I would recommend starting out by using the AHA in the evening. I would apply your renova, wait a few minutes for it to absorb appropriately, then apply the AHA over it. In the a.m., apply your Vitamin C followed by a broad spectrum sunscreen of SPF 30 or greater.

The AHA can be used both in the AM and PM. However, you may want to start only in the morning. After washing your face in the evening you should use the Vitamin-C to a pH balancing toner. You also need to switch the Renova for Retin-A. The Renova is a combination of Retin-A and mineral oil. The mineral oil clogs your pores and prevents the Retin- A from penetrating to the cells where it can do what it is supposed to do. You also need to make sure the sun block protects from UVA. SPF tells you only how well it blocks UVB. There are only 2 ingredients that block UVA. They are avobenzone and Zinc Oxide. Of these, only the Zinc Oxide which goes on clear, is practical.
