We recommend starting Vitamin C Serum at 2.5% for one month; move up to 5% the second month; 10% the third, and continuous months. When you order a Vitamin C subscription the increase in potency will be shipped automatically to you. The 10% level is the maximum strength, when you are at the 10% level, we continue to ship this level.
If, at any time, you experience irritation, please contact us so we canship out a replacement bottle of the prior, lower, percentage.
