Questions and answers.

Most bioactives are one compound purified in isolation. MCC is the complete conditioned medium a living cell secretes: 5,105 proteins and 15,540 peptides identified by DIA LC-MS/MS, alongside growth factors, a native exosome fraction, and salmon polynucleotides. Isolating one fraction (e.g. PDRN) discards the rest of the secretome; MCC's premise is that the whole medium is more representative of how these molecules occur biologically.

Yes, as a bioactive input, MCC has been studied clinically at a 50% w/w inclusion level. As a water-phase input, it is stable at higher concentrations. Cold process production is preferred.

The INCI name is Salmon Mesenchymal Cell Conditioned Media. MCC has informally been described as a salmon cell secretome; "Wild Salmon Stem Cell Conditioned Media," "Pacific salmon peptides," "PDRN+," and others are marketing descriptors, not INCI names.

Since isolating the starter cells from a single juvenile salmon in 2018, there has been no need to return to the animal. Today, MCC production is therefore animal-free, although not technically vegan because it traces to the original fish sample. Because production inputs are animal-free, MCC has drawn broad support from PETA and several other animal welfare organizations.

MCC is salmon-derived and contains salmon origin proteins. If you have a known fish or shellfish allergy, consult a professional before use, and patch-test first. Finished products containing MCC may require fish-allergen labeling depending on jurisdiction. Residual protein allergen testing data is available on request.

All MCC is produced in a repurposed brewery in San Francisco's Dogpatch neighborhood. The facility is FDA-inspected and cGMP-compliant. MCC is batch-tested with fully traceable production.

The salmon tint comes partly from cyanocobalamin (a form of vitamin B12) used in the cell nutrient media, and partly from carotenoid derivatives — the same class of molecules responsible for salmon's natural color.

No. MCC has a neutral odor profile.

No, the source cells are not edited or bioengineered. In addition, MCC only contains the molecules created by these cells; it does not contain the cells or any other living biological material.

The same cell culture process underlies Wildtype's cultivated salmon, which has undergone extensive review by the FDA for food production, generally a higher bar for safety than topical use. As with any cosmetic ingredient, allergenicity is possible; patch testing is recommended for sensitive skin.

Yes, several formulations and formats are ready for partner development. We supply the raw material, its full dossier, and claim-safe language; MOQ, lead time, co-branding, and territory terms are shared once we understand your format and volume. Start with a partner inquiry.
