About this formula
The complete firming routine: Impulse Peptide Firming Serum for the morning, Cortex Retinal 0.1% for the evening, Cortex Night Cream to buffer and seal it, and Orbital Eye Serum for the eye area.
Includes a printed retinoid ramp-up schedule, because the reason most retinoid routines fail is that people start nightly and quit in week three. Approximately three months of use.

“Took about six weeks before I could see it, which the page did warn me about. Glad I did not give up at four.”
