Jane Iredale Bases don’t clog pores because they do not contain talc. Minerals will look after your skin.

Wash once a day with a foaming cleanser like Guinots Microbiotic Mousse and tone with Microbiotic Lotion. Exfoliate twice a week with Gommage Grain D’Eclat and moisturise am and pm with Crème Pur Equilibre or Matizone and finally use Gommasque twice a week.
