The full-size Metrin Skincare System (165 ml/ 5.5 fl.oz) typically lasts 4-6 months, which is the same amount of time your skin requires to fully turnover and when you will see your best results.

The smaller sized systems, single bottles, and the Accelerated Performance System will run out before 6 months so they are instead covered under the 30-day guarantee.
