Bakuchiol is the active ingredient from Babchi seeds that has the same effect as retinol (research based). The difference is that Babchi Oil (or extract) contains approximately 1-12% Bakuchiol and the Bakuchiol we use contains 99% Bakuchiol. Many other brands do indeed use Bakuchiol as well, but often the INCI (ingredient) list states Babchi Oil or Bakuchi or Psoralea Corylifolia. That is not the Bakuchiol that was used for the scientific research and it has, quite relevant as well, higher photosensitivity because of the large amounts of psoralens (compounds of the Babchi plant), so it can actually make skin more sensitive.
