About

A skin-softening ingredient made by fermenting milk. Mild exfoliation from lactic acid and hydration from peptides. Generally safe but a theoretical issue for severe dairy allergies.

Skin benefits

  • Contains lactic acid and peptides that mildly exfoliate and hydrate
  • Skin-conditioning effect from fermented milk proteins
  • Long tradition of cosmetic use

Known concerns

  • Dairy-allergen potential for sensitive users
  • Compositional variability by strain and substrate
  • Preservation needed; ferments can carry microbial risk if poorly stabilised
