How do I use the Accelerated Performance System?

The Accelerated Performance System (APS) is a two-step exfoliating treatment & hydrating serum and is a great treatment to minimize the appearance of acne scaring, dark spots and wrinkles. The 2 products within the system are used in the following systematic manner: 

In the evening, after using steps #1 & #2 of the Metrin Skincare System, apply #1 Revitalizing Glycolic Complex of the APS, and go to bed with it on (like an overnight mask) – no need to use steps #3, #4, #5 of the Metrin Skincare System after this.
The next morning, wash it off with #1 & #2 of the Metrin Skincare System, then apply #2 Reactivating Serum of the APS; once absorbed apply the #3, #4, #5 of the Metrin Skincare System as per usual!
*Use 1-3 times per week as needed.
