  While chirality makes a difference for drug actives, I've not seen any evidence that it matters at all for cosmetic actives.

  As @Perry said, chirality is important for biological systems and hence pharmaceuticals, but sometimes, just sometimes, chirality has also an effect on physics. Something deep in my brain tells me that there are a few cosmetics ingredients with a mild difference between stereoisomers... it wasn't simple acids.

  @Pharma
  As far as I know only panthenol (topical), dextro vs levo.
