Can I go through the diagnostic process once and receive the product regularly?Updated a year ago

We don't recommend it. The skincare product you receive is based on a diagnosis of your skin's needs at a specific time. Your skin's needs change, though (depending on the season, diet and lifestyle changes, etc.) and so we recommend re-assessing your skin for each additional order. The diagnostic process is quick and simple, and your resulting product will be so much more effective. (Yes, it is that accurate!)
