• Apply Acne Repair serum every morning followed by Litaderm serum. (If your skin tolerates Litaderm morning and evening).
• Use DermRepair morning and/or evening as needed (if and when you feel your skin needs extra moisture or anti-inflammatory treatment). 
• Either apply Litaderm serum every night and follow up (after 5 min.) with DermRepair, or alternate DermRepair and Litaderm serum at night.
• Very sensitive skin may only tolerate Litaderm serum once per day - either morning or evening. Some skin types may even be too sensitive for daily application, and will therefore need to apply Litaderm serum every other day until skin becomes more tolerant.
• Apply Chemical peel spray 2-3 times per week (depending on tolerability). Do not immediately follow up with DermRepair. DermRepair will alter the pH of Chemical peel spray, rendering it less effective.
