How long your products last depends on how you use them. But because there are no ingredients in our products that dilute their effectiveness, a little Farrow goes a long way. If using a pea-sized amount daily, your jar of Farrow Facefood should last about a month. But if you use Farrow Facefood or Skinfood more slowly, that’s okay too. There’s nothing in Farrow creams that causes them to spoil either, so they will be good for up to six months.
