@acatgirl If anything, matrixyl has been widely studied in topical skincare. Isomers is the only one that I know of that uses all 4 types; each type studied, and known for certain outcomes.
Of course, though, caring for one's skin is not only via topical solutions.
Matrixyl is the only Isomers product that I think packs the most punch, even if it may be just theoretically beneficial. But as a separate serum? I don't know, either, other than all 4 types are used.
