Can I use REDEFINE Intensive Renewing Serum with REVERSE Lightening Regimen?

After using REVERSE Lightening Regimen for 30 days, you can patch test REDEFINE Intensive Renewing Serum after REVERSE Skin Lightening Toner (Step 2) in Regimen and begin using it three times a week at night, increasing to nightly use as tolerated. And, of course, a broad spectrum sunscreen is the most important weapon in your anti-aging arsenal. REVERSE Broad Spectrum SPF 50+ Sunscreen is formulated to visibly decelerate the signs of early skin aging that appear over time.
