its behaviour at low concentrations as an alternative electron carrier: it can accept electrons from NADH and deliver them further down the mitochondrial electron transport chain, bypassing complexes whose activity is impaired, which in cell models has been associated with reduced reactive oxygen species and extended fibroblast lifespan in culture.
This 30 g cream places methylene blue in an emollient base at a low, tint-free concentration — deliberately far below the roughly 0.05% level at which the dye leaves visible blue staining on skin. Keeping the concentration in the sub-staining range is what makes the material practical for skin models, since visible colour otherwise interferes with photographic and colorimetric endpoints.
Methylene blue is a small molecule rather than a peptide, so it sits in this catalogue as a companion compound to the copper-peptide and cosmetic-peptide formats rather than as a peptide product. It is supplied lot-numbered and shipped from the United States for laboratory research only.

Questions about Methylene Blue Face Cream
What is in this cream?
The active is methylene blue, a redox-active phenothiazine small molecule, formulated in an emollient cream base at a low tint-free concentration. The exact figure for your jar is printed on the lot label. The 30 g jar is the only size offered.
Will it stain skin or surfaces blue?
The formulation is kept below the concentration at which visible staining appears on skin, roughly 0.05%. Methylene blue nonetheless stains textiles, paper and porous surfaces on contact, so gloves, a protected work surface and prompt cleanup of spills are sensible precautions.
Why is methylene blue studied in skin models?
At low concentrations it acts as an alternative electron carrier in the mitochondrial electron transport chain. Cell-culture work has reported reduced reactive oxygen species and delayed senescence markers in human fibroblasts under those conditions. These are in vitro observations in specific models.
Is this a peptide product?
No. Methylene blue is a small synthetic molecule with CAS 61-73-4, not a peptide. It appears in this catalogue as a companion compound to the copper-peptide and cosmetic-peptide topical formats, and documentation for the active is available on request.
How should the jar be stored and sampled?
Keep it closed, cool and out of light, ideally refrigerated. Take aliquots with a clean spatula instead of dipping used tools, weigh quantities for quantitative work, and log the lot number with the opening date so measurements stay traceable to a specific fill.
What does research use only mean for a topical formulation?
This preparation is supplied as a laboratory research material for bench and model work such as ex vivo skin, reconstructed epidermis or stability testing. It is not a licensed cosmetic, drug or medical device, has not been reviewed by the FDA, and is not intended for human or veterinary application.
