How is StemFactor MD different from StemFactor?

Both are built on stem cell and fibroblast conditioned media. StemFactor MD is the more concentrated professional-line formula and adds blumea balsamifera and flame tree flower extracts plus lactic acid.

Is it made with plant or human stem cells?

Osmosis lists human stem cell conditioned media and human fibroblast conditioned media. These are lab-grown liquids, not the cells themselves.

Can I use it with vitamin A?

Yes. Apply StemFactor MD first, then follow with your other serums and moisturizer.
